The big male hairy hermit crabs pick up a new girlfriend almost every day. Then they carry her to a high spot, away from rival males, where they wait until she's ready to mate. Or he sees some interesting food. Or his mind wanders and he forgets to hold on and she drops to the floor.
The hairies aren't as patient as the grainy hand hermits; they'll hold the girl for days.
She's game. I wonder if she was impressed by his fancy pants?
