Heavy-metal marine biologist, Tom the Blowfish Hird, comes face to face with sea creatures and conducts experiments to reveal the secrets and mysteries of the oceans.

Tom Hird dives with seals to investigate their super-sensitive whiskers, tests his shooting skills against an archerfish and fires a cannon to show the power of a mantis shrimp's punch.

Tom Hird dives with manta rays, jumps on a skateboard to show how remoras hitch a ride, discovers why boxer crabs use anemones for gloves and how herrings communicate by farting.
