Shellmon is a Sea Animal Digimon. It is a hermit crab-like Digimon that lives in the margins of the "Net Ocean". Although it has a turtle-like appearance when its settled inside its shell, for all intents and purposes it has a soft body like a mollusk. Because its body rapidly gets bigger as it grows, it replaces its home each time until it reaches the size of a small mountain. Also, if its body can fit all the way in, it has a habit of settling in completely. Since it has low intelligence and a belligerent personality, you must be careful if you come across a Shellmon.[2] Sangomon use the backs of Shellmon as a resting place.[3] It is a companion of MoriShellmon.[4]

Shellmon is a turtle-like mollusk Digimon with a gray turban shell. It is pink with blue spots and has green anemone tendrils on its head and sucker-like fingertips on its hands. It has blue eyes and its mouth consists of interlocking lips.
