Description

Tambja olivaria is characterised by its dull 'olive' green background colour and pattern of black and orange-yellow markings. The black and yellow pattern is quite variable but its major elements consist of a yellow band that runs a round the anterior end, just in from the dark green edge, then runs back on each side to join behind the gills. Parts of this band can be absent, and at the posterior end, the join behind the gills it forms quite an acute angle. There are a pair of black patches just behind the rhinophores. The raised rhinophore pocket is yellow with a black border. The rhinophore club is black. The gills are yellow on the outer face with black lamellae. There are traces of a yellow submarginal band around the edge of the foot.
