Observations of Modified Polyps and Polyp Leaves in Sea Pens (Cnidaria: Octocorallia): The Cases of <i>Ptilella</i> and <i>Pennatula</i>. [PDF]
Ecol EvolWe describe unusual and mostly unreported morphological traits on colonies of the deep‐water sea pens Ptilella and Pennatula from the Northwest Atlantic, namely the presence of hypertrophied polyps, split polyp leaves, and autozooids budding on the surface of polyp leaves (as opposed to the edges). ABSTRACT Here we describe unusual morphological traits
