The Ten Most Interesting Animal Species You Probably Haven't Heard Of

Blake has been an online writer for over four years. He's passionate about video games, science, and entertainment.

Earth's Most Interesting Animals

Turns out the animal world isn't just about lions, giraffes, dogs, cows, and cats. Mother Earth contains many creatures that are just now being discovered by scientists, and not only at the bottom of the ocean. A six-foot-long tree lizard and a new African antelope were discovered in the last couple of years. If you're not a scientist, you may find you have some news to catch up on.

10. English Angora Rabbit

Strigops habroptilus (a domesticated variety)

The English Angora Rabbit is the product of hundreds of years of domestic breeding for its wool. The result looks something like a cat that has touched a power line, a cotton ball with a face, or a sheep that's been through a straightener. There are actually multiple breeds of this rabbit, and they were very popular among French royalty. I'm curious if Elmer Fudd would want to hunt one of these guys.

9. Dumbo Octopus


This little guy can be found really, really deep in the ocean. By deep, I mean 7000 meters deep. He's not called the Dumbo Octopus because of his intelligence, either. He uses his ears to swim. Why does this guy make the list? Because he's kind of cute, despite being used to swallowing his victims whole. No need to worry, he's only about 20 centimeters long, full grown. Scientists don't know all that much else about him.

If you lived that deep, you'd look like that too.

8. Blobfish

Psychrolutes marcidus

Golly-gee, that's one ugly creature. What was evolution thinking?

You might guess that the blobfish isn't a fast swimmer. It doesn't even have to swim most of the time, as its body tissue is slightly less dense than water, allowing it to float effortlessly just off the bottom of the ocean, waiting for its dinner of microorganisms to float by. How does it survive not being eaten? By not being tasty. In fact, it's inedible to humans. It's still endangered, though; overfishing of the ocean bottom leads to these guys being hauled out of the ocean at a fast rate.

To be fair, in its natural habitat, the blobfish might look somewhat less hideous than these shapeless, decompressed victims that have been hauled to the surface; see the artist's drawing below.

7. Kākāpō

Strigops habroptilus

The kākāpō is the world's largest parrot. It evolved into such a large and peaceful bird because of the former lack of mammalian predators in its island home in New Zealand. Among its qualities: it smells weird, barks like a dog, and is portly and nocturnal.

It is critically endangered (there are less than 300 left, and most of these individual kākāpōs have names). When Europeans brought dogs and cats over to New Zealand, these animals learned the kākāpō's smell, and were able to find them with ease. Once again, an example of humans messing with nature. Poor kākāpōs. At least it is fun to say their name.

Without arms it would be a snake or giant worm, both of which would cause me fear.

6. Olm

Proteus anguinus

Q: What has three toes on its front limbs, two toes on its back limbs, pale human-like skin, is blind, lives to age 100 (some say only 60), lives in caves, and can go ten years without food?

A: You should have guessed from all those hints (and the subtitle) ... the olm.

This blind salamander of the limestone caves of southern Europe is not much like any other amphibian. The olm has a great sense of hearing and of smell. Its olfactory system is so well-made that it can sense how many little living things surround it. Many a fisherman became a believer in sea monsters after catching one of these creatures ... just check out the picture above.

5: Matamata Turtle

Chelus fimbriata

This South American freshwater turtle makes the list because he looks like a tank. The matamata looks bulletproof, fireproof, radiation-proof, and, toughest of all, child-proof. I'm not sure about any of those claims, though, as I didn't run into any support during my research. Though the shell and head look extremely tough (and probably are), they are meant for camouflage; the matamata is said to resemble a chunk of bark with dead leaves. From above, he would be very hard to see sitting on the bottom of a creek, and also a nasty surprise if you stepped on him. I say this as a person afraid of snakes and spiders. I can't imagine how the person who discovered this river monster felt.

4. Barreleye Fish

Macropinna microstoma (and other fish in the family Opisthoproctidae)

The barreleye in the video above is one of the few ever seen alive with its distinctive transparent head. Although it has been documented since 1939, in early specimens, nets or lines had pierced and deflated the fluid bubble that makes this fish so unique.

The transparent head works like a cockpit in a fighter plane. The fish can rotate its eyes backward and upwards to see prey and predators. Useful, eh? It also is one of the few animals on earth that can put its anatomy on display without dying.

Too bad it dwells in such deep water, or else I'd buy an aquarium for one of those things with my HubPages earnings.

3. Tarsier

Family Tarsiidae

Tarsiers are interesting creatures. These little guys grow to be a whopping five inches. They eat insects and have been known to jump from tree to tree and eat birds.

Wait, what?

That's right. They're nocturnal and move very, very fast using their bony fingers and long tail. Females usually have about one little baby tarsier per year. What else is unnatural about these creatures? They can twist their heads 180 degrees like an owl. If they were any bigger, I'd be terrified of them.

