Red sponge

Yellow tube sponge

Yellow tube sponge

Sponge biodiversity and morphotypes at the lip the wall site in 60 feet of water . Included are the yellow tube sponge, Aplysina fistularis, the purple vase sponge, Niphates digitalis, the red encrusting sponge, Spiratrella coccinea, and the gray rope sponge, Callyspongia sp.

Xestospongia muta, the barrel sponge, may live for 100 years and grow to over 6 feet tall. While populations have declined at sites throughout the Caribbean, they appear to be quite healthy on Little Cayman Island.

Some sponges, like this vase sponge (Callyspongia plicifera), do not host a microbial community that is substantially different from that found in the surrounding water column. Other sponges contain microorganisms that are not commonly found in the water and they are considered bacteriosponges.

This brown sponge (Agelas conifera) is common on both shallow and deep Caribbean reefs, but grows to enormous proportions on deeper reefs where it can orm long creeping arms extending into the depths.

The liver sponge, Plakortis sp., produces a series of important chemical compounds that deter predators and have biomedical antimicrobial activity.

Agelas conifera is a common sponge of the Caribbean over a broad depth gradient. This makes it a great model organism to study phenotypic plasticity.
