Super Small Squid

“Like a jewel dancing in the water, this baby opalescent squid (Doryteuthis opalescens), called a paralarva, sucks water into the main part of its body (the mantle cavity) and squirts it out a narrow siphon. This swimming motion is called jet propulsion. Watch the two little flaps attached to the top part of its body. Those are its fins — they act like rudders by steering and stabilizing the squid as it moves through the water. Can you think of any other animals that move this way?” — VancouverAquarium
