If the specific density(or gravity not sure exactly) of an object is less the the specific density(or gravity?) of the fluid it will float. the more dense an object is the more it sinks this might help shed a little light on the matter

Buoyancy, the tendency to float in a liquid or gas.
Archimedes' principle states that a submerged body is subject to a buoyancy force that is equal to the weight of the fluid displaced by that body. This explains why a heavily laden ship floats; its total weight equals exactly the weight of the water that it displaces, and this weight exerts the buoyant force supporting the ship.
The point at which all forces producing the buoyant effect, or upthrust, may be considered to act is called the centre of buoyancy and is the centre of gravity of the displaced fluid.
When the ship is upright, this point is on the vertical centre line of the ship; similarly the centre of gravity of the ship structure is also on this line. When the ship rolls, the centre of buoyancy moves sideways and the line of action of the buoyancy force, which is always vertical, intersects the centre line of the ship at a point called the metacentre.
For stability, the metacentre must be above the centre of gravity of the ship, irrespective of the position of the centre of buoyancy. In the vast majority of ships the centre of buoyancy is actually below the centre of gravity

buoyancy is a finding of an extraordinary scientist, Archimedes. It is the flowing over of water from its container when a given mass of solid is dropped into that container. Uses to calculate density

The net upward force acting on a body partially or fully immerged in a liquid is known as buoyant force.
A Greek scientist Archimedas told that when a body is partially or fully immersed in water the force acting on it is equal to the weight of the displaced liquid.

when a body is partially or wholly submerged in a liquid, it experiences an upward force or thrust which is equal to the weight of the liquid displaced by the body. the upward force is called upthrust or buoyant force.

the upward force put by the water on the body equal to the water displaced

byoyancy of a material is the ability by virtue of which..it is pushed back to the surface of water...with the same force by which it goes down....henceforth it can be called as the ability to float...

I think it is the ability to float, especially in fish.

bouyancy is just the ability to float.
