Tail sheath acts as a cell membrane to the sperm.
how the sperm cells structure is linked to the cells function, the tall sheath?
The function of the myelin sheath is to insulate the axon of the neuron. When there are gaps in the sheath, known as nodes of Ranvier, the nerve impulse can jump from gap to gap, thus increasing greatly the speed of conduction of the nerve impulse. This is known as saltatory conduction.

It is used for protection against the outside environment
Since Fucus lives in intertidal regions, the gelatinous sheath probably prevents desiccation.

On the belly. It's where the umbilical cord used to be when she was a calf. It's also located where the sheath and urethra is on bulls and steers.
