Why do sea divers and astronauts need to wear special suits?
Both astronauts and sea divers wear special sits because they travel into atmospheres that are strange to our bodies. Our bodies were not built to stand extremely deep waters and outer space. The suits protect them as they go about their business in those places.

Why divers wear special suits when they go deep sea?
for protection, as astronauts need to wear space suits to do space walks. Humans are fragile beings. Our skeletons and bone structure can only work in a narrow range of pressure around the atmospheric pressure [~1x105 Pa at sea level] -- we have adapted to earth's atmosphere. In deep seas, the human body will encounter a pressure [Pa], in addition to atmospheric pressure, equals to rho*g*h, where rho = water density [~ 1000 kg/m3]; g = 9.8 [m/s2]; and h is the water depth [m].
Name three types of special equipment astronauts need to work in space?
containers, space suits,
Why does diver need a special breathing equipment but fish does not?
