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]
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.

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)
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 ...
Frequently considered an ecosystem engineer, kelp provides a physical substrate and habitat for kelp forest communities. [50] In algae (Kingdom: Protista), the body of an individual organism is known as a thallus rather than as a plant (Kingdom: Plantae). The morphological structure of a kelp thallus is defined by three basic structural units: [49]
The definition of the trophic level, TL, for any consumer species is [6] = + (), where is the fractional trophic level of the prey j, and represents the fraction of j in the diet of i. In the case of marine ecosystems, the trophic level of most fish and other marine consumers takes value between 2.0 and 5.0.
