in mid afternoon, the group is found on the tent undersurface, each caterpillar hanging from the tent by a few of its legs. Propose a hypothesis to explain this behavior.

Mammals have a four-chambered heart, with two ventricles and two atria. So do birds, alligators, and crocodiles, but other living reptiles iring al- have a three-chambered heart, with just one ventricle. Paleontologists deb whether dinosaurs had a three-chambered or a four-chambered heart. Long-necked sauropod dinosaurs could have had unusual circulatory demands because their head may have been raised far above the heart. The farther the head is above the heart, the greater the systolic pressure needs to be for blood to reach the brain. For example, the closed d dinosaur Brachiosaurus may have carried its head as much long-necke as 6 m (20 feet) above its heart. It is estimated that such an anatomy demanded a systolic blood pressure of 500 mm of mercury for blood to reach the brain! Some paleontologists consider this evidence that dinosaurs had a four-chambered heart that supported a dual circulatony system similar to that of birds and mammals, rather than the three- chambered heart of most nonbird reptiles. Can you explain why?Explanation / Answer
As we know the temperatures fluctuate from freezing to hot, the caterpillars exhibit such behavior to adapt the surrounding environment with changing temperature. This mechanism is called thermoregulation which means maintaining internal body temperature according to the surrounding environment. In the mid-afternoon, the caterpillars try to lessen the body temperature.
Take a bunch of caterpillars in a room and observe the movement of the caterpillar changing throughout the day based on temperature.
