Phallusia fumigata

Phallusia fumigata is a tunicate characterized by its sessile lifestyle, typically found in temperate regions. This species inhabits the Northeast Atlantic and the Mediterranean, including areas like Scotland. It is often located on rocky substrates or similar environments, thriving in depths that are not specifically detailed in the sources. Divers may encounter this species attached to surfaces, blending in with its surroundings, which can make it challenging to spot among other marine life. As a hermaphroditic organism, Phallusia fumigata can reproduce through both cross- and self-fertilization. The life cycle begins with eggs that develop into lecithotrophic larvae, which eventually metamorphose into benthic adults. This reproductive strategy contributes to its distribution across various marine ecosystems, although specific details on its breeding habits are not provided. During a dive, encountering Phallusia fumigata can be a subtle experience, as it does not exhibit active swimming behavior. Instead, it remains stationary, filtering food from the surrounding water. The conservation status of this species has not been evaluated, indicating a lack of comprehensive data on its population dynamics and threats.
