What does the speaker say about the skin of starfish? [br]
Welcome to our aquarium. As we begin our tour, the first animal we will see today is the starfish. You probably have seen pictures of the starfish, but in a few minutes you will see some live ones and learn a little about their structure. First of all, starfish are not really fish, they belong to the family of echinoderms which are spiny skinned sea animals, (17)that is, their skin is covered with thorny bumps. Most starfish have five arm-like extensions on their bodies. And so they look like a five-pointed star. But some other kinds have as many as 40 or more arms. Starfish, like other members of the echinoderm family, have what’s called radial symmetry.(18)All that means is that the body part of these animals are arranged around the center, kind of like spokes of a wheel around a hub. One of the special features of the starfish is that(19)it can drop off arms as a defensive reaction, to get away from an attacker, for example. They can then grow new arms to replace the old ones.
选项
A、It generates a new one.
B、It cannot swim.
C、It is easily caught.
D、It dies soon afterward.
答案
A
解析
情景事实题。根据句(19)可知,导游提到,遇到袭击的时候,海星可以自断臂膀作为防御行为来躲避攻击,而且能长出新的臂膀来代替旧的。因此A为正确答案。
