Why do plovers clean crocodile teeth?
The plover bird flies inside the crocodile’s mouth, which may seem dangerous for the bird. Food stuck in the mouth of the crocodile can cause infection, and the plover bird’s picking cleans the crocodile’s teeth. Therefore, when a crocodile needs its mouth cleaned, it will open it and wait for the plover bird’s help.
Do crocodiles eat birds?

Why are crocodile bags so expensive?
As a material, crocodile leather is rare and expensive because of limited numbers of crocodiles, their relatively small size and the scarcity of dependable farms and tanning facilities to process and prepare the product for market.
Does crocodile have a tongue?
A crocodile’s tongue doesn’t move. It is held in place at the roof of the mouth by a membrane. Because crocodiles spend so much time underwater, the tongue helps keep the throat closed, protecting the animal’s airway. Unlike other species, the tongue plays no part in feeding.
What animals teeth never stop growing?
Rabbits, squirrels, and rodents have teeth that never stop growing. They have to chew on tough foods like nuts, leaves, and bark to wear down their teeth and keep them from growing too long.
Why can’t adults regrow teeth?
It sounds good in principle, but with each new set, there’s a risk that the regrown teeth won’t line up. So the leading theory is that adult humans can’t regrow our teeth because it was better for survival to only grow one, well-aligned adult set.
What animal can regrow teeth?
Alligators, for example, grow their teeth in sets of threes. This includes a current tooth, a replacement tooth in waiting, and a stem cell that can regrow another replacement tooth if necessary. This process can repeat throughout the lifetime of the animal.
