four. Crocodiles have fairly weak jaw opening muscles, which may be held shut with merely a rubber band, or your bare arms.
The special properties and fossil document implies a instead specialised diet before, preying on megafauna like the read more big sloth. This species occasionally displays pack-looking behaviour, which might are The important thing to searching substantial species previously, Irrespective of its small measurement.[fifty one] Now most prey are small to medium sized vertebrates. It really is Critically Endangered, plus the remaining wild populace is less than threat of hybridization.[52]
Although this crocodile species goes from the name saltwater, their Main habitat is freshwater brackish swamps, estuaries, and rivers. However, they are also able to survive in salt water, spending times or even months in swimming and drifting quite a few kilometers And maybe to prey en route.
Crocodiles have essentially the most acidic abdomen of any vertebrate. They can easily digest bones, hooves and horns.

Nonetheless, the species was lately split just after researchers seen some noticeable variances inside the skull of the new species.
