Conus abbreviatus is a marine snail that is found in the seas off Hawaii . Like all members of the genus Conus , Conus abbreviatus livespredatory and kills its victims - bristle worms - with poison . Conus abbreviatus was first described by Lovell Augustus Reeve in 1843.
description
The height of the conical housing varies and is approx. 30 mm. Slight reticulated furrows can be seen on the shell. The color of the shell is light blue with dark brown dots at regular intervals. The points in Conus abbreviatus are similar to those in Conus miliaris , but are evenly distributed over the surface.
Since Conus abbreviatus can also be toxic to humans, living specimens should be handled with extreme caution.
distribution and habitat
Conus abbreviatus lives on the Hawaiian Islands in the intertidal zone and below it to a depth of about 15 m, exceptionally up to 100 m. It lives mainly on sand and algae lawns on limestone subsoil.
Development cycle
Like all cone snails, Conus abbreviatus is sexually separate and the male mates with the female with his penis . The female lays capsules about 9 to 10 mm long and 7 to 9 mm wide under rocks in parallel rows on basal plates on a solid substrate. One capsule contains about 1300 eggs, a whole clutch about 44,000 eggs. The eggs inside are around 160 to 180 µm in size and develop into free-swimming Veliger larvae. According to observations in Hawaii, the plankton phase of the larvae lasts about 32 days before they sink and metamorphose into crawling snails .
nutrition
Conus abbreviatus eats polychaete (Polychaeta), wherein the Euniciden Eunice antennata prefers as prey, but also the nereids Perinereis helleri eats.
