The northern kelp crab can be differentiated from similar species like the decorator crabs by its two rows of hooked setae right behind its rostrum. The northern kelp crab sometimes attaches bits of kelp and seaweed to these hooked setae to store as food for later. The northern kelp crab does not decorate its carapace as other majid crabs do. [5]
It is at its most abundant in late summer, when the canopy of the kelp forest is at its maximum, but is generally found in the higher part of the kelp understory rather than the canopy. [3] In the winter, the kelp dies back, the crab population declines and crabs may hide in rock crevices. Predators of this crab include fish, sea otters and ...
Pugettia is a genus of kelp crabs in the family Epialtidae. It comprises the following species: [1] Pugettia dalli Rathbun, 1894 – spined kelp crab [2] Pugettia elongata Yokoya, 1933 Pugettia foliata (Stimpson, 1860) Pugettia gracilis Dana, 1851 – graceful kelp crab [2] Pugettia hubbsi Garth, 1958 Pugettia incisa (De Haan, 1839)
Some animals are named after the kelp, either because they inhabit the same habitat as kelp or because they feed on kelp. These include: Northern kelp crab (Pugettia producta) and graceful kelp crab (Pugettia gracilis), Pacific coast of North America. Kelpfish (e.g., Heterosticbus rostratus, genus Gibbonsia), Pacific coast of North America.

Bateson, in a much quoted passage, [6] describes crabs of the genera Stenorhynchus and Inachus: the crab tears a piece of seaweed in its claws, chews it, and then rubs it firmly on its body until it catches on the "Velcro-like hooked setae", [1] curved hairs which permit camouflage materials to be attached.

In turn, the seaweeds and kelp conceal the Puget Sound king crab from its predators in the sky, such as pelicans and other birds that consume marine life. This is an example of a changing cycle within this community because a disturbance or change any species population could alter the rest of the community altogether.
