During week two of the International Union for Conservation of Nature expedition to research mysterious seamounts in the southern Indian Ocean, scientists catch this Phyllosoma lobster larva at a depth of 750m.
At 50m closer to the ocean surface, at a depth of 700m, the scientists discovered this Phronima species. Resembling a shrimp, it is actually a small, translucent amphipod.
Also at 700m lurked this barrel eye fish, which goes by the scientific name Opisthproctus grimaldii.
A heteropod was found at 300m. Despite appearing not to, the creature has a shell, as it is a type of ocean-going predatory mollusc.
At 700m, the expedition nets caught a viperfish, which belongs to the genus Chauliodus. A fierce predator, it grows up to 60 cm long and has long needle-like teeth and hinged jaws.
At the same depth lives another fish species, Stemonosudis.
The expedition scientists are throwing whale bones overboard in a bid to encourage bone-eating worms, such as this snotflower worm, to colonise them. Little is known about such worms in the Indian Ocean.
More common are crustacean larvae, such as this individual caught at a depth of 350m.
Above the ocean waves, ocean-going birds catch the eye.
Wandering albatrosses have been following the expedition research vessel Dr Fridtjof Nansen, perhaps hoping to feed on scraps of food leftover by the crew, or from nets used to trawl for specimens.
Also making an appearance, and belying its name, was this Shy albatross.
White-chinned petrels have also been common visitors to the boat. Visit Earth News to keep up with the ship and its crew as they survey the ocean.
