Corymorphidae

Common Names

Corymorphidae are not commonly known by any specific names. However, the individual species within the genus Corymorpha may be referred to by their scientific names.

Characteristics

Corymorphidae are characterized by the following features:

• Solitary polyp stage: Unlike many other hydrozoans, Corymorphidae do not have a distinct medusa stage in their life cycle. They exist as solitary polyps throughout their lives.
• Hydranth: The polyp has a single, prominent hydranth, which is the feeding structure containing tentacles.
• Cnidocytes: Like all cnidarians, Corymorphidae possess stinging cells called cnidocytes on their tentacles, which are used for capturing prey.
• Peduncle: The polyp is attached to the substrate by a stalk known as a peduncle.
• Lack of perisarc: Corymorphidae lack a perisarc, which is a protective chitinous covering present in many other hydrozoans.

Environments

Corymorphidae are typically found in intertidal and subtidal regions of coastal waters. They prefer environments with moderate water flow and ample food sources, such as zooplankton. The polyps attach themselves to various substrates, including rocks, seaweeds, and other invertebrates.
