The Royal cone or the Crown cone snail ( Conus regius ) is a snail from the family of cone snails (genus Conus ), which in the western Atlantic Ocean and Caribbean Sea is common. It prefers to feed on fire bristle worms .
features
Conus regius has a large, cone-shaped snail shell , which in adult snails reaches 7.5 cm in length and has a straight outline. The thread is low and has pronounced tubercles at intervals, which give the case a crown-like shape. At the base, the body is sculptured with light stripes. The surface of the shell is mostly chestnut brown with blue-white spots, although there are also white, yellow-brown and pale brown variations. The inside of the case mouth is white, sometimes with maroon spots.
distribution and habitat
Conus regius occurs in the western Atlantic Ocean , Caribbean Sea and Gulf of Mexico to the coast of Brazil . It prefers sea depths of up to 95 m.
food
The prey of Conus regius consists of Vielborstern (Polychaeta), in particular highly toxic, fortified and predatory fire polychaetes (Amphinomidae) that it with its toxic Radulazähnen harpoons and eats. It is described as more aggressive than Conus aurantius because, in contrast to this, it actively seeks out its prey and not just waits for them to come by.
