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 ...

Though urchins are usually the dominant herbivores, others with significant interaction strengths include seastars, isopods, kelp crabs, and herbivorous fishes. [ 10 ] [ 35 ] In many cases, these organisms feed on kelp that has been dislodged from substrate and drifts near the ocean floor rather than expend energy searching for intact thalli on ...
A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. [1] The marine environment supports many kinds of these habitats.
Cashes Ledge, a rich region of marine biodiversity, is located approximately 90-miles off the coast within the Gulf of Maine. On Ammen Rock, the shallowest area on Cashes Ledge, lies a lush kelp ...
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.
