Pygmaeconus visseri
Pygmaeconus visseri is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies. The species is named for J. S. de Visser, who originally collected the specimen.
Like all species within the genus Conus, these snails are predatory and venomous. They are capable of stinging humans, therefore live ones should be handled carefully or not at all.
