Mammalia

Ancestor of all placental mammals was an insect eater

Placental mammals were early insectivores and lived along with dinosaurs in the Late cretaceous. During cretaceous mass extinction, dinosaurs became extinct and opened up lots of dietary niches. The ancestral insectivore radiated out into all the niches and had 5 chitinase genes. But those who got adapted for other diets lost their chitinase genes through accumulation of various mutations. These gene remnants passed on to all mammals now exist, as pseudo genes.

Mantis Shrimp

Mantis shrimps are called "sea locusts" by ancient Assyrians, "prawn killers" in Australia and now sometimes as "thumb splitters" – because of the animal's ability to inflict painful gashes if handled incautiously. These animals sport powerful claws that are used to attack and kill prey by spearing, stunning, or dismembering. In captivity, some larger species can break through aquarium glass.
