The Unstartled Steppes of Dream
Inquiries, Requests, and a Place to Spill Your Guts   Submissions  
I am Ashley.
This is my personal blog. If you want just marine biology, go here.
I love the world; I really don't like people.
I balance all this animosity towards the human race with being an almost always kind and gentle being to all creatures.
I'm highly introverted and nature is my primary escape from people.
Creepy-crawly-slimy things are my favorites. Dinosaurs are fantastic.
Future marine biologist; presently an amateur entomologist, ichthyologist, artist, biologist, and writer.
Literature, video game, and music connoisseur.
I'm so full of passion for the world that it hurts.
I think a lot, I laugh a lot, I love a lot.
Almost none of the photos are mine and only some of the drawings are mine.
Listen in.

The earth’s greatest mass migration, (apparently) referred to as the diel vertical migration and also known as the diurnal vertical migration, takes place every single day in the ocean. In temperate and tropical regions, zooplankton migrates to the ocean surface at night and then moves down again during the hours of daylight. In a single day, this vertical movement may range from 400 to 1,000 meters, depending on the size and type of animal involved. In polar regions, where darkness lasts for several months, zooplankton migrates up and down on a seasonal basis, being at the surface during summer and at depth in winter.It is thought that zooplankton rises to feed on the phytoplankton that lives in the surface waters, but then retreats to depth for safety, or possibly because it expends less energy in cooler water.
