Shane Gross, from Canada, captured the western toad tadpoles while snorkelling through lily pads in Cedar Lake on Vancouver Island, British Columbia.

He managed to snap a cloud of the amphibians, which are a near-threatened species due to habitat destruction and predators, while avoiding the visibility-reducing layers of silt and algae covering the bottom.

Titled The Swarm Of Life, the photograph has been crowned the winner of the Natural History Museum's prestigious Wildlife Photographer Of The Year 2024 competition out of a record-breaking 59,228 entries, from 117 countries and territories.

Kathy Moran, chair of the jury, said they were "captivated by the mix of light, energy and connectivity between the environment and the tadpoles".

This is the first time the species has been featured in the competition, which is now in its 60th year, she added.

Life Under Dead Wood

Alexis Tinker-Tsavalas, from Germany, was awarded the title of Young Wildlife Photographer of the Year, for an up-close image featuring slime mould on the right, and a macroscopic animal called a springtail on the left, taken in Berlin.

Tinker-Tsavalas used a technique called focus stacking, combining 36 images with different areas of focus together.

Judges said it showed great skill and "incredible attention to detail, patience and perseverance".

Here are some of the other category winners.

Free As A Bird - Alberto Roman Gomez, Spain (10 and under)

Alberto watched from the window of his father's car at the edge of the Sierra de Grazalema Natural Park, in Cadiz, Andalusia, to take this picture - managing to capture the stonechat bird as it was perched, between trips to gather insects.

An Evening Meal - Parham Pourahmad, USA (11-14)

Parham visited the Ed R Levin County Park in Milpitas, California, most weekends over a summer to take photographs showing the wildlife living in a busy city park. This picture shows a young Cooper's hawk eating a squirrel in the last rays of sunset.

Frontier of the Lynx - Igor Metelskiy, Russia

A lynx stretches in the early evening sunshine in the Lazovsky District in Primorsky Krai, Russia. The remote location and changing weather conditions meant access was tricky, and it took more than six months of waiting for Metelskiy to capture the image of the elusive animal.

On Watch - John E Marriott, Canada

This image also features a lynx, this one with its fully grown young sheltering from the wind behind it. Marriott had tracked the family group for almost a week through snowy forests in Yukon.

Practice Makes Perfect - Jack Zhi, USA

A young falcon practises its hunting skills on a butterfly above its sea-cliff nest. This was taken in an area in Los Angeles, California, visited by Zhi over the past eight years.

A Tranquil Moment - Hikkaduwa Liyanage Prasantha Vinod, Sri Lanka

This picture shows a young toque macaque sleeping in an adult's arms, taken after a morning of photographing birds and leopards at the Wilpattu National Park. Vinod spotted a troop of the macaques moving through trees above, and used a telephoto lens to frame this moment as a young monkey slept between feeds.

Wetland Wrestle - Karine Aigner, USA

Karine Aigner was leading a tour group when she noticed an odd shape in the water along the Transpantaneira Highway, in Mato Grosso, Brazil - binoculars confirmed she was looking at a flash of a yellow anaconda, coiling itself around the snout of a yacare caiman.

The Demolition Squad - Ingo Arndt, Germany

Arndt's image shows the dismemberment of a blue ground beetle by red wood ants - carving the dead animal into pieces tiny enough to fit through the entrance to their nest in Hessen, Germany.

The Artful Crow - Jiri Hrebicek, Czech Republic

This perching carrion crow, pictured in Basel, Switzerland, looks almost like an impressionist painting, judges said. To create the effect, Hrebicek moved his camera in different directions, while using a long shutter speed.

Under the Waterline - Matthew Smith, UK/Australia

Smith used a specially made extension he designed for the front of his underwater camera housing to create this split image of a leopard seal beneath the Antarctic ice in Paradise Harbour. The young seal made several close, curious passes, he said. "When it looked straight into the lens barrel, I knew I had something good."

Tiger in Town - Robin Darius Conz, Germany

A tiger sits on a hillside against the backdrop of a town where forests once grew in Nilgiris, Tamil Nadu, India. Conz was following the big cat as part of a documentary team filming the wildlife of the Western Ghats.

Dusting for New Evidence - Britta Jaschinski, Germany/UK

Jaschinski spent time at the Convention on the International Trade in Endangered Species (CITES) border force department, where confiscated animal products are tested. This image shows a crime scene investigator from London's Met Police dusting for prints on a confiscated tusk at Heathrow Airport.

Dolphins of the Forest - Thomas Peschak, Germany/South Africa

Peschak documents the relationship between endangered Amazon river dolphins, which are also known as botos or pink river dolphins, and the people with whom they share their home in the waters of both Brazil and Colombia.

The Wildlife Photographer Of The Year 2024 exhibition opens at the Natural History Museum, London, on Friday 11 October
