Two mottled moray eels against a dark background with a cloud of white sperm between them. One of the eels has a closed mouth and the other an open mouth, showing sharp teeth.

Tony Wu (USA/Japan) provides a first-time glimpse into the mating ritual of Abbott’s moray eels.

Tony has been working with biologists to address a knowledge gap in the social behaviour of this eel species. Guided only by a dim red-light source to minimise disturbance, and using a customised fisheye camera lens, he has studied this male since 2024 as it visits females that dwell in crevices on the reef.

This is likely the first time Abbott’s moray eel courtship and spawning have been documented, and the observations from Tony’s work with biologists are feeding into published scientific studies.

Tony has been documenting marine life since 1995. First were the tropical reefs of Southeast Asia, followed by long-term projects centred upon large cetaceans and spawning aggregations. He’s now devoted to the oceans of Japan, which encompass everything from tropical to Arctic environments, as well as many unique habitats in between. Tony views himself as a translator, interpreting and communicating on behalf of the underwater world by using photographs, scientific information and writing.
