The effect of gravity is lessened in water, mainly due to buoyancy. Gravity applies the same force to us in water as in air; the difference in the perceived force is because gravity is also pulling on the water as well. That's why aquatic animals tend to be far bigger than land animals, water supports the extra weight. For example, blue whales can weigh up to 160 tonnes, while the biggest sauropod weighed around 90 tonnes.
