Leptosynapta
Leptosynapta is a genus of sea cucumbers belonging to the family Synaptidae. These marine invertebrates are commonly known as “burrowing sea cucumbers” due to their lifestyle. They are found in various marine environments worldwide, inhabiting soft sediments and often burying themselves within the substrate.
Characteristics
Leptosynapta species are characterized by their elongated, cylindrical body, often with a pointed anterior end. They lack the calcareous ossicles, which are common in other sea cucumber groups. The body wall is typically thin and flexible, allowing them to burrow efficiently.
Environments
Leptosynapta species are found in a wide range of marine environments, including intertidal zones, subtidal areas, and deep sea habitats. They typically inhabit soft sediments, such as sand, mud, and silt.
Common Names
While "burrowing sea cucumbers" is a common name, specific species may have other common names depending on their location. For example, Leptosynapta clarki, found in the Pacific Northwest, is sometimes called the "Clark's burrowing sea cucumber."
