In honor of World Elephant Day, we present you with 12 little known facts about one of our favorite creatures
in GIFs, of course.

1. Elephants know every member of their herd and are able to recognize up to 30 companions by sight or smell. 

image

2. They can remember and distinguish particular cues that signal danger and can recall locations long after their last visit.

image

3. An elephant’s memory is not limited to its herd, nor is it limited to its species. In one instance, two circus elephants that performed together rejoiced when crossing paths 23 years later. Elephants have also recognized humans that they once bonded with after decades apart. 4.

5. The elephant brain is remarkably similar to the human brain, with as many neurons and synapses, as well as a highly developed hippocampus and cerebral cortex.

image

6. Elephants are one of the few non-human animals to suffer from post-traumatic stress disorder.

image

7. Elephants are creative problem solvers. 

image

8. Don’t try to outsmart an elephant! They have an understanding of basic arithmetic and can even keep track of relative quantities.

image

9. Elephants communicate using everything from body signals to infrared rumbles that can be heard from kilometers away. Their understanding of syntax suggests that they have their own language and grammar. 

image

10. Elephants can recognize 12 distinct tones of music and recreate melodies.

image

11. Elephants are the only non-human animals to mourn their dead, performing burial rituals and returning to visit graves. 

image

12. Elephants are one of the few species who can recognize themselves in the mirror.

Given what we now know about elephants, and what they continue to teach us about animal intelligence, it is more important than ever to make sure that these magnificent creatures do not vanish.

Despite an increase in awareness and advocacy across the globe, elephants are still a highly vulnerable population. Consider adopting an elephant or donating to one of many organizations that work to conserve elephant populations! ❀

earthstory:

animal.radical The Abdopus octopus, or algae octopus, isn’t your typical octopus. When the tide goes out you just might see the Abdopus out of the water moving along dry land. Found along the Indonesian, Philippine, and Australian coastlines they use their suction cups to pull themselves along, moving from pool to pool to look for food.
_
The Abdopus feeds on small crustaceans using its sharp beaks to drill through the exoskeleton to reach the soft muscle inside. But they can’t stay out of the water too long because they still depend on it to keep their skin moist and to supply them with oxygen. 🐙

Crinoid head

These animals, relatives of starfish and sea urchins somewhat resembling sea anemones that nearly disappeared in the Cretaceous Tertiary mass extinction were once the dominant filter feeders of Mesozoic shallow seas. We discussed them in a post before, available at http://tinyurl.com/nnap5t9, but used a photo of the more common stem sections as illustration. Here is an image of one of their filter feeding heads, looking like something out of a horror flick.

This T-Shirt was created by the founder of MagnificoGreatWhites, with 10% of the proceeds being donated to a Shark&Manta Conservation Group, and the remaining funds being dispersed between Great White Shark conversation groups not listed under TeeSpring. Shark finning is the removal of shark fins, afterwards the shark is discarded back into the ocean to slowly die by starving, drowning, or from being eaten alive by other fish. All species of sharks are at risk, and the demand for Shark fin soup is still on the rise. Millions of sharks are killed each year for this, causing a drastic decline in the number of sharks in our ocean.

conservationists ocean ramsay and lesley rochat are filmed swimming with sharks in order to help dispel myths concerning the public’s perception of the animal, and to raise awareness regarding it’s diminishing numbers in the wild. 

says ramsey, “it’s difficult to express the incredible joy and breathtaking emotion experienced 
watching the shark acknowledge and observe me, while i peacefully and calmly allowed it to swim towards me, and then experiencing it accepting my touch, allowing me to dorsal and tail ride.”      

she adds, “given the number of surfers and swimmers who frequent shark territory in low visibility often dressed in black wetsuits or floating on surfboards portraying a seal like silhouette, it is a huge testament to sharks sensory systems and intelligence that mistaken identity bite ‘attacks’ are so rare.”   

in fact, as rochat notes, only five people on average are killed by sharks every year, which is less than number of people killed each year by faulty toasters or falling off chairs. in contrast,  approximately  70 million sharks killed each year by humans.

“it’s important for me to walk my talk and show people that sharks aren’t monster man eaters with insatiable appetites for humans, but rather beautiful animals we ought to respect and protect,” rochat says. “they really are baldly misunderstood and need all the help they can get.” (x, x, x)

Sharks: Not Vicious, Just Mouthy and Inquisitive

In lieu of all of the sensationalist shark media occurring out there this summer, let’s talk about shark behavior and, in specific, shark attacks and white shark.

Some basic white shark facts (and yes,

Carcharodon carcharias is often also officially called the great white, but that just exacerbates all the media attention, so white shark it is). Whites are huge pelagic (open water) sharks that get on average 4-5 meters long, and their only known predator as an adult are orcas. They’re one of the longest lived cartilaginous fish known with a lifespan that appears to extend into their 70â€Čs. They have hella tons of teeth and lots of rows of them, so that when one pops out the next just pops into place as if on a conveyor belt. A white shark’s bite force is something like 4000 pounds per square inch from a six-foot-long animal. (Thanks to wiki for all the basic facts). 

