The Java programming language also provides a do-while statement, which can be expressed as follows: The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top.
Vomeronasal organ. The vomeronasal organ (VNO), or the Jacobson's organ, is an auxiliary olfactory sense organ that is found in many animals. It lies close to the vomer and nasal bones. It was discovered by Frederik Ruysch prior to 1732 and later by Ludwig Jacobson in 1813. This organ is the sense organ involved in the flehmen response in mammals.
[Click on photo for larger picture]. This is the organ that generates the signal. It is a modified muscle. To receive electric signals, either from other fish or from echoes of its own discharge, the Elephant Nose fish has three different types of receptors. These are the mormyromasts, the knollenorgans, and the ampullary receptors. The mormyromasts are the organs that detect the echoes of the electric organ discharge. They are what enable the fish to navigate in murky water and find prey. The knollenorgans detect the electric organ discharge of other elephant nose fish, and thus aid in communication and finding mates.
