During mating, the 2 partners take turns fertilizing each others eggs.

Just a reminder that while prehistoric fish are cool, there are plenty of neat babies still around!

can you do one about vampire squids ? 🦑
Vampyroteuthis infernalis or Vampire Squid
It's (very dramatic) scientific name means "vampire squid from hell". However, the vampire squid is not actually a squid! It's actually the only animal in the Vampyroteuthidae family! It's separated into its own family because it can't change color or produce ink. Instead, it turns itself "inside out" (as shown above) to deter predators.
Proportionally, vampire squids also have the largest eyes compared to their body size! They eat mostly zooplankton, marine snow, and other organisms waste. They grow to be about the size of a football and live to be around 8 years old.
There's even evidence that vampire squids have been around since the Jurassic period- almost 200 million years ago!

sturddlefish weren't supposed to exist. they were supposed to be infertile eggs but instead they hatched?? the last common ancestor between surgeon and paddlefish was 180 million years ago- that's like trying to cross a modern human with a platypus (common ancestor ~170 million years ago). it shouldn't have worked
and because the sturddlefish weren't really genetically all there (many of the eggs didn't make it very far into the development) the ones that hatched looked very different from one another
source: wikimedia
specifically, it was a cross between the Russian Sturgeon and the American Paddlefish. if you're thinking "they're both fish though" I need you to remember that "fish" is a SHAPE. just like "tree" and "crab" and "ferret" are shapes. except things have been living in the water much, much longer than they've been living on land, so "fish" have had even longer to evolve away from each other. the last time their common ancestor existed, humans and platypi hadn't even branched off from each other
