Common name: Leopard Sea Cucumber

Scientific name: Bohadschia argus Jaeger, 1833
A large sea cucumber, Bohadschia argus, is found on the sand and rubble seafloor in Palau. This echinoderm can eject sticky, toxic tubules out of its anus that deter predators.

General information

The Leopard Sea Cucumber, scientifically known as Bohadschia argus, is a striking and sizable invertebrate commonly found in the tropical Indo-Pacific region. It is known for its distinctive dark body covered with bright, eye-like spots that resemble a leopard's coat, which is where it gets its common name. These spots are not just for show; they serve as a form of camouflage, breaking up the animal's outline and making it less visible to predators.

Care

Bohadschia argus requires a spacious aquarium with a deep sand bed to accommodate its burrowing behavior. It is a detritivore, feeding on organic matter and microorganisms within the sand, which helps to naturally clean and aerate the substrate. Stable water conditions and a diet supplemented with meaty foods are essential for its well-being.

Reproduction

Reproduction in sea cucumbers, including Bohadschia argus, typically involves spawning, where eggs and sperm are released into the water column. In the aquarium, spawning is rare, but if conditions are ideal, it may occur. The larvae that hatch are planktonic before settling to the bottom and developing into juveniles.

Symbiosis

While not known for hosting other organisms like some of its relatives, the Leopard Sea Cucumber can contribute to a symbiotic relationship within the aquarium by providing a natural cleaning service, consuming detritus and helping maintain a balanced ecosystem.

Habitat

The natural habitat of Bohadschia argus spans across the warm waters of the Indo-Pacific, from the Red Sea to the islands of the Pacific Ocean. It is typically found on reef flats and lagoons, often partially buried in sandy or muddy substrates.
