Chasing Glowworms

We donned our striped thermals, rubber boots, and helmets and tramped down a muddy hillside to the entrance to Mangarongapu Cave. If we wanted to see glowworms in their natural environment, we were going to have to work for it. Most bioluminescent organisms live in the sea, particularly in the deep. On land, bioluminescent species include glowworms, a catch-all term that refers to luminescent insects like fireflies (winged beetles) and the fungus gnat of New Zealand, among others.

A Colossal Deep-Sea Find

Ten years ago, the crew of the San Aspiring fishing vessel, which was on the hunt for Antarctic toothfish, pulled in a longline and discovered they had caught something unexpected. It was a huge, red blob—a deep-sea-dwelling colossal squid (Mesonychoteuthis hamiltoni) that had also been hunting for toothfish more than a mile below the surface. Recognizing they had something unique on their hands, the crew hauled the now-deceased squid onboard and froze its body.
