Animals Are Rising From The Deep.

if these two articles are anything to go by,

Norway's Beitstadfjord has been so severely invaded by monster deep sea jellyfish that, just two years since their arrival, they have driven out all of the local fish, the innermost arm of the Trondheimsfjord now holds an estimated 40,000 tonnes of the helmet jellyfish, only a few years after the fiery red peril first appeared in its waters,

according to Norway's VG newspaper, Jarle Mork, a researcher at NTNU in Trondheim, caught vast quantities of the slimy animal in a single trawl, 'we took up 3.5 tons of monster jellyfish in under ten minutes', he said. 'there was a tremendous amount more than we expected, the trawler winch was just about to give way', Periphylla periphylla usually lives at depths of 1,000 meters but has in recent decades began invading the shallow waters of the fjords, 'the helmet jellyfish is a real beast which has now established itself as the top predator in the inner Trondheimsfjord', he said, scientists have prepared a paper for further reading although it appears reading the paper this phenomena is not unique to just Trondheimsfjord, meanwhile on the other side of the world,

sea slugs collectively known as nudibranchs are rising from the deep, spiky sea slugs, known as Hopkins' rose nudibranch, named after Timothy Hopkins, are invading northern California's coast in large numbers, and scientists believe changes in the ocean's temperatures are to blame, the vibrant, pink sea slugs are common in tide pools near Los Angeles and San Diego, but now large numbers of the inch-long rose nudibranch are being found as far north as Humboldt County, California, researchers from the University of California, Santa Cruz say that warmer ocean temperatures are driving the sea slugs north in search of more comfortable waters, a news release from the university explained that nudibranchs haven’t been this densely populated, at dozens per square meter, since 1998, 'we haven’t seen anything like it in years, these nudibranchs are mainly southern species, and they have been all but absent for more than a decade', said John Pearse, professor emeritus of ecology and evolutionary biology at UC Santa Cruz, the Hopkins' rose nudibranch sea slug has appeared in Santa Cruz, San Francisco, and Bodega Bay over the past couple of weeks, wait a second, Bodega Bay, I have heard of this place before, I know, The Birds! now this is getting scary.
