The ermine tail or the ermine tail cone snail ( Conus ermineus ) is a snail from the family of cone snails (genus Conus ). It is the only fish-eating conus species in the Atlantic .

features

According to Ignaz von Born's first description of Conus ermineus , “the pear-shaped red-yellow shell [...] has raised dotted stripes at the base and snow-white transverse bands. The peel is pear-shaped and smooth, striped across the bottom, and sprinkled with grains on the raised strips. The Schnirkel [the thread] is conical. The threads [whorls] smooth and somewhat flat. The color red-yellow on the curl, spotted with white, and surrounded around the body with two interrupted transverse bands. The raised points or grains are white. "

In fully grown snails, the casing can reach a length of up to 10.3 mm.

distribution

The ermine tail occurs in the Caribbean and the Atlantic coast of America, so there are finds from the USA ( Louisiana , Texas ), Mexico , Costa Rica , Colombia , Venezuela , Puerto Rico , St. Vincent and Suriname .

habitat

Ermine-tailed cone snails live on the coast up to 100 m depth.

food

As the only cone snail in the Atlantic, Conus ermineus eats fish . The prey is first harpooned with the poisonous radula tooth and then swallowed within a few seconds. Occasionally this cone snail apparently also eats cephalopods ; thus the beak of an octopus was found in the intestine of a Conus ermineus .
