A deep dive: Weird and wonderful new creatures and features of the deep sea - Hindustan Times

Sheer delight: While out surveying the remote Phoenix Islands Archipelago, Schmidt Ocean Institute scientists captured rare footage of a “glass octopus”, named so because it is completely see-through.

This fresh sighting was made by marine biologist Alan Jamieson, using an underwater camera trap that settles on the seabed and photographs life as it swims and shuffles by.

An international group of scientists went on a month-long deep-sea research voyage to explore marine life in the abyss off eastern Australia.

A quick look at the history books revealed that Typhlonus nasus is one of the earliest-known deep-sea species, first discovered by the HMS Challenger, which undertook a landmark oceanographic survey in the 1870s.

Holy smoke: At the bottom of the Arctic Ocean, beneath the permanent sea ice near the North Pole, are hydrothermal vents letting out a super-heated soup from deep underground.

The Aurora vent field, first detected about two decades ago, lies at the depth of 4,000 metres and was explored in detail by the HACON expedition in September-October 2021.
