This is very fascinating (to me, at least). These organisms are so simple that you can probably make a map of every cell in their body, and yet they’re still almost unfathomably complex if you look closely enough. It makes me wonder if some ancient organisms like dickinsonia were some form of giant placozoan-like thing. That’d be weird to imagine, a meter long, more organized cousin of the placozoa. It’s also fascinating to me how similar those crystal cells seem to some structures I’ve heard of in jellyfish that fulfill the same function! They’re kinda creepy to me in how they effectively walk on their cilia, are microscopic saline hot pockets and can tear themselves apart to reproduce. At 3:50 though, that looks a lot more like an illustration to me than an electron micrograph… my only other complaint is that this video isn’t longer!
