The crocodile newt, also known as the mandarin salamander (Tylototriton verrucosus), is lined and dotted with bright orange markings that let other animals know not to eat it. When attacked, glands in the crocodile newt’s skin exude a distasteful secretion. Typically land-dwelling and nocturnal, this amphibian hunts at night for invertebrates. During monsoon season, they migrate to breeding ponds to lay their eggs before returning to their terrestrial environments.

The Chinese crocodile lizard (Shinisaurus crocodilurus) is only found in a small area of eastern Asia. These little reptiles can be very difficult to spot due to the fact that they can freeze midstride for hours at a time to escape detection. Because its coloring acts as good camouflage, becoming motionless for periods of time render it almost invisible. It also has an interesting way to survive lower temperatures: it is able to shut down its internal system to conserve energy during particularly cold nights.

Known as the saltwater crocodile, estuarine or Indo-Pacific crocodile (Crocodylus porosus), this formidable predator is the world’s largest reptile, and is also one of the few crocodilians that frequently swims out to sea. Its power and ferocity are legendary, and it is thought to be responsible for more than 1,000 human deaths per year. The saltwater crocodile has powerful jaws housing teeth up to 13 cm long. Its immensely tough skin is covered with thick scales. The scales on its back are armored with bony deposits called osteoderms, while its tail has a double row of upright bony plates (scutes). Its nostrils close when it dives, but it cannot exclude water from its mouth. Instead, it has a valve at the entrance to its throat, which opens only when it swallows food.
It controls its body temperature by cooling down in water and warming up in the sun. Like other large crocodiles, the saltwater crocodile hunts by stealth, lurking close tot he shore, hiding beneath the water with little more than its eyes and nose visible. When an animal comes within range, it bursts out of the water with explosive force, grabs its victim, and then drags it under until it drowsn. Crocodiles cannot chew their food—instead, they tear it to pieces, digesting scales, skin, and even bones. Their natural prey includes birds, fish, turtles, and a wide variety of mammals, such as wild boar, monkeys, horses, and water buffalo. Females lay up to 90 eggs in a waterside mound, carrying their young to the water when they hatch. Saltwater crocodiles are hunted in many parts of their range, making large specimens rarer than they once were.

Blame it on the AMNH.  Known as the saltwater crocodile, estuarine or Indo-Pacific crocodile (Crocodylus porosus), this formidable predator is the world’s largest reptile, and is also one of the few crocodilians that frequently swims out to sea.

Crocodile Icefish

These ghostly Antarctic predators are unusual because their transparent appearance is due in large part to nearly invisible blood. They are the only known vertebrates in the world without hemoglobin, the protein in blood that transports oxygen.
 
They survive without hemoglobin thanks to the subzero temperatures of the ocean where they live, since cold water has a much higher dissolved oxygen content than warmer water.

I am Ashley, an incredibly introverted 21-year-old environmental enthusiast.
I'm studying to be a marine biologist, but I live near the Great Lakes rather than the ocean.
I have a fierce love for all living things, a very broad sense of humor, and I'm probably too passionate for my own good.
Herein you'll find animals (especially creepy-crawlies), nature, science, art, some of my own photography, and probably more things about my personal life than you would care to know.
I'm an avid reader and music-listener, so suggestions are always welcome (you can check out my last.fm if you're interested).
I source all of my own posts unless it's my content, in which case I tag it "personal."
But that tag is littered with a bunch of other things as well, so peruse with caution.
