Spheciospongia papillosa

View scientific description and taxonomy

Scientific Details

These sponges are massive in growth form with specialised incurrent pore sieve plates. In this species, the loss of red light at depth makes it appear a deep royal blue in colour, their purple colour only visible with camera lights or in sunlight.

Brief species characters:
Growth form: irregular.
Mineral skeleton: siliceous.
Megescleres: monaxone.
Surface texture: papillose, sieve-plates.

Family level characters:
Sponges in this family possess the pin-head megascleres or tylostyles and a variety of microscleres as shown.

Order level characters:
Hadromerid sponges are often brightly coloured and are also characterised by a radial arrangement of megascleres in the cortex. The megascleres are pin-head shaped tylostyles and pointed, rod-shaped oxeas. Microscleres if present may be star-shaped, rod-shaped or spiral and are key characters when separating these sponges at the family level.
