The helmet jelly (Periphylla periphylla) is one of the most common deep sea jellyfish in the world and is found in every ocean except for the Arctic. Living between 1000 and 7000 meters depth, it moves up to shallower waters at night because light is toxic to the species. To avoid predation, the helmet jelly can use bioluminescence as a means of distracting predators.

I am Ashley, an incredibly introverted environmental enthusiast.
I'm studying to be a marine biologist.
I have a fierce love for all living things, a very broad sense of humor, and I'm likely too passionate for my own good.
Herein you'll find animals (especially creepy-crawlies), nature, science, art, some of my own photography, and occasionally a scattering of personal posts.
I'm an avid reader and music-listener, so suggestions are always welcome (you can check out my last.fm if you're interested).
I source all of my own posts unless it's my content, in which case I tag it "personal."
But that tag is littered with a bunch of other, boring things as well, so peruse with caution.
