Sea otters are significant predators of the northern kelp crab within kelp forests. As pelagic larvae they are eaten by Velella velella or the by-the-wind sailor. [4] The northern kelp crab can be parasitized by Heterosaccus californicus (rhizocephalan sacculinid barnacle) which exhibits a brown mass extending from the crab's underbelly.
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.
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are a part of the subphylum Crustacea (/ k r ə ˈ s t eɪ ʃ ə /), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp ...
A curious sea creature stalked a team of divers through a giant kelp forest in California, and even decided to nibble on one of their wetsuits.
When the sea otters of the North American west coast were hunted commercially for their fur, their numbers fell to such low levels that they were unable to control the sea urchin population. The urchins in turn grazed the holdfasts of kelp so heavily that the kelp forests largely disappeared, along with all the species that depended on them.
