In the recent past, the Golovadik galaxy experienced a collision with another galaxy, which led to the formation of a long (about 90 kpc) tail from stars and gas. The long tidal tail gives the galaxy a resemblance to a tadpole , where its name comes from.
It is assumed that a head-on collision occurred with a small irregular galaxy , which led to the mutual ejection of the substance of the galaxies. During this collision, tidal forces ejected stars , gas and dust from the spiral galaxy, which formed a bright tail. The irregular galaxy itself is now located at a distance of about 1 kpc from the Tadpole and is visible through it.
If you follow the earthly analogy, then as the tadpole grows, its tail will die off - stars and gas will form into dwarf galaxies , which will become large spiral companions.
