Who are we?

Ocean Giants Trust is an international conservation charity, which protects the ocean’s largest and most threatened marine species, and their biologically important habitats.

What do we do?

Responding to the global threat of extinction to some of the most iconic species on the planet, we believe that only through integrating international research, with local marine conservation and education will Ocean Giants survive and thrive.

Who do we work with?

Working exclusively with both internationally renowned scientists, and local project partners we offer a new, refreshing and more effective approach to the understanding and protection of Ocean Giants.

Otherwise known as the ocean sunfish, they can weigh up to 1000 kg!

They can lay up to 300,000,000 eggs at ONE time. 
They are clumsy swimmers, waggling their large dorsal and anal fins to move and steering with their clavus. 
Their food of choice is jellyfish, though they will eat small fish and huge amounts of zooplankton and algae as well. 
They are harmless to people, but can be very curious and will often approach divers. .

  • Repost: one of our favourite photographers  @alexkyddphoto • Leopard shark (aka zebra shark) in the shallows of Coral Bay, Ningaloo Reef. ••• DYK - young zebra sharks have a completely different patterns to their older counterparts? 
Though solitary for most of the year, they form large seasonal aggregations. 
They are  nocturnal and spend most of the day resting motionless on the sea floor. 
At night, they actively hunt for molluscs, crustaceans, small bony fishes, and possibly sea snakes inside holes and crevices in the reef.

They are an endangered species. 
And back in 2017, a female zebra shark in an Australian aquarium  produced live offspring asexually, three years after being separated from her long-term mate. .
