The Java turrets ( Turricula javana , original combination : Surcula javana ) is a snail from the family of the leg worm , which in the Indo-Pacific is widespread and polychaete (Polychaeta) eats.
features
The snail shell of Turricula javana reaches a length of about 3.5 to 7.5 cm in adult snails, often 6 cm. The whorls are angled and occupied in the middle with tubercles, which develop from more or less indistinct, oblique folds or ribs and are surrounded by fine stripes. The surface of the shell is light yellowish-brown, the tubercles lighter.
distribution and habitat
Turricula javana is distributed in the Indo-Pacific from the coasts of East Africa , Pakistan , India and Sri Lanka via Indonesia to Australia ( Queensland ), Vietnam , the South China Sea , the Philippines and Japan . It lives below the intertidal zone down to a depth of about 30 m on muddy surfaces.
Development cycle
Like all leg snails, Turricula javana is separate sexes. The Veliger larvae swim free before they sink and metamorphose into crawling snails .
nutrition
Turricula javana feeds on sedentary Vielborstern (Polychaeta), in particular from the genera Poecilochaetus and Marphysa .
