I’m sure you learned in school that there is a thriving ecosystem in the deep ocean depths. Far deeper than sunlight could possibly reach, on the frigid desert of the sea floor, various critters survive on whatever sinks down from above, and on each other.
I must admit that my mental image of this habitat didn’t include feeding frenzies. However, one was captured on film by Japanese researchers, showing eels, crabs, and giant isopods (football-sized lice) disposing of a fish carcass.
The time-lapse sequence looks like something out of a Miyazaki film.
Nature is cool. And usually gross.
