  • I am currently looking at a number 7 to your list. The Royal Garrama is a fish native to reefs in the western pacific. They often live in caves or overhangs and hunt by perching above their hunting ground upside-down on the ceiling, like a hawk on a telephone wire, but upside-down. The one I keep in my reef tank actually spends 90% of his day upside-down or at an angle not upright. He acts like a astronaut in space rotating on his own axis. I also have freshwater fish that make noise audible from their aquarium across the room

  • The horseshoe crab has been living for millions of years on Earth doing its thing undisturbed. Then humans evolve and annihilate the poor thing. It’s used for fish bate, it gets bled so we can make vaccins from its blue blood, its breeding beaches are being destroyed... This awesome living fossil has become an endangered species. Maybe a video about that topic could be interesting?
