Unveiling the Ocean’s Hidden Wonders: Discoveries of a Batfish and a Blind Eel

Exploring the Depths: Remarkable New Species Unveiled in the Deep Sea


A groundbreaking research voyage in Australia’s remote Cocos (Keeling) Islands Marine Park has led to the rare discovery of several deep-sea creatures, including a batfish and a blind eel. These findings, made by a team of researchers in collaboration with Bush Blitz, Parks Australia, Australian Museum Research Institute, and the Western Australian Museum, offer a glimpse into the mysterious world beneath the ocean’s surface.

The research vessel, operated by CSIRO, Australia’s national science agency, meticulously mapped the park area, collecting samples from depths of up to three miles below the surface. The 35-day journey, covering nearly 7,000 miles, revealed a diverse array of marine life, including a blind eel with transparent, gelatinous skin and a deep-sea batfish equipped with a tiny “fishing lure” on its snout to attract prey.

Among the other fascinating species discovered were the Highfin Lizard fish, known for their deep-sea predatory nature and mouths full of long sharp teeth, and Sloane’s Viperfish, characterized by their huge fang-like teeth and rows of light organs along their underside. These discoveries not only highlight the rich biodiversity of the ocean but also underscore the importance of exploring and understanding these remote ecosystems.

Jason Mundy of Parks Australia emphasized the significance of the voyage in better comprehending the unique habitats and species of these remote waters. The expedition’s success in uncovering these hidden marine treasures demonstrates the vast, unexplored potential of the ocean’s depths and the need for continued research and conservation efforts in these enigmatic regions.
