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 ...
Oregonia gracilis, commonly known as the graceful decorator crab, is a species of crab belonging to the family Oregoniidae. [3] Like other decorator crabs it habitually attaches other organisms to its back. [4] The sessile organisms are attached to hooked setae that act as a sort of velcro attachment.

When fleeing a predator on a sloping substrate or while crawling on kelp, a Norrisia norrisii may simply detach itself and roll or fall away from the predator. If detached from a giant kelp or other stipitate alga, Norrisia norrisii will quickly crawl towards another kelp upon reaching the bottom.
Membranipora membranacea colonies consist of individual organisms called zooids, each with a chitinous exoskeleton which is secreted by the epidermis. [6] This exoskeleton, hardened with calcium carbonate, is known as the zooecium, which not only serves to protect the internal structures of the organism, but also keeps the individual permanently attached to the substrate and neighboring zooids ...
The profitability of kelp harvesting meant that landlords began to subdivide their land for small tenant kelpers, who could now afford higher rent than their gentleman farmer counterparts. [55] But the economic collapse of the kelp industry in northern Scotland during the 1820s led to further emigration, especially to North America. [citation ...
