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.

Ostracoderms, jawless fishes of Silurian and Devonian times. Shown in one sketch as they might have appeared while searching for food on the floor of a Devonian sea. All were probably suspension-feeders, but employed a strong pharyngeal pump to circulate water rather than the much more limited mode of ciliary feeding used by their protovertebrate ancestors and by amphioxus today. Modern lampreys are believed to be derived from the anaspid group.

EDIT: Did I mention they have armor? ‘Cause they were totally armored fish. HOW COOL.
