Poeciliopsis prolifica, or the blackstripe livebearer, is a species of small freshwater fish in the family Poeciliidae. It is endemic to Mexico.[3] It is a viviparousspecies and the female can have several clutches of young developing internally at the same time, hence the specific name prolifica, from the Latin proles, “offspring” and ferax, “rich, fruitful” in reference to the great number of young produced.

Fish bone is any bone of a fish. Fish bone also includes the bony, delicate parts of the skeleton of bony fish, such as ribs and fin rays, but especially the ossification of connective tissue lying transversely inclined backwards to the ribs between the muscle segments and having no contact with the spine.
Not all fish have fish bones in this sense; for instance, eels and anglerfish do not.
There are several series of fish bones: Epineuralia, Epicentralia, Epipleuralia and Myorhabdoi.

Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. Stains and dyes are frequently used in biology and medicine to highlight structures in biological tissues for viewing, often with the aid of different microscopes. Stains may be used to define and examine bulk tissues (highlighting, for example, muscle fibers or connective tissue), cell populations (classifying different blood cells, for instance), or organelles within individual cells.
An otolith (Greek: ὠτο-, ōto- ear + λῐ́θος, líthos, a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular labyrinth of vertebrates. They have been identified in both extinct and extant vertebrates.[1]Counting the annual growth rings on the otoliths is a common technique in estimating the age of fish. The saccule and utricle, in turn, together make the otolith organs.
