Dendropoma
Dendropoma is a genus of small, colonial marine snails in the family Vermetidae, commonly known as worm snails or “tree snails.” These snails are characterized by their tube-shaped shells that are often found growing in clusters, resembling branches of a tree.
Common Names
Dendropoma species are commonly referred to as "tree snails" due to their branching, tree-like growth habit. Some species are also known by more specific names, such as the "Mediterranean tree snail" (Dendropoma petraeum).
Characteristics
Dendropoma snails are characterized by their:
- Tube-shaped shells: These shells are often white or cream-colored and can grow up to several centimeters in length.
- Colonial growth habit: Dendropoma snails live in colonies, with individual snails attaching their shells to one another to form branching structures.
- Sessile lifestyle: Once attached to a substrate, Dendropoma snails are generally immobile.
- Filter feeding: Dendropoma snails feed by filtering microscopic organisms from the water.
Environment
Dendropoma snails are found in a variety of marine environments, including:
- Rocky shores: They are often found attached to rocks in the intertidal zone.
- Coral reefs: Dendropoma snails can also be found in shallow, warm waters of coral reefs.
- Seagrass meadows: Some species inhabit seagrass meadows, where they attach themselves to seagrass blades.
