2. Seagulls: In addition to eating fish, shrimps, crabs, and shells, seagulls also like to pick up leftovers discarded by people on ships, so seagulls are also nicknamed "harbor cleaners".

They are almost a common sight around ports, docks, bays and ships.

There will also be seagulls following the ship's route. Even walking on the beach at low tide will startle a group of seagulls.

3. Moths: Except for a few species of adult moths that suck juice, most adult moths do not harm crops, while most of the larvae harm crops, fruit trees, and forest trees.

Therefore, people have used the "chemical communication" characteristics of moths to isolate and determine the structures of many moth pests' sexual pheromone, and artificially synthesized them to trap and kill male moths to achieve the purpose of biological control.

4. Dung beetle: The scientific name of Dung beetle is dung beetle, also known as dung beetle, push pill, dung cow, dung rolling cow, dung rolling man, etc. Wherever there are dung beetles, the excrement will be cleaned up.
