What organ helps crocodiles breathe?
Like all reptiles, crocodiles breathe with lungs rather than gills. Lungs are evolution’s solution to respiration issues faced by the first lower life forms that tentatively crept out of the water to eventually live on land full time.
Do crocodiles have organs?
All crocodilians possess ‘integumentary sense organs’ (ISOs)- that is, sensory cells present in the integumentary layer (skin). The image above shows the head of an alligator with an enlarged view of the sensory pits on the outer edge of the lower jaw.
What body parts do crocodiles use for survival?
Crocodilians can move about on land – with surprising speed, particularly when alarmed or angry – but their bodies are mainly adapted for a life in water. The nostrils, eyes and ears lie along the top of the head so that the animal can hear, see, smell and breathe when the rest of the body is submerged.
Which animal can hold its breath the longest?

Is a crocodile a dinosaur?

How does the respiratory system of a crocodile work?
Respiratory system of a crocodile. The air, still moving in one direction, then flows from the smaller bronchi into the bypassed airway and then out of the lungs, completing a one-way loop. This gas exchange system is much more efficient as it allows more oxygen to be inspired in each breath as it can be stored.
What kind of body does a Nile crocodile have?

How are crocodilians adapted to their natural habitat?
A few reptiles in these groups have developed ways around this problem. For example, the Tegu lizard’s proto-diaphragm allows him to inflate his lungs more fully, while monitor lizards can use their throat muscles to handle respiration during movement. The Crocodilian group includes crocodiles, alligators, caimans and gharials.
What kind of stomach does a crocodile have?
Crocodiles have the most acidic stomach of any vertebrate. They can easily digest bones, hooves and horns. The BBC TV reported that a Nile crocodile that has lurked a long time underwater to catch prey builds up a large oxygen debt.
