UPDATED: Caribbean coral species identification tool
There have also been some updates on the coral ID pages. Carmabi compiled a series of pictures that show combinations of corals that are often mistaken for one another. Because terminology to describe each species is often subjective (i.e. has larger polyps or smaller ridges) having both species in one picture might help to get a better idea of how such closely related/ similar looking “species” can be distinguished from one another. Corals are now divided in four main groups (Montastraea, Agaricidae, Brain-looking corals and the Rest). All identifications are based on commonly used species names here on Curacao. This overview is a work in progress (and I welcome suggestions on how to shape this picture collection into a more user-friendly format), but I thought it would be useful to throw it out as it is.
The following links take you directly to each group:
