Natural Habitat

Diet & Feeding

Scavenger; primarily feeds on decaying seaweed (kelp) and other organic debris washed ashore by the tide.

Behavior Patterns

They are nocturnal to avoid predators and desiccation, and are known for their ability to jump long distances by suddenly extending their abdomens. They spend most of the daylight hours buried in moist sand.

Risks & Benefits

They pose no risk to humans as they do not bite or sting. They are beneficial to the ecosystem as primary decomposers of beach wrack and serve as a vital food source for shorebirds.
