Leather Bryozoan

Flustrellidra corniculata

Flustrellidra corniculata is a sessile organism found in temperate waters, particularly in the Northeast Pacific region, including Canada. This species typically inhabits shallow environments, with recorded depths generally shallower than 40 meters, and 90% of occurrences noted at depths of about 10 meters or less. The leather bryozoan can often be found on hard substrates, such as rocks and other marine structures, where it forms colonies that can be identified by their leathery texture and branching structures. These colonies can be mistaken for other bryozoans, but their distinct shape and texture help in identification. As a hermaphroditic species, Flustrellidra corniculata has a unique reproductive strategy that may involve both internal and external fertilization. The specifics of its breeding behavior, including spawning and egg brooding, are not detailed, but it is known that members of the Bryozoa phylum generally exhibit varied reproductive methods. Encounters with this species during dives can be interesting as divers may observe its colonies clinging to underwater surfaces, providing a glimpse into the biodiversity of the marine ecosystem. The conservation status of Flustrellidra corniculata is currently not evaluated, indicating that there is insufficient data to assess its population trends or threats. Divers should approach this species with care, as it contributes to the overall health of its habitat by participating in the marine food web.
