The carrot-cone snail or carrots cone ( Conus daucus ) is a snail from the family of cone snails (genus Conus ), which in the western Atlantic Ocean and Caribbean Sea is common and from Vielborstern malnourished.
features
Conus durcus bears a broad, conical, moderately heavy snail shell with convex, then straight and tapering sides, which in adult snails reaches from 2 to 6.6 cm in length. The base of the body is covered with 12 ribs and threads. The shoulder is broad, angled to keeled and slightly concave at the top. The tapered thread is low to shallow, the sides deeply concave. The spindle is short. The surface of the housing is similar to a carrot, light orange to reddish, occasionally shaded yellow, often with many, spaced rows of small brown, square dots. There are sometimes indistinct white spots on the shoulder. The base, like the apex, is paler with a tendency to pink. A pale, sometimes interrupted band often runs in the middle. The thread is sometimes mottled pale chestnut. The case mouth is purple to pink or orange, the outer edge sometimes reddish-brown.
The radula teeth connected to a poison gland are about 2 to 3% as long as the snail shell. They have a single, protruding barb, which makes up about 7 to 9% of the total tooth length, and long, strong teeth.
The body is usually the same color as the housing, i.e. usually light orange to orange-red. The top of the foot, the rostrum and the siphon are orange to dull red.
distribution and habitat
Conus durcus occurs in the western Atlantic Ocean , the Caribbean Sea , the Gulf of Mexico , on the northern Mid-Atlantic Ridge , in the Red Sea and in the Indian Ocean as far as the Mascarene Islands from the intertidal zone to a depth of 120 m, preferably 1 to 20 m.
Diet and predators
The prey of Conus daucus consists of Vielborstern (Polychaeta).
Conus durcus is eaten by mantis shrimp and octopus .
