Type species
This is the type species (holotype) of the genus Pikea.

Status of name

Origin of species name
Adjective A (Latin), pertaining to California (Stearn 1973).

Eponomy
The genus was named for "Capt. Nicholas Pike of Brooklyn", who collected the type.

Synonym(s)
No synonyms are currently included in AlgaeBase.

Distributional notes
Pikea californica was first recognised on the Isles of Scilly off south-west England in 1983, although examination of herbarium specimens showed that the population was present in 1967 (Maggs & Guiry 1987). This species is known from the west coast of North America. It is thought to have been introduced from California (Maggs & Guiry 1987), possibly having arrived during World War II. Flying boats flew directly from California to the Isles of Scilly during World War II and seaplane hulls and floats are occasionally fouled by algae. This species may have been transferred by flying boats employing canvas sea anchors (stored in the hull while flying which would consequently have been damp but aerated)(Maggs & Guiry 1987). However, Maggs & Ward (1996) have carried out a survey of the Californian coast and reported that this species does not currently occur around San Diego, where the seaplanes were manufactured. They have no other suggestions concerning the vector used for transporting this species from California, but shellfish importations should also be suspected, perhaps from Japan.

According to Boo et al. (2016), the previous report of P. californica in Korea is a misidentification. - (23 Feb 2016) - Wendy Guiry

Habitat notes
low and mid intertidal; tide pool; epilithic (Augyte & Shaughnessy, 2014). - (8 Dec 2014) - Wendy Guiry

General environment
This is a marine species.
