Crocodiles and gharials (large crocodilians with longer jaws) have salivary glands on their tongue, which are used to remove salt from their bodies. This helps with life in a saltwater environment. Crocodilians are often seen lying with their mouths open, a behavior called gaping . One of its functions is probably to cool them down. Q: Lying with their mouths open, a behavior called gaping, probably serves what function for crocodiles? A:
OPTIONS:
