Here we have a super cute cuttlefish trying really hard to blend in while in a tank with no surrounding objects except one of those plastic trees from a goldfish tank, and I bet it still took you a second or so to realize what it was.  Imagine if this guy was on the reef and needed to hide, think you’d stand a chance of spotting him?  Luckily, cuttlefish are very inquisitive and intelligent animals and I’ve spent hours interacting with them while diving.  They usually appear in a small group and there always seems to be one who is the most daring, coming up to you and turning into strange shapes and moving around you like a flying saucer.  Here is a cool article from NPR about how they assume different “moods” and pick their textures and appearances at will.  LINK
