Full-time biologist—part-time cephalopod matchmaker, Richard Ross invites us into his secret home lab where he studies the mating rituals of the lesser Pacific striped Octopus.

To hide in the knobby sea fans they call home, Bargibant’s pygmy seahorses have evolved exquisite camouflage

The Rich Ross centric part:
“When it comes time to mate, seahorses that engage in daily greetings generally extend that ritual into a more elaborate display that ultimately says, “I’m ready!” A few years ago, biologists at the Steinhart Aquarium, part of the California Academy of Sciences, raisedH. bargibanti in captivity for 126 days, and observed the species in mating mode. The interaction appears to go something like this: A male and female first trail each other around the sea fan, getting closer and closer until they’re facing one another. “By some signal, they decide, ‘this is when it’s gonna happen,’” says Richard Ross, a senior biologist at the aquarium. The pair then levitates from the safety of their fan, tails intertlaced, and the female deposits her eggs in about 30 seconds. They descend after that, but may repeat the process once or twice.”
