Umbellula encrinus Linnaeus, 1758 is a deep-water sea pen commonly found in the Eastern Canadian Arctic. It can reach heights of >2 m, and it has often been caught as fishing bycatch. Here we characterized abundance/density, size metrics, longevity, and growth rates of U. encrinus colonies from Baffin Bay (between Greenland and Canada). No prevalent size classes were identified at most locations, except for Jones Sound and Cape Dyer, where small-size colonies dominated. Average number of growth rings in the internal skeleton (axis) of the examined colonies ranged between 2-68, with a maximum of 75.
