Indian fish has a flat head with a sucker on it. The folds of the sucker are similar to the footprints of human shoes, so its swimming ability is relatively poor. It mainly relies on the sucker to absorb other creatures for activities. When it reaches the food-rich area, it will leave the host to hunt alone, and then attach itself to other hosts to continue its journey. In addition, the owner's leftovers are also their food.
For Indian fish, sucker is the most important tool for their survival. In the eggs laid by Indian fish, the sucker first develops in the head, and then grows teeth and bones. When they are mature, they can choose the host to move. Although Indian fish need a ride, they are also group activities, so there are usually many Indian fish on a main engine, and they only move alone in shallow water.
Indian fish are mainly distributed in tropical and subtropical waters, and are rare in colder high-latitude waters. So on 20 16, after a Qingdao fisherman caught two Indian fish, everyone didn't know this strange marine fish, and it was only after identification that it was called Indian fish. Indian fish has high practical value, which can be eaten, used as medicine and used as ornamental fish. And the aquarium is also very popular because it will be attached to large marine life for travel. In addition, some fishermen take advantage of its ability to suck other fish and use Indian fish as live bait to catch turtles.
This naturally hitchhiking Indian fish can be said to be the laziest fish in nature, but this is also the result of its evolution. Although it doesn't have strong fins, it has a strange sucker, so nature is really "natural selection, survival of the fittest."
