Summary

Chthamalus is a genus of barnacles known for their flat appearance and for being widely distributed across non-boreal coastal regions. Molecular studies have revealed cryptic species and complex taxonomic relationships.

Physical Characteristics

Small barnacles with distinct wall plate arrangements that differ from Balanidae species.

Identification Tips

In the field, reliable identification is limited to a few species; however, Chthamalid barnacles can be distinguished from Balanids by the overlapping arrangement of wall plates.

Habitat

Non-boreal coasts of the northern hemisphere and various regions in the southern hemisphere.

Distribution

Found along almost all non-boreal coasts globally.

Diet

Filter feeders, primarily feeding on plankton and organic debris suspended in the water.

Life Cycle

Barnacles have complex life cycles with larval stages that are planktonic before settling as adults.

Reproduction

Generally reproduce sexually, with external fertilization occurring in water.

Predators

Predators may include various fish species and invertebrates that feed on barnacles.

Ecosystem Role

Chthamalus barnacles play a role in marine ecosystems by providing habitat and food for other organisms.

Evolution

The genus is noted for being paraphyletic, with some species previously classified under Microeuraphia now nested within Chthamalus.
