This is an interesting article (linked below) about #biodiversity and #populationdynamics of #microscopic #seafloorfauna elements, and their presumed modes of #dispersal and ability to adapt to far away #ecologically different conditions. It focuses on the nematode genus #Halalaimus.
I want to point out that even terrestrial nematodes are masters of interesting #dispersalstrategies, evolved based on their small sizes and limited distance #mobility.

#Halalaimus is a microscopic #nematode genus commonly found in sediment on the seafloor. It lives 1–5 cm below the sediment surface and grazes on bacteria or organic materials in the sediment.

Identical micro-animals live in two isolated deep-sea environments. How is that possible?

It sounds almost impossible. And yet, the same nematodes live in two extremely isolated deep-sea trenches located 17,000 km apart.
