Green gum drops ascidians
awaiting identification*
updated Jan 12

Where seen? These little ascidians that resemble green sweets are commonly seen, especially on our Southern shores.

Features: Each blob about 1cm long. Flat, irregular shapes with rounded margins so that each shape resembles a gum drop. Each shape appears to be made up of many individual zooids embedded in a common tissue. The shapes are arranged higgledy-piggledy in crowded clusters on seagrasses such as Tape seagrass (Enhalus acoroides), seaweeds as well as on coral rubble.

It's hard to identify ascidians without close examination of small features. On this website, they are grouped by large external features for convenience of display.
