Very special thanks for the first photo of Coralliocaris graminea to Sonja Ooms!
The photo was taken on 7 December 2013 during a night dive. The location was Pulau Abadi, Lembeh Strait, Manado, North Sulawesi, Indonesia.
Coralliocaris graminea is a tiny commensal shrimp very difficult to see, it lives amongst the branches of Acropora hard corals. Distinctive colour pattern, with white, green and brown longitudinal lines. 1 cm. Other commensal shrimps share the same environment, but the colour pattern of this one is unique and distinctive.
