It also showed signs of adaptations to aquatic life, including a thick and heavy outer coating and dense limb bones that reduce buoyancy so that they could stay underwater, which are similar to the adaptions found in modern creatures such as the hippopotamus.

He reduced buoyancy, and Kon-Tiki began to drop down the face of the dissolving cliff.

Other critical areas such as the rudder, propellers, and bow could not be armored, so damage to these areas could reduce a ship's maneuverability and buoyancy.

The new plans greatly added to the design's complexity, requiring sophisticated pumping mechanisms, while the added weight would also reduce speed and buoyancy.

Knot took a breath and dived-but could not descend low enough until he let out half his air to reduce buoyancy.

Its great disadvantage was that it reduced buoyancy and stability which contributed to excessive heel during turns.

Replies: On the whole, bubbles reduce the density of water and reduce buoyancy.

The feathers of cormorants soak up water and help in reducing buoyancy and thereby allowing the birds to swim submerged.

This is similar to the bones of modern creatures such as the hippopotamus, and reduces buoyancy so that they can stay underwater.

That exhaling before submersion reduces buoyancy.
