modern plesiosaur

Populations of plesiosaurs have been declining world wide, all but a handful of large species now still roam the open oceans while smaller plesiosaurs fare even worse from poaching and pollution, those living along coasts and mangroves have pretty much vanished.

A small deep sea dwelling plesiosaur had recently been discovered, a peculiar one which has adapted to filter feeding In the frigid ocean depths of Greenland and Iceland. However, this animal too is already at the brink of extinction, as the very few that were discovered were those tangled in fishing nets and choked to death after ingesting microplastics carried over from ocean currents all over the globe.
