Graceful Hunters of the Deep
Meet the Eels of Irukandji
Eels are some of the most fascinating and misunderstood animals in our lagoons. From sleek, curious swimmers to powerful hunters with incredible jaw strength, each species plays an important role in the underwater world. At Irukandji, you’ll get an up-close look at their behaviour, adaptations, and personalities as they glide through the water with serpentine grace. These remarkable creatures show just how diverse and surprising Australia’s marine life can be.
Undulate Moray (Gymnothorax undulatus)
The undulate moray is a striking eel species found in tropical Indo-Pacific reefs, easily recognized by its bold, wavy patterns. Listed as Least Concern on the IUCN Red List, this eel plays an important role as a reef predator, feeding on fish and crustaceans. Unlike freshwater eels, morays do not undertake long oceanic migrations; instead, they remain in coral reef habitats throughout their lives, hiding in crevices and ambushing prey. Their unique jaw structure allows them to grip and swallow prey whole, making them one of the ocean’s most efficient hunters.
Australian Long-finned Eel (Anguilla reinhardtii)
The Australian long-finned eel is a fascinating freshwater species found in rivers, lakes, and estuaries along eastern Australia. Listed as Least Concern on the IUCN Red List, these eels are remarkable for their extraordinary migration. After spending up to 20 years in freshwater, they embark on a journey of thousands of kilometers to spawn in the deep waters of the Coral Sea. Adults never return, but their larvae drift back on ocean currents to Australian rivers, continuing the cycle. This epic migration makes them one of nature’s most impressive travelers.
