Sea Lion-Assisted Research Sheds Light on Mysterious Ocean Floor Habitats Off Australia’s Coast

Around the world, an aquatic enigma continues to baffle researchers. As Nathan Angelakis, a Ph.D. student at the South Australian Research and Development Institute (Aquatic Sciences) and the University of Adelaide, remarked, "For most of the ocean, we don’t know what the bottom looks like." In response to this challenge, a recently launched research initiative enlisted the help of unique underwater "assistants" - four trained sea lions named Daphne, Phoebe, Iris, and Pasithea.

Exploring the Unseen Depths

The daring animals, equipped with underwater video cameras, dived into unexplored parts of the ocean floor along Australia’s southern coast. Their efforts yielded groundbreaking footage revealing previously unseen underwater landscapes, including meadows of leafy seaweeds, craggy rocks adorned with corals, and, for the first time, a mother Australian sea lion teaching her pup the art of hunting.

Published Findings

The discoveries made during these oceanic explorations were published in the journal Frontiers in Marine Science on Wednesday. The team, led by Angelakis, aims for this pioneering research to enhance scientists' understanding of the various habitats utilized by sea lions, as well as to inform strategies for safeguarding these ecosystems from further degradation, particularly in light of the endangered status of these marine mammals.

Angelakis and his colleagues are hopeful that by decoding the nature of these diverse habitats frequented by the Australian sea lions, they can pave the way for improved conservation measures and practices to protect these important ecological areas.
