Plakortis is a genus of marine sponges in the order Homosclerophorida,[1] first described by Franz Eilhard Schulze in 1880.[1][2]

Description

Plakortis sponges are characterised by having:[3]

  1. inorganic (spicular) skeletal complement
  2. Skeleton composed mainly of diods, triods, and/or calthrops in one size class
  3. Lophose diods, triods, or calthrops complement the main skeleton of non-lophose spicules
  4. no lophose spicules
  5. diactinal "microscleres" (microrhabs) in some species
