Some seals showed claws

A new study has shown that some types of seals preserved land hunting skills.

Sea lions and seals were once land and had clawed paws, like most predators. But after many years of evolution the claws is preserved only in the ordinary and harp seals, and sea lions and South American fur seals limbs are greatly shortened. Previously it was thought that this difference is not so significant, but a new study by Australian scientists showed that it is not, reports Science News.

Northern cats with claws can hunt larger prey and heavy due to the structure of their feet. In addition, it affects the type of food: claws to hold prey and to tear meat pieces, while the southern seals swallow her whole. The difference is in the consumption, production: North seals often eat it on land, not under water.
