Felimida krohni (=Chromodoris krohni) is a small dorid
nudibranch with a bluish-green base colour with diffused
greenish discontinuous lines (3 main, 2 minor in between)
and a yellow or yellow/orange sub-marginal band.
Oral tentacles: 2 in number, short, pale blue coloured. Rhinophores: Pale blue-green with blue tips, lamellate,
retractile. Gills: Present, unipinnate, pale blue near base but with
darker tips. Foot: Pale blue with white to green lines or spots
particularly at the posterior edge.
Size range: 11-20mm. Uncommon.
Specific characteristics: This species is easy to
distinguish from related species by its colouration;
however it may be superficially confused with F. britoi
which has yellow lines and violet colour, or with villafranca
which has white and yellow disconnected lines and a
bluish body colour.
