Homoscleromorpha is a subclass of marine demosponges containing a single order, Homosclerophorida and a single family, Plakinidae. These sponges are massive or encrusting in form and have a very simple structure with very little variation in spicule form (all spicules tend to be very small). Reproduction is viviparous and the larva is an oval form known as an amphiblastula. This form is usual in calcareous sponges but is less common in demosponges.
