Join us as we explore Shark Point, one of Thailand's best dive spots. We're treated to the rare sight of a reef squid (notoriously difficult to capture on film!), a feeding porcupine pufferfish fighting off scavenging wrasses hellbent on stealing its meal and a majestic lionfish hidden in a barrel coral.

You might think deep below the waves is the place to look for the most interesting marine species, but on this dive in Palong, Thailand our crew uncovers an abundance of ocean creatures, from rabbitfish to sergeant majors (and even a hitchhiking remora!), just metres below the surface.

With coral reefs in trouble pretty much the world over, this episode of Wild Oceans is a rare treat indeed.

It’s a reef in progress! Off the Thailand coast, underwater pyramids of concrete blocks are forming the beginnings of an amazing artificial reef … and nearby in the shallows is a nursery for fledgling corals. This reef-in-the-making is already attracting plenty of marine life (keep an eye out for a pufferfish getting some dental work done courtesy of a busy cleaner wrasse).
