A good meal can go a long way!
Given crocs are ectothermic, they don’t need to eat everyday. And if they take down large prey, they can be satisfied for up to 3 weeks. Even in the wild they can go months without food as long as they have good fat reserves.

On the 10th day of CROCmas… Living amongst wetlands and freshwater ecosystems in Venezuela, the Orinoco croc loves to bite down on a nice size crab. A nice crab dish for the holidays would be Rompe Colchón, a local dish that includes sautéed garlic or onion, served over rice or plantains.

On the 8th day of CROCmas… The Papa New Guinea croc (Crocodylus novaeguineae) inhabits freshwater swamps and marshes, in which it encounters various aquatic prey. A fav prey dish for this holiday season would be one of crab (and if they could, they could make it into a Christmas Crab dish

Crocs don’t chew, so they use other means to tenderize and tear their food

This croc was attacking dogs given its relatively easy prey for its poor eyesight. But the croc isn’t the problem, people are. Water pollution is causing eyesight issues & people feeding the croc created a perfect storm of conflict.

While the closing force of crocodilian jaws can be >3000 psi, the muscles that open the jaw are much weaker, so all you have to do is just reach out & pinch them shut.
Now hold the jaw shut until... uh... just HOLD it okay? Until I get over the next ridge. To, uh... get help. 🐊

Crocodylians are unique relative to other animals as they have a 4 chambered that can convert to a 3 chambered heart. And that my friends, is some cool and #weirdscience

Oh so you have a PhD in biology studying crocodilians? You wrestle them like in Swamp People?
Oh you have a Ph.D. in marine biology? So are you like a dolphin trainer at sea world?
What’s the worst question someone can ask after you tell them your profession? For linguists, it’s definitely “how many languages do you speak?”, but I’m curious what else is happening to the rest of y’all out there?!

It's December. The goal is to find MELIA a home for Christmas. We can do this. Over 810 days waiting. Poor baby. A quiet adult only home, no dogs, cats are ok. 3.5 years old, around 50 lbs. Come on New York!

These species are facing increasing pressures. Strong international safeguards are essential to their survival.
