We were lucky to capture about two young giant pacific octopus larvae in one of our night light adventures. Although it looks more like a squid, it is an octopus. As it gets older the mantel becomes rounded and they spend more time on the bottom.
Just to give you some scale, this little guy is about the length of my pinky fingernail. He will live for 3 to 5 years and get to be about 14 ft from arm to arm.
