Working cleanup in the wetlands of Skull Island is a team of carrion-eating invertebrates that makes a living of mopping up the remains of kills made by predators. Not too picky about what one eats means there will always be food available.
Several unique species of crabs have adapted to fulfill this role.
- Impurucaris, a small scavenger crab with paddles, giving it limited swimming abilities.
- Incultulepas, a hefty, carrion-eating true whelk that exudes a saliva that softens bone, allowing the snail to rasp away mouthfuls. Predators include Falcatops.
- Funucaris, the largest scavenger crab of the island. It grows up to 8 inches across the carapace. Strong chelae with sharp-bladed edges slice meat away from bone but can also manipulate small morsels with surprising grace and delicacy when picking the very last scraps from a skeleton.
