Today we are going to talk about a species of fish that is rather unique: Today’s lecture is about sea horses, if you’ve seen a sea horse, you may have noted that it has a horse-like head attached to its body. The sea horse has a long snout that is good for sucking. Instead of scales like most fish, sea horses have skin that is stretched over bony plates. The body extends to a prehensile tail, meaning that the tail can be used to grasp. The sea horse may grasp sea grass or coral to keep it stable in a moving current.
The sea horse has fins on its back that it can use to propel it through the water. However, sea horses aren’t very good swimmers. They do not move quickly over great distances. The sea horse also has chest fins that it uses for stabilization. The chest fins help the sea horse float in an upright position.
One particularly unique feature of sea horse is that only the male becomes pregnant. The female inserts ripe eggs into the male’ pouch, where they are fertilized. The eggs become embedded in the pouch wall.
选项
A、Propelling it through moving currents.
B、Grasping sea grass or coral to stabilize it.
C、Fending off attacks form predators.
D、Moving food to its mouth, like an elephant’s trunk.
答案
B
解析
本题考查的是事实细节。另外对题干出现的关键词“prehensile tail”可能不熟悉。选项a并不符合题意。选项c和d在逻辑上说的过去,若考生没抓住准确细节的话很容易误选。
