Axinyssa ambrosia

(de Laubenfels, 1936)

Orange-Red Knot Sponge

Range: Western Atlantic Ocean: Caribbean to Colombia.

Natural Environment: Inhabits shallow coastal waters where it encrusts dead corals, coral rubble and other available hard substrates.

Aquarium Suitability: May arrive attached to lower sides of live rock/rubble. Removed when seen.

Keep in mind, if a hitchhiker sponge arrives attached to a coral specimen or live rock, it is reasonable to assume that at one time it was subjected to 'air' when the specimen or rock was harvested/shipped and/or transferred to various storage areas, thereby endangering the ongoing lifespan of the hitchhiker sponge, as it should never to subjected to air! Therefore the ongoing culture of hitchhiker sponges is dismal at best!

Best left in the wild.
