Today marks the announcement of 2019's Underwater Photographer of the Year, so we'd like to share our favourite pictures with you from this years entries, specifically those from the 'Marine Conservation Photographer' category.

Underwater Photographer of the year 2019: Richard Barnden with 'The Gauntlet'

This image tells the story of a passing by Parrotfish who was looking for somewhere to hide. Unfortunately, as swarms of sharks followed close by, one grey reef shark suddenly grabbed it's prey by the head as another twisted underneath it to get a better grip. These are only a handful of the estimated 700 sharks that are patrol the mouth of the Fakarava South Pass channel by day and, as shown here, hunt at night.

Marine Conservation photographer of the year 2019: Eduardo Acevedo with 'Caretta caretta turtle'

The Caretta caretta turtles often visit the Canary Islands after their long trip across the Atlantic ocean, always working to avoid dangers such as plastic and fishing equipment. Here, this turtle was unfortunate enough to get tangled in a net. Luckily freedom was restored as two underwater photographers nearby helped save her.
