The crabeater seal sometimes gathers together in large groups for protection. Young pups in particular will congregate in groups of up to a thousand individuals.

When ice packs start to melt, they may travel long distances to seek refuge elsewhere.
What is the scientific name for a crabeater seal?

What are the predators of crabeaters?
Seals are quite exposed in the water and risk being eaten. If the seal manages to escape from their grasp by climbing on ice, then packs of orcas may attempt to tip over the ice by creating waves in the water.

Many adults still carry scars that testify to the seriousness of these attacks.
