Krill is in fact a type of crustacean. Whales are typically animals that consume large amounts of the crustacean krill.
The insect with two prominent front claws is the male mantis shrimp, which is not actually an insect but a crustacean. However, if you're looking for actual insects, certain species of beetles, like the stag beetle, have large mandibles that can resemble claws. These adaptations help them in fighting for territory or mates.
Another name for a crustacean is shellfish. Some examples of crustaceans are crabs, crayfish, lobsters, shrimp, krill, hermit crabs, and barnacles.
Koalas do not have large claws, but they do have very strong and sharp claws.
Mantis

the large clawed iguana has large claws. the smalled clawed iguana has small claws. :)
Scorpion claws are called pedipalp.
A decapod crustacean, specifically a crab, fits this description. Crabs have ten legs, with the front pair modified into claws. The sound produced by rubbing their claws together can be interpreted as a form of singing, making them the only known singing decapods.
Crabs, and the clawlike appendages are called chilipeds.
