General information

The Iophon Sponge, Iophon laevistylus, is a lesser-known but fascinating species in the marine aquarium hobby. This sponge belongs to the phylum Porifera, which is characterized by their porous bodies and a simple level of organization. Sponges like Iophon laevistylus are filter feeders, drawing water through their bodies to extract nutrients.

Care

Caring for Iophon laevistylus requires a well-established aquarium with stable water conditions. They thrive in moderate to low light environments and require a strong water flow to deliver the planktonic food they filter from the water. It's crucial to maintain high water quality, as sponges are sensitive to elevated levels of nitrates and other pollutants.

Reproduction

Sponges have a unique reproductive strategy that includes both sexual and asexual reproduction. Iophon laevistylus can reproduce by releasing gametes into the water column or by budding, where a part of the sponge breaks off and grows into a new individual.

Habitat

Iophon laevistylus is typically found in colder waters and can be located on rocky substrates or attached to other hard surfaces. In the wild, they are often found at various depths, sometimes in areas with strong currents which aid in their filter-feeding lifestyle.
