Bull kelp

Last updated

Bull kelp is a common name for the brown alga Nereocystis luetkeana [1] [2] which is a true kelp in the family Laminariaceae. It grows in rough-and-tumble coastal waters. [3] It ranges from Unimak Island, Alaska, and California, but there is more of it north of San Francisco. [2]

Species in the genus Durvillaea are also sometimes called "bull kelp", but this is just a shortening of the common name southern bull kelp. Durvillaea is a genus in the order Fucales and, though superficially similar in appearance, is not a true kelp (all of which are in the order Laminariales).
