# Botrylloides

Botrylloides is a genus of ascidian tunicates in the family Styelidae.

## Description

Like Botryllus, Botrylloides are flat sheets of organisms which can be found covering ropes, boat hulls, horseshoe crabs, seaweeds, and any still or slow-moving object in saltwater. Also both are considered to be invasive, found in many ports around the world. Invasive tunicates such as these, Didemnum sp., and Styela clava are a problem for shellfish and other marine life populations, and cause fouling of boats and piers.
