Botrylloides perspicuus

Botrylloides perspicuus is a colonial tunicate that can be found in the Indo-Pacific and Western Central Atlantic regions. It typically inhabits depths ranging from 7 to 170 meters, although most recorded occurrences are shallower than 40 meters, with 90% found at depths around 20 meters or less. This species is sessile, meaning it attaches itself to substrates in its environment, which can include rocky reefs and other hard surfaces. Its colonial nature allows it to form large aggregations, making it a notable sight for divers exploring these depths. The appearance of Botrylloides perspicuus can vary, but it generally presents a leathery texture with a range of colors. Divers may find it difficult to distinguish this species from other similar tunicates, but its colonial structure is a key identifying feature. The species is hermaphroditic, engaging in both cross- and self-fertilization, which aids in its reproduction. The life cycle involves eggs developing into lecithotrophic larvae before they metamorphose into benthic adults, contributing to the colony. When encountered during a dive, divers may observe the colonies clinging to rocks or other surfaces, often in clusters. The species does not pose any threat to humans, and its presence can indicate a healthy marine ecosystem. Conservation status for Botrylloides perspicuus is not evaluated, leaving its population dynamics uncertain. However, its widespread distribution across multiple dive sites suggests it is relatively common in suitable habitats.
