📖 Overview

Apparently invariably associated with a (Polycarpa sp.) on silty-sand bottoms. which was common between about 13-30 m, but only populated by fishes below a depth of about 20 m. About a third of the tunicates below 20 m were estimated to be occupied by fish, solitary or in pairs. The fish were usually observed perched on the lip of the tunicate’s oral or incurrent siphon, retreating quickly inside when disturbed and also made brief forays on the exterior part of the tunicate and around its base .
