Ferdina mena, the false button star or red armpits sea star, is a species from the genus Ferdina.[1]
Characteristics
This species displays large rounded dorsal plates, white in the center and yellowing toward the tips of the arms, on a rust-colored background. It is particularly recognizable by the fact that the two plates located at each armpit are bright red[2].
Distribution
This species appears to be endemic to the western Indian Ocean, where it is found from South Africa to Madagascar, including the Comoros and Mozambique[2].
It is replaced in the Mascarene Islands by Ferdina flavescens (single-colored), and south of Durban by Ferdina sadhaensis (with white plates on a red background)[2].
Taxonomy
The species' description is the result of a re-evaluation of Ophidiasteridae that led to the discovery of new genera and species supported by a distinctive set of characteristics that support a new subfamily, the Ferdininae, a group originally outlined by Marsh and Price (1991) within the Goniasteridae.[1][3]
