Big snakes: pythons, boas and anacondas, and how big they really get, sentence 12
Constrictors coil around prey and tighten each time it breathes out; scientists found the squeeze mainly stops the blood flowing, so the prey faints within moments rather than being crushed.
Who acts: Constrictors, reward, scientists, squeeze, blood, prey · What happens: coil, tighten, breathe out, find, stop, flow · To what, where: prey, time · Speech: someone speaks here
This is a sentence of the lesson «Big snakes: pythons, boas and anacondas, and how big they really get» of the biology course of Mova's primary school.
