It sometimes employs fragments of kelp as decoration, but not to the extent of the graceful decorator crab (Oregonia gracilis). 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]
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)
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.
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]
The graceful decorator crab, Oregonia gracilis Decorator crabs are crabs of several different species, belonging to the superfamily Majoidea (not all of which are decorators), that use materials from their environment to hide from, or ward off, predators.
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.
