Caught in the net

The oceans are full of beautiful creatures. Unfortunately due to destructive tuna fishing practices around the world, many other marine animals including endangered species are being needlessly and indiscriminately caught and killed in the process.

  • Fish

    There are many sorts of fish in the sea, in the open ocean fish like jacks, Mahi Mahi and rainbow runners are found in tropical seas and often hang around with schools of tuna. Many tropical fish have stunning colours and patterns, with rainbow runners being named for their colourful stripes.

  • Bill fish

    The billfish are stunning ocean predators that are most recognised by their sword-like noses. They are strong, and fast, with the spectacular sailfish taking the record as the fastest fish in the ocean, managing swimming speeds of over 60mph.

  • Small whales

    Although they are often overlooked and poorly understood, there are lots of species of small whales in the world’s oceans, often travelling in social groups, communicating closely, and feeding together on small fish or squid. Pilot whales are a particularly sociable species, with large family groups which stick closely together and look after each other when sick or injured.

  • Dolphins

    Playful dolphins are the most recognisable small members of the whale family, they often seek out boats and humans at sea, which makes them seem very friendly. Dolphin pods can range from just a few animals, to many thousands in a group. They range from just over a metre long to 4 metres or more in length.

  • Sharks

    Sharks are awesome, they come in all shapes and sizes, and have lived in our oceans since the time of the dinosaurs. Hammerhead sharks have 360 degree vision, thresher sharks use their long tail to stun prey, and blue sharks can give birth to over 100 live babies which are known as ‘pups.’ Commercial fishing causes 100 million shark deaths every year

  • Whale Sharks

    Whale sharks are gentle giants, the biggest fish in the sea, with an adult being roughly the same length as a double decker bus. These slow-growing, gentle filter-feeders eat tiny plankton, and are harmless to humans.
