Using stinging tentacles and wide mouths, large coral polyps in the Red Sea have, for the first time, been discovered eating jellyfish nearly as big as they are.

A "saber-toothed cat in armor" and a pancake-shaped predator are among five strange, dinosaur-era crocodile cousins discovered in the Sahara, archaeologists say. Meet BoarCroc, PancakeCroc, DuckCroc, RatCroc, and DogCroc.
