coralliophilids

Coralliophilidae is a family of marine gastropod mollusks in the superfamily Muricoidea. They are commonly known as coralliophilid snails or coral shells and include numerous genera, with Coralliophila among the best known. The shells are usually sturdy and patterned, adapted to life on hard substrates in reef environments.

Habitat and distribution

Coralliophilids occur in tropical and subtropical seas around the world and are particularly associated with coral reefs. They are often found on live corals, coral rubble, or other hard substrates where they can blend with the reef surface.

Ecology and feeding

Many coralliophilids are specialized coral dwellers that feed on coral tissue, mucus, or encrusting organisms on the host. Their feeding can affect the growth and health of corals, especially in stressed or degraded reef systems. Feeding modes and host associations vary among species, but coral involvement remains a common trait.

Life cycle and reproduction

Reproductive strategies in coralliophilids vary, but most species produce eggs that develop either directly or as free-swimming free veligers in the larval stage. Larval dispersal, when present, can facilitate wide geographic distribution and colonization of new coral habitats.

Fossil record and significance

The Coralliophilidae have a fossil record that extends back to the Cretaceous, reflecting a long-standing association with reef ecosystems. Modern species continue to play a role in coral reef dynamics as predators or grazers, and their presence helps illuminate reef health and trophic relationships.
