Cyerce bourbonica Yonow, 2012
Maximum size: 10 mm (Scott
Johnson).
Identification:
The is a cream animal with brown pigment on its notum and brown
reticulation on it's rhinophores. The cerata are roughly
diamond-shaped and tuberculate with dark pigment basally and a margin
decorated with orange and violet spots.
Natural history:
Cyerce bourbonica
is a
moderately rare species found in protected to exposed rocky habitats
and Halimeda kanaloana beds
at depths of < 1 to 6 m (< 3 to 20 ft). It jerks its cerata
intermittently while
crawling and can also swim, if disturbed, by arching its body and
flapping its cerata up and down. That makes it look very much like a
small jellyfish "pulsing" through the water. (see photos) It lays a spiral,
cream egg
mass that hatches in about four days in the laboratory.
Distribution:
Big Island, Maui, Oahu and Kauai: widely distributed in the Indo-Pacific.
Taxonomic notes:
The species was first recorded in Hawaii at Kewalo Reef, Oahu by Scott Johnson on April
14, 1978. It was named for Bourbon, the original name of the island of
La Réunion, the type locality.
