To let the dolphins know when to perform a specific behavior, trainers cue the animal with a visual, tactile, or auditory signal. Dolphins learn to discriminate between different signals. Tail droppers Many lizards can shed their tails by contracting the tail muscles to create a break. When the break occurs, the surrounding muscles separate between the segmented muscle blocks. The discarded tail keeps wiggling for a time, distracting the predator while the lizard escapes.
Some lizards can then regenerate at least part of a new tail.
Draw a cartoon lizard creatively using this adaptation. List the advantages of this adaptation. Hummingbirds move upward, downward, and sideways in a virtuoso performance of aerial acrobatics. These tiny birds can even fly backward. By rotating their wings forward and back in a figure eight, they can hover in midair, feeding on nectar and insects.
