Live colossal squid captured on video in wild for first time ever

A young Mesonychoteuthis hamiltoni, the heaviest invertebrate on earth, was filmed in the Atlantic Ocean

The colossal squid, the heaviest invertebrate in the world, has been filmed alive in the wild for the first time since it was identified a century ago.

Growing up to 23ft (seven metres) long and weighing up to half a tonne, the squid, Mesonychoteuthis hamiltoni, is the heaviest invertebrate on the planet. The individual captured on film near the South Sandwich Islands, in the south Atlantic Ocean, is a baby, at just 11.8in (30cm) in length.
