The warty frog snail ( Bursa bufonia ) is a medium-sized predatory living snail from the family of the frog snails , which in the Red Sea and the Indo-Pacific is widespread.
features
The thick-walled, solid snail shell of Bursa bufonia , about 5 cm high, sometimes over 7 cm high, is compressed dorsally and ventrally and has a number of varices on each side. The outer surface of the house is sculptured with fine threads made from nodules. On the shoulder of the raised thread runs a row, on the circumference of the body three rows of humps, of which the first row is the strongest. The house is cream colored with small reddish brown spots on the spiral ridges. The case mouth is almost circular and yellow inside. The outer lip of the housing mouth is flared and has 4 to 5 pairs of teeth on its edge. The inner lip is thick and flared, the umbilicus covered, the siphonal canal short and curved, the anal canal long and semi-tubular.
distribution and habitat
Bursa bufonia is widespread in the Red Sea and the Indian Ocean from Madagascar , Aldabra , Chagos and the Mascarene Islands to the western Pacific Ocean , here from Japan and Hawaii to Queensland . The snail is found mainly on coral reefs in the intertidal zone and a little below it down to depths of about 20 m.
Life cycle
Like other frog snails , Bursa bufonia is separate sexes. The male mates with the female with his penis . Veliger larvae hatch from the eggs and live as plankton until they have metamorphosed into the finished snail.
food
Bursa bufonia feeds on sea urchins .
