Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of __________.
Anettt [7]

Option (B) Habituation is the right answer.

Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of habituation.

<h3>Crocodile and avian mutualism—is it real?</h3>
  • One of nature's best instances of mutualism is the interaction between a Nile crocodile and an Egyptian plover bird.
  • A crocodile will simply open his mouth and wait when he needs to floss.
  • The plover bird will involuntarily swoop down and grab meat scraps from the crocodile's gaping jaws.

<h3>Why do crocodiles develop a habit of approaching the birds that brush their teeth?</h3>
  • It is a phenomenon of evolution that when a bird used to sit in a crocodile's mouth, the crocodile didn't eat it; instead, the crocodile used to allow the bird to sit in the mouth and clean the crocodile's teeth so that they can live longer, whereas the birds could get the free food from the crocodile's mouth.
  • It is an illustration of how the two are mutually beneficial.
  • The same is true now because crocodiles have adapted to the fact that birds will clean their teeth, so rather than consuming them, they ignore the birds.

A vertebrate is a creature with a spinal rope encompassed via ligament or bone. The word originates from vertebrae, the bones that make up the spine. Creatures that are not vertebrates are called spineless creatures. As vertebrates advanced, the undeniably complex structure of the mind gave progressively complex capacity, particularly obvious in the in the cerebral cortex, which is enormously extended in nonhuman primates and cetaceans.
