nudibranch Jorunna funebris Family Kentodoridae/Dorididae updated Jan 09 Where seen? This distinctive elegantly-spotted nudibranch is regularly encountered on many our shores. Sometimes lots are seen. On coral rubble near reefs. Features: 1- 6cm long. Fleshy oval body, white with black circular markings. These markings are actually made up of tiny raised black bristles on the skin (called caryophyllidia). It has black-tipped rhinophores and black edging on feathery gills on the back. What does it eat? It is said to eat a blue sponge (Haliclona sp.). Indeed, on Pulau Sekudu, we often see large Polka-dot jorunna nudibranchs near these sponges, sometimes in pairs, and sometimes appearing to have just having laid a ribbon-like egg mass. |
