I read that some species of crocodilians can take care of their young for as long as a year.

How do parents differentiate their offsprings from other young crocodiles? Smell, appearance, sound?

  • $\begingroup$ Crocodiles have very keen hearing and can hear their babies calling from inside their egg. I believe mother crocodiles recognize the sound of babies after they hatch also. $\endgroup$ – ermanen Jan 20 '18 at 16:32
