We meet Goldfish in his tank, where he shows us where he came from and he explains their three month memory and unique ability to see in colour. Goldfish explains they are social animals who love much bigger spaces.

Jellyfish shows us how they catch their prey and fend off predators using their stinging tentacles and can see their food after they eat it because of their see-through bodies.

We meet the Angler Fish who lives in the deepest, darkest parts of the ocean. She shows us how they’re the only ones who catch food using a bright Lure which hangs from the top of their spine.

Giant Clam explains what they eat that help them to grow from being very tiny clams to giant ones. They also have a very effective defense mechanism that has helped them to live for up to 100 years

We meet the shy Boxfish hiding in the reefs near Australia. She explains their unconventional shapes, sizes and what they like to eat. Despite her peaceful nature, she still has all sorts of creatures after her - so it's a good thing she's got her poison to protect her.
