First, we should define symmetry. Symmetry is the arrangement of body parts so they can be divided equally along an imaginary line or axis. In marine life, the two main types of symmetry are bilateral symmetry and radial symmetry, although there are some organisms that exhibit biradial symmetry (e.g., ctenophores) or asymmetry (e.g., sponges).

Bovril is the trademarked name of a thick, salty beef extract, sold in a distinctive, bulbous jar. A spoonful of the semi-liquid paste in hot water makes a savoury drink. It can also be used as a flavouring for soups, stews or porridge, or spread on bread, especially toast.ut what I loved most to do with Bovril was spread some on a slice of well buttered bread, fold over and eat. I guess a Bovril Sarnie (sandwich) at that time would rate about as popular with kids as the Peanut Butter sandwich here in the States.
