The Granular cone snail ( Conus granulatus ) is a snail from the family of cone snails (genus Conus ), which in the western Atlantic Ocean is widespread. It feeds on many bristles and small fish .
features
Conus granulatus has a medium-sized snail shell , which in adult snails reaches 6 to 8 cm in length. The circumference of the body is covered with regular grooves, between which the surface is flat or granular. The thread is sculptured with stripes and often graduated. The surface of the case is orange-red, raised areas with very narrow auburn spiral lines, white cloudy pattern, especially in the middle, and thus forming an irregular band with auburn spots and edges. The inside of the case mouth is pink.
distribution and habitat
Conus granulatus is common in the western Atlantic Ocean , the Caribbean Sea, and the Gulf of Mexico . It lives from the shore to a depth of about 30 m.
Development cycle
Like all cone snails, Conus granulatus is sexually separate, and the male mates with the female with his penis . The eggs in the egg shell develop into Veliger larvae, which after a free-swimming phase sink down and metamorphose into crawling snails .
nutrition
The prey of Conus granulatus consists predominantly of poly-bristles , but occasionally it also eats fish , which it harpooned with its poisonous radula teeth . Both a puffer fish and a nereid were found from one individual .
