Scaphitids are a group of heteromorph ammonites that were around during the Cretaceous. While many groups of these relatives to squid and octopus were found, it’s highly speculated that this particular family was the last group of ammonites to ever exist, only going extinct a few million years after the demise of the dinosaurs. Like many deep-sea cephalopods today, these creatures are bioluminescent, using their lights to attract a mate for the final act of their short lives.

Tonight, even in the deep, there is light. Glowing ammonites rise from the abyss. Ammonites are mollusks, related to octopus and squid. These scaphitids are no bigger than a human hand. For weeks, they’ve been gathering in the coastal depths. In the deep, these lights may help lure planktonous food, but tonight they serve a different purpose. They’ve been drawn to the surface to mate, and soon there are thousands in each school. Neighbor triggers neighbor, creating waves of bioluminescence. They have complex nervous systems, controlling light-producing cells called photocytes. The males jostle for a place around the larger females. Clues from their displays tell her who’s fittest and who is the best mate. As couples entwine, they coordinate their light displays. If he can’t match her precise rhythm, he’ll be rejected. But there is perfect synchrony. This pair will now spawn and help produce the next generation. After fertilization, the females enter the shallows to release their eggs. As with most cephalopods, breeding is the final act of their short lives. By morning, these lights will have flickered and died. This magical night will be their last.

Globidens! One of those extinct animals that are weird enough that people know its name despite no big media appearances, well until today of course. Sure it doesn't look as weird with the skin on it, but the design still slaps.

My beloved Ammonites make a return, again thanks for specifying the genus names this time around! I also appreciate the little factoid on their ecology with the streamlined shells, though not sure that common name will stick.

An overall great scene, mixing what we know (Globidens had broad teeth) with what we suspect (they specialized in hunting ammonites) and some healthy speculation (surplus killing).

Why's the Ammonite's death so dramatic though? Trying to make me cry?

I appreciate that the scene doesn't just end there, we get to see the Ammonites reach their nursery and lay their eggs. If you include the Scaphitids from the first season, you could stitch all the Ammonite scenes together and showcase their whole life cycle!

This is perhaps the strangest thing I've ever written but if you're a fan of nature docs, the new Prehistoric Planet series on Apple TV+ has this section in the first episode talking about mating rituals of scaphitid ammonites that reminded me a lot of Jily, because they have these fantastic bioluminescent light displays that they're meant to coordinate with each other perfectly to show compatibility but then they also die young after producing offspring. Just an odd thought that struck me!
