Crustacean photos

Humpback whale lunge feeding on Antarctic krill, with mouth open and baleen visible. The humbpack's throat grooves are seen as its pleated throat becomes fully distended as the whale fills its mouth with krill and water. The water will be pushed out, while the baleen strains and retains the small krill.

Hermit crab. Hermit crabs wear shells to protect their soft abdomens, which are asymmetrical and curved to fit the spiral shape of their shell. Like all crabs, hermit crabs are decapods; they have five pairs of legs, including a pair of claws. One claw is much larger than the other, the hermit crab uses it for defense and food shredding while it uses the smaller claw for eating. The second and third pairs of legs help the crab walk, and the last two pairs hold the hermit crab in its shell.
