Nudibranch (chromodoris)
Chromodoris annae
Sighting evidence at Kendwa Reef, Zanzibar Island
Kendwa's terrace hosts one of the highest nudibranch diversities on the main island, with chromodorid species being the most reliably found — their vivid blue, black and white banding being a textbook example of aposematic warning colouration advertising the toxins sequestered from their sponge diet. Nudibranchs are simultaneous hermaphrodites that mate by aligning parallel with each other, and egg masses laid on sponge surfaces are common at Kendwa between December and March. Over 30 nudibranch species have been recorded at this single site.
