Snake carnivores mainly catch "live food", such as mussels, mice, loach, eel, birds, earthworms and insects. Snakes eat a lot and can swallow twice their own weight at a time;

After a full meal, you can 10 days or even more than half a month without eating. July-September is the most frequent period of snake predation, and May and 10 are the peak periods, which is related to entering the breeding period and accumulating nutrients in the body for the winter.

Hunting is not to kill prey with venom, but to entangle prey and suffocate it. Unlike the reckless black cobra, the boa constrictor is an opportunist, paying attention to methods and scheming.

It often dives into the shallows and waits for its prey. It will first detect on the surface of the water and then return to the bottom of the water to wait. Its unique hunting skills are amazing. For example, killing wild ducks on the water, it quickly bites wild ducks with its powerful jaws, drags them into the water, and then wraps itself.

Extended data:

The severe cold of 0℃ is the deadly low temperature of snakes, so when the temperature drops below 13℃ in late autumn, you must find various underground caves to hibernate. Take Beijing as an example. Although the average surface temperature in May 438+10 is as low as -5.4℃, the temperature at the underground 1.6 meters is still 7.5℃. ..

And the temperature changes very little, which is very suitable for snakes to hibernate. This ecological rhythm of snakes is due to the fact that winter in China is the coldest area in the same latitude in the world, so snakes hibernate for the longest time, the deepest in the ground, and the southernmost border of hibernation. Almost all snakes in South China don't hibernate.
