Itty bitty octopi! The "big" one is about two inches tall. The smaller one is less than 3/4 inches.
Note the little suction cups on the underside of the big one's legs!
Here's my theory on the little one: he's a rare four-legged octopus. His parents are hoping the other four legs will sprout at some point. And, of course, like all good parents, they love him anyway.
