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[1]) and bioluminescence (the Dwarf brittle star, Amphipholis squamata[2][3]).

Systematics

Amphipholis is a large genus with potentially many cryptic species.[4] 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)).

Species include:[5]

  • Amphipholis abdita
  • Amphipholis andreae
  • Amphipholis bananensis
  • Amphipholis clypeata
  • Amphipholis elevata
  • Amphipholis erecta
  • Amphipholis geminata
  • Amphipholis goesi
  • Amphipholis gracillima
  • Amphipholis granulata
  • Amphipholis kochii
  • Amphipholis laevidisca
  • Amphipholis limbata
  • Amphipholis linopneusti
  • Amphipholis litoralis
  • Amphipholis loripes
  • Amphipholis microdiscus
  • Amphipholis misera
  • Amphipholis murmanica
  • Amphipholis nudipora
  • Amphipholis pentacantha
  • Amphipholis platydisca
  • Amphipholis procidens
  • Amphipholis pugetana
  • Amphipholis puntarenae
  • Amphipholis sigillata
  • Amphipholis similis
  • Amphipholis sobrina

gollark: I run out of memory quite often because I underprovisioned RAM.
gollark: My current solution is just to use a userspace OOM killer.
gollark: But then it would run out of RAM.
gollark: I do. It just freezes horribly.
gollark: I've never actually seen the in-kernel OOM killer do anything.