This once again proves that Mother Nature has more creativity than science fiction writers.

2. Flying Squid

Several species, including Todarodes pacificus, Ommastrephes bartramii

Flying ... Squid?

I couldn't find much information on flying squid because people have been mistaking them for flying fish. Only within the last 20 years was the flying squid seriously talked about in academic circles. If you readers have been on the water much, you know that flying fish just zoom by, and it is hard to distinguish their finer features from a boat. Flying squid are even rarer and zoom by just as fast.

Scientists recently confirmed that there is a flying squid known as the "red" or "neon" flying squid. But it's blue. We don't know how they jump out of the water, why, or apparently even what color they are. More research needs to be done on these things.

It was tough even finding a good picture.

Number 1 (and My Favorite): Darwin Bark Spider

Caerostris darwini

Darwin's Bark Spiders were a recent discovery (2009) for the world at large; here are some pictures and discussions (in National Geographic) from the scientists who first documented them.

Of all these creatures, they mystify me the most. A couple of facts: First, their silk is much stronger than any other spider's silk that has been studied. It is 10 times stronger than Kevlar (that stuff in bulletproof vests). Second, and probably related, they somehow string their webs across, not along, rivers...don't you have to have two people to string something across a river? Maybe they swim across; who knows? Their webs are the biggest and strongest spiderwebs ever discovered.

The best way to study them is by boat because that's the only way scientists can analyze their behavior from up close. Much about them is still unknown because, for a long time, only local Madagascar rangers and tour guides knew about them.

They eat bees, dragonflies, and mayflies (up to 32 mayflies have been found in one web at a time). People wonder if their webs can catch birds, too.

Webs can reach 25 m across a river (perhaps more)

Bonus: The Mimic Octopus! How Could I Forget...

Thaumoctopus mimicus

The Mimic Octopus was discovered in 1998, in shallow, murky Indonesian seas. What makes it special? Watch the video below and see for yourself. It can mimic many underwater species, and mimics them very well indeed. In one example, it mimics a crab so that real crabs think that the octopus is a mate. Only then does it devour the (probably shocked) crab that is trying to mate with it. Nature is a cruel, cruel beast. Imagine laying down with a hot date you picked up at the bar, only for it to turn into a ravening grizzly bear waiting to devour you. Ugh.

In another instance, the mimic octopus tricks one of its predators into thinking it's a snake by burying six to seven legs in the ocean floor. The snake that it's mimicking, by the way, preys on the fish that preys on the octopus. Extending the metaphor from before, one could say that is basically the same thing as your McDonald's chicken strips turning into something that looks like a ravening grizzly bear waiting to devour you. Smart, eh?

Intelligence: One Last Thought

I'd like to bring up another point. At times I've discussed the idea (pardon my lack of sources and extended use of parentheses) that one measure of a species' intelligence might be how well it survives over very long periods of time.

Of course, many people assume that humans are the most intelligent species. A very strong case can be made for that. However, as a purely hypothetical thought experiment, let us imagine that humans make weapons that, hmm, well, might be able to destroy entire cities. Let us further posit that humans might use this superweapon on each other in the course of human disputes over political ideas. In this hypothetical case, the world could be turned to ruin, and humans essentially wiped from the face of the planet, along with many other poor animals who got in the way. This scenario is not entirely inconceivable; let's face it, we've ruined many, many natural habitats doing our thing and karma is not really on our side.

Consider also that humans as we know them have been on the face of the earth for MAYBE two to three million years. Our newly discovered friend, the mimic octopus, however, has most likely been happily doing his thing for millions and millions of more years, safely and discreetly at the bottom of the ocean.

So—humans are smart enough to create a weapon of incredible power, and some other cool stuff like the drive-thru, but dumb enough to blow ourselves up because we don't know if we like communism or democracy better. The octopus is smart enough to mimic at least five or six different animals and also likely smart enough to live to see its great-great-great-great-(x50)-great-grandchildren. Which is smarter?

Interesting animals. I had two angora rabbits a long time ago. Thought I would breed them and spin the wool. Not as easy as it sounds.

Kedgehog on February 25, 2019:

Octopi is wrong, as it Octopii, it is either octopuses or octopodes

Bree the Artist on January 23, 2019:

This is awesome! I would have never imagined there was such a thing as a poofball rabbit or flying squid.. We need to keep these creatures safe and protect them at all costs! Even you, blobfish.

