Amphipholis

Amphipholis is a large genus of brittle stars (Ophiuroidea) found in oceans worldwide from tropics to Arctic and Antarctic regions. Some species have been used to study echinoderm development (Amphipholis kochii ) and bioluminescence (the dwarf brittle star, Amphipholis squamata ).

Systematics
Amphipholis is a large genus with potentially many cryptic species. The high variability may be due to common parthenogenetic reproduction. The type species of the genus is Amphipholis januarii  Ljungman, 1866 (=Amphipholis gracillima ( Stimpson, 1852 )).
