head

A head is the part of an organism which usually includes the ears, brain, forehead, cheeks, chin, eyes, nose, and mouth, each of which aid in various sensory functions such as sight, hearing, smell, and taste, respectively. Some very simple animals may not have a head, but many bilaterally symmetric forms do, regardless of size.
Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nervous tissues concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head.

Space is very limited and I may not even have space to drill all...

    neagtive head shower pumps

    Does anyone know which negative head shower pump can be fitted almost level with the base of the cold water storage tank? I am looking to try and fit one but I don't have much space. I think Stuart turner pumps normally ask for it to be about 500mm below the bottom of the tank?
