Cuttlefish are intriguing little animals. The cut tlefish resembles a rather large squid and is, like the octopus, a member of the order of cephalopods. Although they are not considered the most highly evolved of the cephalopods, they are extremely intelligent. While observing them, it is hard to tell who is doing the observing, you or the cuttlefish, especially since the eye of the cuttlefish is similar in structure to the human eye. Cuttlefish are also highly mobile and fast creatures. They come equipped with a small jet located just below the tentacles that can expel water to help them move. Ribbons of flexible fins on each side of the body allow cuttlefish to hover, move, stop, and start. _____________________________________. The cuttlefish is sometimes referred to as the “chameleon of the sea” because it can change its skin color and pattern instantaneously. Masters of camouflage, they can blend into any environ ment for protection, but they are also capable of the most imaginative displays of iridescent, bril liant color and intricate designs, which scientists believe they use for communication and for mat ing displays. However, judging from the riot of ornaments and hues cuttlefish produce, it is hard not to believe they paint themselves so beautifully just for the sheer joy of it. At the very least, cut tlefish conversation must be the most sparkling in all the sea. Which of the following sentences, if inserted into the blank line, would best sum up the first paragraph and lead into the next. a. The cuttlefish can be cooked and eaten like its less tender relatives, the squid and octopus, but must still be tenderized before cooking in order not to be exceed ingly chewy. b. On a scuba dive when you’re observing cuttlefish, it is best to move slowly because cuttlefish have excellent eyesight and will probably see you first. c. Cuttlefish do not have an exoskeleton; instead, their skin is covered with chromataphors. d. By far, their most intriguing characteristic is their ability to change their body color and pattern.
