This relatively small elongate Sea Hare usually has dark longitudinal lines and scattered eye spots, either with pink or blue centres.
During any month of the year (though more commonly in spring/summer), when populations are high, it can form vast "locust-like" swarms that migrate across the bottom stripping the substrate of cyanophytes as they advance. (Note 1) When food is exhausted, entire populations may release from the bottom and drift off on the current with the animals using mucous.. more
