The order Pennatulacea, commonly known as sea pens, are colony-forming benthos belonging within subclass Octocorallia (Anthozoa, Cnidaria). Sea pens are found worldwide from shallow to deep waters, and they are important components in sandy and muddy

A new species of the sea pen genus Scytalium Herklots, 1858, is proposed based on the morphological and molecular study of a colony collected during the Océano Profundo 2018 cruise to the Caribbean Sea (NW Atlantic). The new species, Scytalium herklotsi

Sea pens are a highly specialized and morphologically distinct group of octocorallians, but many taxa were poorly described and their phylogenetic relationships are still poorly known. We describe two species of sea pens collected from the tropical Western
