Abstract

A new species of Pachycerianthus(Cnidaria: Ceriantharia) is described from the Brazilian coast of the southwestern Atlantic Ocean. Pachycerianthus schlenzae sp. nov. is found in fine sand or mud in shallow waters of Abrolhos and Royal Charlotte Bank. The new species is only known from this area and is most notably different from other species of the genus Pachycerianthus in mesentery arrangement and cnidome. In addition to the description, we provide some biological data collected from individuals cultivated under laboratory conditions.

The full open-access paper can be read here.

A close-up of the unique mesenteries and cnidome (array of nematocysts) that define this new species.  This is the stuff that makes fish disappear at night and make you say ouch.