Can I just say, about 90% of all the animals on these types of website are endangered it is just SO DISGRACEFUL what we humans are doing to Mother Nature and the planet at this rate animals like tigers etc. that have been around for years are all going to be wiped out why can't some people just DO SOMETHING?! #savetheplanet

Allie on March 17, 2018:

All animals, birds, fish etc.....seem to have a much higher intelligence than humans........either way......both can be kind, useful and interesting, yet some don't seem to carry those qualities.....

bib on October 30, 2017:

You neglected to mention that octopodes/octopi/octopuses (all of which are correct) are believed to have been the first actually intelligent (as in probably conscious) lifeform. Early octopi evolve as much as 400 million years ago, and exhibit astonishing intelligence. So maybe they, are actually the REAL brainchild of the creator, or masters of the universe. You never know.

Cute creatures and always interesting to see new life :). Thank you for sharing

ratnaveera from Cumbum on April 29, 2014:

Very interesting to learn about these animal species. Dolphins are also have importance since they behave as friends to human. Many interesting species of birds and animals can also be found in Amazon rainforest. Thanks for this great Hub with valuable information! Thumbs Up! Awesome!

Blake Atkinson (author) from Kentucky on March 07, 2014:

Glad I could help!

Avnoor Sidhu on March 04, 2014:

i think the blobfish looks cool but squishy, ugly and on...........................!

i was doing an animal report on one of the animals but, i couldn't decide on what to do it on so i came to this website to find an animal that know one has ever heard of so i picked one of the animals from this website! THANK-YOU! for helping me find an animal to do a report on once again THANK-YOU!

Blake Atkinson (author) from Kentucky on December 10, 2013:

I agree stuff, the Mantis shrimp is awesome. I'm thinking about doing another article about interesting ways animals catch their prey (my first one of that variety is on Squidoo), and the Mantis shrimp would probably be on that list.

stuff on April 26, 2013:

I think the Mantis shrimp should be added

FullOfLoveSites from United States on March 14, 2013:

Yes, they are indeed interesting and some are really cute, like the dumbo octopus. I am eager to watch a vid of that swimming with its ears flapping. The matamata turtle looks like a Pokémon creature. Voted up and awesome, funny and interesting.

taqito jr. on March 06, 2013:

i think this is very interesting because when you dont know about an animal it makes it worth wild

vibesites from United States on September 11, 2012:

The blobfish is like an old guy with a really big big nose. So funny! :)

hiruni on September 09, 2012:

thanks a lot

Swinter12 from Earth on September 06, 2012:

This was a fun article to read!

The Dumbo Octopus looks like a toy for some reason, like the avatar of the pacman game. The dumbo octupus was one of my favorites along with the Tarsiers; they're just both so adorable.

Nonetheless, it is impressive what that spider and the mimic octopus are capable of.

Voted Up and Awesome.

lyka gimena on August 03, 2012:

i like the different animals.these animals are very beautiful and wonderful.tnx for sharing.

Wow ! Never seen a Tarsier before , great hub !

Gypsy Willow from Lake Tahoe Nevada USA , Wales UK and Taupo New Zealand on July 15, 2011:

Another great hub thank you. I actually kept angora rabbits as I am a spinner and I have a soft shawl i made from their wonderful fleece combings. Love your style. Howabout doing a series on weird stuff and publishing a book, maybe an ebook? Keep em coming!

Greensleeves Hubs from Essex, UK on June 25, 2011:

Thanks for the link - even slugs can be beautiful!

Blake Atkinson (author) from Kentucky on June 25, 2011:

Thanks Greensleeves! Speaking of which, this came out today about new species discovered in the Philippines in 2011:

Thought you might like it, I sure did.

Greensleeves Hubs from Essex, UK on June 24, 2011:

Interesting stuff about interesting creatures; especially the ocean dwellers - we're discovering more and more oddball creatures in the ocean's depths, and they seem to be getting odder with each voyage of discovery. Thanks for sharing.

Blake Atkinson (author) from Kentucky on June 14, 2011:

Thanks Ilana! Yeah most of them weren't cute, but the Tarsiers were haha. I look forward to reading more of your hubs :)

Ilana Moore on June 14, 2011:


these are so cool! I really like the Tarsiers. Super cute, I'd like to keep one :)


Blake Atkinson (author) from Kentucky on June 10, 2011:

@xcentric stylo. Thank you! I'm glad you enjoyed it

@Jill of all trades... First of all I like your username. But I'll definitely check out your article because Im very interested in these types of things. That's awesome about the tarsier. I figured there were a few people out there that this hub wouldn't surprise too much haha

jill of alltrades from Philippines on June 10, 2011:

I like the way you wrote about these animals. I know about them or I am familiar with most of them since I am a zoologist. The tarsier is actually endemic to an island here in the Philippines and I have held it just like that in your picture. Check out my hub on Bohol.

Voted up and useful!

Blake Atkinson (author) from Kentucky on June 09, 2011:

Thanks Nathaniel! Yeah I'm always afraid to piss people off though because it seems many people are touchy on the whole creationist/evolutionist split. It's good to see that you read my article so soon after I published it haha.
