What animal is starfish's nemesis?
The nemesis of the starfish: the wonderful "cannonball fish".
The cannonball fish has a pair of hard teeth, and many fish are afraid of it, but its favorite food is the starfish and sea urchin. The mouth and eyes of the cannonball fish are very far apart, which was formed over the long years of evolution, in case they were stabbed in the eyes by sea urchins and starfish covered with long spines and spiny skin while feeding. When the cannonball fish is pitted against the 30-centimeter-long spiny sea urchin, which has lead-covered spines, it takes a bit of brains.
The sea urchin is covered with thorns except for its mouth, and hides its mouth at the bottom of its body, so that the enemy cannot get out of its mouth. In order to enjoy the delicious sea urchin juice, the cannonball fish is skillfully tactical. It takes a sip of water and squirts at the urchin so hard that it turns it upside down, and then strikes at the unguarded mouth.
If this fails, it bites a long thorn on the urchin, pulls it from the bottom of the sea to the surface, and then releases it. When the sea urchin sinks, it is already waiting at the bottom of the sea; When the sea urchin sinks to the bottom of the sea, it can bite into the mouth of the sea urchin and feast on a delicious meal.
