We haven't even discovered 1% of the ocean, so technically all the prehistoric sea creatures (like megaladons and 80 foot long sea creatures) could still be alive and thriving
I think that magalodons still exist just very very deep in the ocean. I also believe mermaids are. Anyone else see the show on animal planet about mermaids.
I do believe good sir that the last one is the Giant Nope Crab, indigenous to the island of Thatsabunchofnope, I also believe that the "Camel Spider" is also a Nope Spider, and is a close relative of the Nope Crab
the pool IS the manta ray
