Vocabulary Practice - COMPLETION A. Complete the paragraph with words from the box.

Reef squid—like their relatives, octopuses—have an amazing appearance. They can quickly change their physical hide in order to produce from predators. They also use this skill to send messages, they can even produce two messages at the same time! For example, a male reef squid swimming near a female squid can create colorful, attractive patterns on the side of its body closest to the female. On the other side, it shows black and white lines that tell other male squid to stay away.
