Seals are streamlined to reduce the friction between it and the water around it, this allows the seal to dive. Streamlining also allows the seal to move faster through the water and change direction quickly to escape from predators or to hunt prey.
They were seals.
So they can swim faster (;
Seals evolved these features to become more hydrodynamic.
Animals like octopus , squid andstarfish have streamline bodies.
Blubber is fat. THeir bodies will make it, just like our bodies, if they get enough to eat.
Since penguins cannot fly, they have adapted to have streamline bodies to swim in their environment.
To make them more streamlined for faster swimming.
by the fat on the bodies and food and water
Seals have a thick layer of fat around their bodies, plus oily, waterproof fur to help insulate them.
Whales and Seals have a layer of fat under their skins which act as an insulator/prevent heat loss from their bodies
I think so
They kill seals because of their fur and some times because of their meat. Some people kill them and use all part of their bodies though
