However, for three species, observers classified egg flotation parameters into categories . For eight species, egg angle measurements were collected as continuous data while float height measurements were collected as categorical data. We did not uniquely identify eggs or examine changes in flotation scores of individual eggs over time.

How Salt Affects The Flotation Of Egg?
Egg in salt water remain floated, because of higher density of salt water. An object floats only when the weight of the fluid it displaces is equal to the buoyancy force or the force exerted by the liquid. The egg sinks in water because it puts more force on the water than the water does on the egg. So to make the egg float, we have two options ...
