Common name: erect rope sponge

General information

The Compressed Sponge, Amphimedon compressa, is a species of sponge found in marine environments. It is known for its dense, compressed structure and is often a dark color, ranging from deep brown to black. This sponge is not as commonly kept in home aquariums as some other species, but it can be an interesting addition for those looking to diversify their tank's invertebrate population.

Care

Amphimedon compressa requires a tank with stable water conditions and strong water flow to mimic its natural environment. It is a filter feeder, relying on the water current to bring food particles to it. The sponge should not be exposed to air, as this can cause tissue damage. It is important to provide a diet rich in dissolved organic matter and plankton.

Reproduction

Sponges, including Amphimedon compressa, have a unique reproductive strategy that includes both asexual and sexual reproduction. They can reproduce asexually through budding or fragmentation, and sexually by releasing sperm into the water column to fertilize eggs in other sponges. The resulting larvae are free-swimming and will settle on a suitable substrate to grow into a new sponge.

Habitat

Amphimedon compressa is typically found in shallow waters of coral reefs, often in areas with strong currents. It attaches itself to hard substrates where it can effectively filter feed. This species is distributed in tropical and subtropical regions around the world.
