Green heron (Butorides virescens)

The problem with studying the deep ocean is that humans need light to look at things, the depths of the ocean are extremely dark, and what lives there is accustomed to spending most of its time in that darkness. So when we go down there with submersibles and turn on Big Lights to see, we invariably and dramatically alter what's going on, in the same way that it's generally difficult to observe the natural behaviors of terrestrial animals if you whip out a megaphone and shout HEY GUYS WHAT ARE YOU DOING at them first.

I put this in the comments but feel it needs a reblog- Check out some of Dr Edith Widder’s work on light in the deep sea! Among other things, she used the bioluminescence of stoplight fish to deduce wavelengths which most deep sea animals can’t perceive and used that to create light filters to be able to film with minimal disturbance! And that’s how we got 25 minutes of giant squid footage!!!!

@eddieintheocean

can you put that thing on a leash?

if you are "animal lover" and don't find the beauty and silliness stored in the humble leech then you should try

it’s crazy to me that every seed in existence is a little chemical computer taking readings of temperature and moisture and minerals and all that to see if it’s able to grow yet and they’re doing crazy stuff like going into full dormancy and waiting for species-specific conditions etc etc and some seeds will do this in the size of a dust particle (see: orobanche) and some will pack in extra starch and food and do it in the size of a coconut or something… just dissected this flower seed at work that was a woody two-compartment capsule with one embryo per compartment, the whole seed a little smaller than a dime, and I swear to god it had a full soybean’s worth of embryo and food packed in there. it’s just unfathomable to me

sometimes a seed strikes me as being like a little spaceship with on-board life support and stuff. all that’s inherently certain about a seed’s existence is that its parents survived nearby, presumably, so if all goes well it’ll be set up for some kind of success falling where it falls, but ideally the seed won’t see those exact conditions, because being too close could also hurt the seed’s chances of survival… as could being too far away, like if it ends up in a different habitat or ecosystem and the right conditions never happen. The whole food-on-board strategy was a huge buff when they patched it in after ferns and other spore-bearing plants, but it’s still basically outer space, right? Just deploying a hundred ships to different planets in the same star system, hoping it’s not so different down there that it’s unsurvivable? like every seed is a chance and different plants are putting different amounts of food, effort, and strategy into those chances. so you get a million different seeds from a million different species and they all look and act different from the ground up. you know what I mean, man. you know what I’m sayin
