Crinoids or Feather stars are among the most colourful and attractive species in the tropics. Looking closely, you can spot some wonderful creatures that have made them home. Shrimps, crabs, even fishes.
A Crinoid Squat Lobster (Allogalathea elegans).
A crab (cant identify the species....) raises a claw in salutation....
A Crinoid shrimp (Periclemenes cornutus)
A Featherstar clingfish (Discotrema echinophila). This is the best photo i have taken of this species. If you look closely, just bellow the gills, you will see the suction disk that is used by the fish to clink onto its host.
