With their double rows of bioluminescent organs with purple lights, Mueller’s pearlsides are very special fish to see. They have these lights because they live in very deep water. In March Joost van der Hoek of the Dutch Institute for Sea Research discovered a Mueller’s pearlside on the beach of Texel. It seems to be an extraordinary discovery because in the past 10 years but one other fish was found on Dutch beaches. That was in 2008 on the beach of Ouddorp.

From the BBC:

A new record has been set for the world’s deepest fish.

The bizarre-looking creature, which is new to science, was filmed 8,145m beneath the waves, beating the previous depth record by nearly 500m.

Several other new species of fish were also caught on camera, as well as huge crustaceans called supergiants.

The animals were discovered during an international expedition to the Mariana Trench, which lies almost 11km down in the Pacific Ocean.

Pollution may trigger disease and intersex traits in deep-water fish, researchers say: here.
