Phyllidiopsis shireenae -Facts and Photographs

 

Phyllidiopsis shireenaeThe Phyllidiopsis shireenae is a species of colourful sea slug. They are dorid nudibranchs, marine gastropod mollusks. They were first described in 1993 by Brunckhorst.

APPEARANCE

Phyllidiopsis shireenae have an elongated shape and a prominent dorsal crest. Around the visceral hump is a black band. In this specimen there are six black lines that diverge from the black band. One each to the anterior and posterior not quite reaching the mantle and two on either side that go down to the mantle. Some specimens such as this one have random small black markings. The rhinophores are pale salmon pink. This specimen was photographed on Big T reef off Dar es Salaam in Tanzania at around 20 meters. This specimen was approximately 110 mm in length. They are usually either a pale pink, blue or grey in colour.

IN THE WILD

The Phyllidiopsis shireenae are not that common in Tanzania but are very occasionally seen on the top of some reefs at about 15 to 18 meters in depth. They have  the ability to secrete toxic substances which provides protection against predators. Being fairly slow moving they are easy to observe while diving. They seem to sense a diver and usually head for cover, probably not appreciating having lights shone on them.

 

HABITAT

The Phyllidiopsis shireenae is found across the Indo west Pacific area . They are found on rocky and coral reefs to a depth of 30 meters.

REPRODUCTION

They are simultaneous hermaphrodites and mating takes place by darting. The individual who darts the other first becomes the dominant male and the other the female. Eggs are laid on a solid substrate and when they hatch the larvae become planktonic before growing into adults.
