Metula (gastropod)
Metula is a genus of predatory sea snails, marine gastropod mollusks in the family Colubrariidae. These snails are found in tropical and subtropical waters around the world.
Description
Snails in the genus Metula typically have an elongated, fusiform shell. The shell is often sculptured with axial ribs and spiral cords, giving it a textured appearance. The aperture is usually relatively small and oval-shaped. The siphonal canal is short to moderate in length. Shell color varies among species and can include shades of brown, cream, and white.
Distribution
Species of Metula are found in various locations, including the Indo-Pacific region, the Atlantic Ocean, and the Mediterranean Sea. They generally inhabit sandy or muddy substrates in shallow to moderately deep water.
Ecology
Metula snails are carnivorous and actively hunt their prey. They are known to feed on polychaete worms and other small invertebrates. They use their proboscis to locate and capture their prey.
Species
Some recognized species within the genus Metula include:
- Metula angulata
- Metula cumingi
- Metula daphnelloides
- Metula elongata
- Metula fulgurans
- Metula hindsii
- Metula inflata
- Metula metcalfei
- Metula mitraeformis
- Metula obtusa
This is not an exhaustive list, and taxonomic classifications may change over time.
Taxonomy
The genus Metula was established by H. Adams and A. Adams in 1853. Its placement within the Colubrariidae reflects its morphological and ecological similarities to other members of this family. Ongoing research may lead to revisions in the taxonomy of this genus.
