Alepas
Alepas is a genus of goose barnacles in the family Alepadidae. These barnacles are distinguished by their elongated, worm-like stalks and small, conical shells. Unlike many other barnacles, Alepas species are typically found attached to the bodies of marine animals, such as whales, sea turtles, and fish, rather than hard surfaces. Their distribution is cosmopolitan, with species found in various oceanic regions.
Common Names
Common names for Alepas species include "whale barnacles" and "turtle barnacles," reflecting their frequent association with these hosts.
Characteristics
Alepas species share several defining characteristics:
- Elongated stalk: The most noticeable feature of Alepas barnacles is their long, flexible stalk, which can extend significantly beyond the shell.
- Conical shell: The shell, or carapace, is small and conical, typically consisting of six plates. This shell houses the animal's body and reproductive organs.
- Cirri: Like other barnacles, Alepas have six pairs of feathery appendages called cirri, which they use to filter food particles from the water.
- Sessile lifestyle: Once attached to a host, Alepas barnacles remain in place, feeding and reproducing.
Environment
Alepas species are found in a variety of marine environments, typically associated with their hosts. Their distribution is global, with species occurring in both warm and cold waters.
