Even though the male and female of most animals are the same size, there is one creature that shows such a remarkable difference in size between the male and female that you’d never guess they were even the same fish.
The very tiny male angler bites into the skin of the larger female, and soon its jaws become part of the female’s flesh. Then, the bloodstreams of the two fish become connected.
After a while, most of the organs in the male’s body stop working, and he then takes his nourishment right out of the blood of the female!
A female angler may weigh 500,000 times as much as a male!
