Please give me some information about animals

You don't have to come in if you know

Problem description: I would love to know that there is an animal that cannot survive on its own, and that it has to be attached to something or other animal in the outside world in order for it to survive. Otherwise, they will not survive. Or very crippled.

Please think of a few animals that meet this condition. I'd love to know, thank you!

Or plants can do it, with this property. Thank you.

Analysis: Starlings live on the bodies of large mammals such as giraffes, and in some ways resemble parasitism, because they feed on parasites or ticks in the giraffe's fur, and even sometimes the starling greedily feeds on the blood from the giraffe's wounds.

The giraffe is not only an omnivorous animal. They also provide food for their friends, the starlings. The starling rides on the back of a giraffe, like a jockey.

These birds comb the giraffe's mane with their pointed beaks on their side ridges, looking for dander, parasites and ticks – a great way to live. The giraffe's body can be cleaned. Starlings only leave the feast when they feed their young.

They live in groups, and all the adult birds are responsible for nurturing their offspring. With a flick of its wings, the adult bird is ready to nurse the bird. Its work also includes cleaning up the droppings excreted by the young birds.

The ticks on giraffes are easy to carry, but what the starling really needs is blood in its body. Unlike young birds, adult birds can suck blood directly. Starlings can keep their wounds alive for many days, and they compete for delicious food.

Whether or not the giraffe is disgusted by this way of sucking blood, it is helpless about it.

Cuscuta is a very powerful parasitic plant, and most of them are parasitic on crops.

Cuscuta is a parasitic seed plant with slender, filamentous, nearly yellow stems, vestigial leaves, no positive roots, and absorbs water and nutrients from the host by sucking roots. It wraps around the stem of the host plant with a stem, and the growth of the plant is stunted after being damaged, dwarf, yellow, and the plant dies in severe cases.

Parasitic seed plants, cuscuits are also called rootless vines, golden silk vines, and there are 4 common species on ornamental plants: Chinese cuscuta chinensis zamCuscuta japonica choisy, Cuscuta campestris jumker, Cuscuta monogyne vahl

Cuscuta seeds that are wound around the host plant and fall into the soil when they are ripe, or mixed in the seeds of herbaceous flowers. Germination begins at the beginning of the summer of the second year.

Young stems grow very fast, up to 1 2 cm per day, and when they touch the host plant, they wrap around the stems to form suction roots that extend into the host to absorb nutrients. The young stems of Cuscuta continue to spread around, and after establishing a parasitic relationship with the host plant, the lower stems gradually rot or dry up, separating from the soil.

1. Dogs, horses, cows, sheep, pigs, and chickens are called "six animals". Some scientists believe that dogs were domesticated from gray wolves by early humans, and were domesticated 40,000 years ago.
