Nephtheidae
Nephtheidae is a family of soft corals belonging to the order Alcyonacea. They are commonly known as “sea whips” or “sea fans” due to their distinctive branching forms. Nephtheidae are characterized by their flexible, leathery skeletons composed of scattered spicules, which are small, needle-like structures that provide support and protection. These corals are often brightly colored and can grow to considerable sizes, with some species reaching several meters in height.
Common Names
Nephtheidae are commonly referred to as "sea whips" or "sea fans," but other names may be used depending on the specific species or region. Some examples include:
- Sea Pens
- Gorgonians
- Octocorals
Characteristics
Nephtheidae exhibit several key characteristics that distinguish them from other coral families:
- Branching Form: They typically grow in branching patterns, resembling whips, fans, or trees.
- Flexible Skeleton: Their skeletons are composed of scattered spicules embedded in a protein matrix, giving them a flexible, leathery texture.
- Polyp Structure: They possess polyps, the individual feeding units of the coral, which are typically retracted during the day and extended at night for feeding.
- Bright Coloration: Many Nephtheidae species are brightly colored, often displaying hues of red, orange, yellow, or purple.
Environments
Nephtheidae are found in a variety of marine environments, primarily in tropical and subtropical waters. They are commonly observed on coral reefs, rocky shores, and seagrass beds. Some species may also inhabit deeper waters, while others are found in shallower, intertidal zones.
