The Babylonian screw auger ( Terebra babylonia ) is a snail from the family of the screw worm , which in the western Pacific Ocean is widespread and polychaete (Polychaeta) eats.
features
Terebra babylonia has a long and slender, tapering snail shell with barely rounded edges, which in adult snails reaches about 4.5 cm in length and 7 mm in length. Below the seam runs a band with two rows, later a row of elongated pearls, delimited by a deep, spiraling groove. The thread is sculptured with axial strips. The Protoconch consists of three and a half conical, slightly convex passages with a notched seam. The case mouth is egg-shaped, the spindle is folded. The case is flesh-colored with orange-brown stripes, a white band along the seam and an orange-brown case mouth.
distribution and habitat
Terebra babylonia is distributed in the Indo-Pacific from the Persian Gulf via China and Fiji to Polynesia and Micronesia from the shore to a depth of about 200 m.
Development cycle
Like all snails, Terebra babylonia is sexually separate, and the male mates with his penis . The Veliger larvae swim free before they sink and metamorphose into crawling snails .
nutrition
Terebra babylonia feeds on Vielborstern (Polychaeta). The prey animals are stung with radula teeth and poisoned with the help of the poison gland .
