Pilsbry’s Headshield Slug: The Black & White Sea Slug That’s Not a Nudibranch
The Pilsbry’s Headshield Slug, Tubulophilinopsis pilsbryi, is often misidentified as a nudibranch but belongs to the Cephalaspidea order. This carnivorous sea slug uses its broad head shield to hunt prey in sandy sediments. Found in the Indo-Pacific, it’s distinguished by its variable black and white coloration, making sightings rare and exciting.
