Spotted Garden Eel

Heteroconger hassi

Habitat & Distribution :  Indo-Pacific Ocean

Diet : Zooplankton

Size: 40 cm

Lifespan : 35 years

Deskripion

This species has a white body densely covered in small black spots and three distinct larger black patches. Known for living in sandy, coral reef burrows, they have large yellow eyes, an upturned mouth, and a circular cross-section body

Behavior

These small shy fish live in large, sedentary colonies of up to thousands in sandy sea beds. They anchor in individual vertical burrows, reinforcing them with mucus, and leave their tails inside while extending their heads into the current to feed on zooplankton. They sway together, resemble seagrass, and retract into the sand at the slightest sign of danger

Reproduction

Spotted garden eels reproduce by forming pairs within a colony, where males and females bring their burrows closer together during breeding season. They are pelagic spawners, meaning they entwine their upper bodies to fertilize eggs, which are then released into the current to float as plankton

Communication & Perception

They communicate primarily through specialized body positioning and movement within their large colonies to indicate safety levels, warn of danger, or display courtship.

Predators

Snake eels, triggerfish, stingrays, hogfish
