The Prince cone or the Prince-cone snail ( Conus princeps ) is a snail from the family of cone snails (genus Conus ), which in the eastern Pacific Ocean on the coast of America from Mexico to Peru is widespread. It feeds on Vielborstern (Polychaeta).
features
Conus princeps has a medium-sized to moderately large snail shell , which in adult snails reaches 3 to 13 cm in length. The body is broadly conical, the outline straight, the shoulder angled. The low thread is covered with clear tubercles at larger intervals. The body is sculptured with spiral stripes near the base.
The basic color of the case is yellowish-brown, orange or pink, sometimes without a pattern, but mostly with irregular, mostly continuous, chestnut-brown to chocolate-brown stripes that run lengthways from the thread to the base, which can be fine and dense or wider and further apart. The inside of the case mouth is yellow or pink. The fibrous, dark brown periostracum is covered with rows of small clusters at intervals.
distribution and habitat
Conus princeps is distributed in the eastern Pacific Ocean on the coast of Central America and South America from the Gulf of California ( Mexico ) to northern Peru and the Galapagos Islands . It lives in the intertidal zone and at depths of around 30 m on rocky surfaces.
Development cycle
Like all cone snails, Conus princeps is sexually separate and the male mates with his penis . The eggs in the egg capsules develop into Veliger larvae, which eventually sink and metamorphose into crawling snails .
nutrition
Conus princeps' prey consists of poly bristles , which he pricks with his radula teeth and immobilizes with the help of poison from the poison gland .
