The postanal tail in chordates serves various functions, including aiding in swimming and balance, providing propulsion, and assisting in movement and maneuvering in the water. It is one of the defining features of chordates, along with the notochord, dorsal nerve cord, and pharyngeal slits.
The sperm is streamlined with a tail, called a flagellum, that propels it forward. This flagellum moves back and forth rapidly, allowing the sperm to swim towards the egg for fertilization. The structure also includes a head with enzymes to penetrate the egg's outer layer.
Flagellum is a long tail-like structure found in some cells that is used for movement. It propels the cell by whipping back and forth, allowing for swimming or locomotion in liquids. Flagella can also help in the capture of food or sensing the environment.
A sperm cell is an example of a cell that has a tail or more properly a "flagella". Cells with Flagella are also found among all three domains of life - bacteria, archaea, and eukaryotes - but the structure of the appendage is different in each of these domains.

The hydrocarbon tail in phospholipids provides the structure and flexibility to the molecule, allowing it to form the lipid bilayer of cell membranes. This tail is hydrophobic, repelling water and helping to create a barrier that controls the movement of substances in and out of the cell.
Flagellum is a large tail-like structure found in some cells that aids in cell movement by propelling the cell through a whip-like motion.
A flagellum is a tail-like projection that protrudes from the cell body of certain prokariotic and eukariotic cells, and functions in movement.
A fantail typically has 12 feathers in its tail. These feathers are known for their distinctive fan shape, which the bird displays during courtship and when it is excited. The tail's unique structure and movement contribute to the fantail's charm and agility in flight.
Grasshoppers do not have a tail in the traditional sense, but they do have a structure called the cerci, which are two appendages located at the rear of their bodies. These cerci can be thought of as sensory organs that help them detect movement and changes in their environment. Additionally, grasshoppers have a long, segmented abdomen that may appear tail-like, but it is not a tail.
A crayfish has six tail joints, collectively known as the abdomen. These segments, or somites, are often referred to as the pleon and are flexible, allowing the crayfish to swim by flexing and extending its tail. Each segment contributes to the overall structure and movement of the crayfish.
The main function of the tail is to help with balance and coordination, as well as aiding in communication and signaling between animals. Additionally, the tail can be used for defense and propulsion in certain species.

The tailbone, or coccyx, is considered a vestigial structure because it is the remnant of a tail that our primate ancestors used for balance and mobility. Over time, as humans evolved to walk upright, the need for a tail diminished, and the coccyx became functionally obsolete. While it still serves some minor functions, such as providing attachment for ligaments and muscles, it no longer plays a significant role in human anatomy.
Tail stock is a part of lathe ,which is used to support the lengthy job.
No, a human's butt is not a tail. The buttocks are primarily composed of muscle and fat and serve various functions, including mobility and support for sitting. In evolutionary terms, humans lost their tails as they adapted to bipedalism, while the coccyx, or tailbone, is a remnant of a tail structure. Thus, while there are anatomical similarities, they serve different purposes.
