Leptosynapta dolabrifera is a species of sea cucumber belonging to the family Synaptidae. These invertebrates play a crucial role in marine ecosystems, contributing to nutrient cycling and sediment turnover.
Description & Characteristics
Leptosynapta dolabrifera is a relatively small sea cucumber, with individuals typically reaching a maximum size of about 10 cm. The body is elongated and cylindrical, with a smooth, leathery texture. The color can vary depending on the environment, ranging from pale brown to reddish-brown. Like other sea cucumbers, Leptosynapta dolabrifera possesses a unique feeding apparatus known as a buccal tube, which is used to gather food from the surrounding sediment.
Habitat and Occurrence
Leptosynapta dolabrifera is commonly found in the intertidal zone and subtidal regions of coastal waters. Its preferred habitat includes sandy, muddy, or gravelly sediments. This species is particularly abundant in shallow coastal areas, often inhabiting the infralittoral zone, where it thrives in environments influenced by both terrestrial and marine influences.
Taxonomy
Leptosynapta dolabrifera is a member of the Class Holothuroidea, the class of sea cucumbers. This species belongs to the Order Apodida, which encompasses sea cucumbers characterized by their lack of appendages. Within this order, Leptosynapta dolabrifera is classified within the Family Synaptidae, a group known for their thin, elongated bodies and their ability to burrow in soft sediments.
Feeding
Leptosynapta dolabrifera is a deposit feeder, meaning it obtains its nutrition by consuming organic matter from the sediments. Its feeding apparatus, the buccal tube, enables it to ingest large quantities of sediment, extracting nutrients from the detritus and microorganisms within. This feeding strategy contributes to the breakdown and recycling of organic matter in marine ecosystems.