Have a white shark anatomical drawing from wiki, because while it’s nightmare-inducing, it’s the only thing about sharks that should be.

People love to talk about sharks as these horrible monsters of the deep, eating everything they come across with gruesome abandon. This is just ‘perfect’ for summer, when sharks start showing up on beaches in the US and scaring the bejeezus out of basically everyone. 

Luckily, those people are making things up. You’re more likely to die because you shook a vending machine and it fell on top of you than you are to get bitten (note: not attacked) by a white shark. There’s a couple things you’re got to know about how sharks function to understand why worrying about getting nommed on by one at the beach is pretty silly. 

To start, they’re not man-eaters. Sharks don’t even know what a human is. We’re not aquatic organisms and they’ve probably only rarely encountered humans before, so there’s no reason to assume they’re going to be like ‘omg tasty hooman’ and charge over for a snack We don’t fit into what sharks consider prey, so they’re not going to prey on us intentionally. 

However, they do prey on seals. Tasty, blubbery, freaking-stupidly-clever-and-fast seals. And a human on a surfboard (which is when almost all shark encounters happen that result in injury) happens to look mightily like a seal if all you can see is a silhouette. More importantly, it’s a slow, stationary seal, which implies an easy meal. Most of the time, sharks ‘attack’ surfers thinking they’re seals. And guess what? Humans do not have all that tasty, energy-loaded blubber that seals do. We’re pretty bony and we’re on these weird plastic things that have got to taste nasty as hell. Most shark ‘attacks’ last for one bite, because the shark pretty quickly realizes that we’re not the pinniped it thought we were, and those bones aren’t worth the effort, and it leaves. Not great for the surfer who is now missing lots of bits, but hey, the shark isn’t purposefully being an asshole. It was a case of mistaken identity!

But there are lots of encounters where people don’t get hurt, right? They just get the shit scared out of them when a shark starts face-punching their arm, and panic, and call the media, and suddenly it’s an attack again. This is actually because most of a shark’s sensory organs are on it’s face.

All those red dots are organs called the ampullae of lorenzini, and they sense electrical stimulus. They’re the organs that all cartilaginous fish use to locate food – when you see a ray sweeping it’s rostrum across the sand, it’s using it’s ampullae to search for buried critters. So if a shark is curious about something, say, a human, the first response is to nose it to get more information. That’s not aggression, it’s curiosity. Then, unfortunately, if it still wants more information, it’ll go and take a nibble – because, if you look above, there are more dots right around the mouth than anywhere else. Sharks are basically the really sharp aquatic equivalent of that annoying baby who has to put everything in it’s mouth. 

Because humanity is collectively terrified of anything that has more naturally provided pointy bits than we do, everything has to demonize sharks, and that ends really badly. Everything gets interpreted as aggression. This, for instance, is a video in which a shark attempts to figure out what a pontoon boat is and gets stuck in the float. The people watching it of course put JAWS music on and captioned it as an attack, but that’s just a stressed shark going ‘wtf is this weird thing and why won’t it give me my teeth back’. 

It’s shark season, but that doesn’t mean they’re out to eat us. We’re a bony, problematic food that likes to play mean tricks by pretending to be seals. If you don’t want to get attacked by a shark? Be careful about being in the water, and don’t surf at sunset or sunrise. If you see a shark being inquisitive, just bop it. They’re not used to any sort of physical contact from something that isn’t either food, a predator, or a mate, so they’ll generally just leave immediately.

Tl;dr, sharks are mouthy babies who aren’t good at differentiating humans from seals, and we certainly don’t help them any.

Bringing this back since Shark Week is soon. 

Reblogging this because although I don’t quite agree to sharks being “mouthy babies”, I find them beautiful and fascinating and it grieves me that they’re being painted as monsters they clearly aren’t. 

Same. Sharks are amazing and beatiful creatures, but is important to remember that it is a wild animal. It should be respected and protected, not feared.

Wait, Hammerhead sharks are friendly? I had heard that they were some of the most aggressive sharks

atomic-jotunn:

gentlesharks:

Hammerheads are actually very shy. Scuba divers usually need to use food to get the hammerheads to even go near them. Like any shark, they aren’t very aggressive unless provoked.

During a shark biology course in Bimini, in May, we had a pair of great hammerheads approach us in the water* while we were snorkeling. Only one of them got close enough to concern the instructors, and it took minimal effort to stop it from making a run on a student. It did not attempt this more than once, nor did anyone get the impression that it was interested beyond simple curiosity.

*Their presence in those waters in May was remarked upon as unusual, as they usually left the waters around Bimini before then.
