Bohadschia koellikeri

Bohadschia koellikeri is a species of sea cucumber belonging to the family Holothuriidae. It is commonly found in the Indo-Pacific region, inhabiting a variety of marine environments, making it a prevalent presence in these aquatic ecosystems.

Description & Characteristics

Bohadschia koellikeri is a relatively large sea cucumber, reaching a maximum size of about 30 cm in length. Its body is typically cylindrical and elongated, with a smooth, leathery skin. The color of Bohadschia koellikeri can vary depending on its habitat, ranging from shades of brown and grey to black. It has a distinct mouth at one end and an anus at the other, surrounded by numerous tentacles. These tentacles are used for feeding and are typically short and stubby.

Habitat and Occurrence

Bohadschia koellikeri is a common species in the Indo-Pacific region, found in a variety of marine environments, including coral reefs, rocky shores, and seagrass beds. It is typically found in shallow waters, with a depth range of 0 to 30 meters. The species is particularly prevalent in the tropical and subtropical regions of the Indian Ocean and the Pacific Ocean. It is a common inhabitant of the intertidal zone, but can also be found in deeper waters, as well.

Taxonomy

Bohadschia koellikeri is classified as belonging to the Class: Holothuroidea, Order: Holothuriida, and Family: Holothuriidae. This family is known for its diversity, containing a wide array of sea cucumber species with varying shapes, sizes, and adaptations. The order Holothuriida encompasses a vast majority of sea cucumbers, characterized by their elongated bodies and feeding mechanisms that involve depositing sediment through their mouths. The Class Holothuroidea, encompassing all sea cucumbers, plays a crucial role in marine ecosystems as deposit feeders and recyclers of organic matter.

Feeding

Bohadschia koellikeri is a deposit feeder, meaning it obtains its food from the sediments it ingests. It uses its numerous tentacles to collect organic matter, including detritus, algae, and small invertebrates, from the surrounding environment. The tentacles are then retracted into the mouth, where the food is passed through the digestive system. This feeding strategy contributes to the overall health of marine ecosystems by helping to break down organic matter and recycle nutrients.
