WebTail- The tail consists of an inner hollow tube which is surrounded by a contractile sheath with 24 annular rings. The distal end consists of a basal plate with tail fibres at each corner. The bacteriophage attaches to the bacteria with the help of these tail fibres. Also Read: Overview of Microbes Bacteriophage Life Cycle WebTail Feathers. The tail feathers or rectrices attach to the fused caudal vertebrae or pygostyle. There are usually 12 rectrices that function primarily in steering and braking during flight. As with other flight feathers, the rectrices have long rachis and, generally, vanes of equal length on both sides of the rachis. Modification of Tail Feathers
