Button Tunicate

Distaplia corolla

Button Tunicates are colonial organisms that typically reach a maximum size of 10.0 cm. They are often found on coral reefs, particularly on lateral or overhang surfaces, and are commonly seen on mangrove roots. Their sessile nature means they remain fixed in one place, making them distinctive in their habitat. The colonies can be recognized by their button-like appearance, which sets them apart from other tunicates that may have different forms or structures. These tunicates thrive in tropical environments and are primarily distributed across the Atlantic Ocean. They are often located in shallow waters, typically associated with coral reefs, which provide a suitable substrate for their growth. Their life cycle includes a larval stage that develops into benthic adults, and they are known to reproduce through both cross- and self-fertilization, which is typical of hermaphroditic species. Divers may encounter Button Tunicates while exploring coral reefs, where they can observe the colonies attached to various surfaces. The presence of these tunicates adds to the biodiversity of the reef ecosystem, and although they are not evaluated for conservation status, their habitat is crucial for their survival. Observing these organisms can provide insight into the health of coral reef environments.
