Life in another gravity planet?

 

What would life look like on a high gravity planet?

Best example, the elcor from Mass Effect:

 

 

On a high-gravity planet, a fall can be fatal, so any life would have to be heavily built and quadrupedal (or more), to ensure a stable gait and a low centre of gravity.

 

High gravity planets would likely have a much thicker atmosphere, so lungs would have to be much stronger to move the air, and hearts would have to be much stronger to pump blood against the greater force of gravity. Veins would probably also have muscles, like our arteries do. Oxygen would likely be much more concentrated, so creatures could become larger.

 

Flying animals are unlikely on a high-gravity planet, unless the atmosphere is thick enough to support their weight, like whales in water.

 

 

Waves on a high gravity planet would be very small, but pack a huge punch. I’m not sure what volcanoes would be like, though they likely wouldn’t erupt until the pressure had reached gargantuan levels, which means eruptions would be rare, but insane
