Fish Body Parts Game Online

This page features a fish body parts game online. In this game students will learn about the parts of a fish like the fins, the scales, the mouth, eye and more. This game is suitable for homeschooling and classrooms for students in 3rd to 7th grades.


Anatomy of the body parts of fish

Anatomy of the body parts of fish

A basic knowledge of fish anatomy begins with their body structure. The basic structure of a fish is based on a primary structural framework connected to the head at the front of the body and the tail at the back. The spinal column consists of hollow vertebrae that house the spinal cord. The spinal cord is the central control center of the body and relays instructions from the brain to other parts of the body. The brain is also the place where sensory information is processed.

Skeletal muscles are voluntary

In fish, the muscles of the skeleton are all voluntary. These muscles control body movements. These muscles are controlled by the peripheral part of the central nervous system. The muscle fibers are striated, a feature that distinguishes them from other types of muscles. The fibers of these muscles are arranged in different ways to allow them to perform different actions. The smooth muscles are mainly found in the abdomen.

Cartilaginous fish have three specialized organs

Because they do not have bone marrow, cartilaginous fish have three specialized organs. They produce red blood cells in the spleen and in a special tissue around their reproductive organs called Leydig's organ. All cartilaginous fish have internal fertilization, although some species lay eggs and hatch their eggs inside the females. Others develop their young in utero, where the yolk sac develops and provides nutrients to the embryo.

Caudal fin

The caudal fin is one of the most conspicuous appendages of fish. Its movements have attracted the attention of scholars and scientists for thousands of years. In addition to their propulsive properties, fish can actively deform their fins, resulting in various forms of locomotion. The various appendages of fish, such as the dorsal fin, pectoral fin, strap fin, and median cleft, are extremely flexible, and their movements have been studied extensively.

The lungs help fish breathe

Amphibious fish, such as lungfish, have a complex respiratory system with gills and a lung. Lungfish are obligate air breathers, meaning they must regularly surface to breathe. In a tropical climate, the fish dig mud pits to survive. While mud is uncomfortable and low in oxygen, lungfish can breathe at the surface. They are therefore a particularly important member of the fish kingdom.

Adipose fin

Although most ray-finned fish do not have adipose fins, this novel structure is a recent development. Unlike other fins, adipose fins are not structured like an endoskeleton, but have evolved as part of the subdivision of the fin area. They have also been found to be simpler, both in structure and function. 

Lateral line

The lateral line consists of three distinct placodes: the anterodorsal, the anteroventral, and the median placode. The placodes develop from a common pre-placode region and are characterized by the expression of transcription factors and cofactors. The Eya1 and Eya4 genes are expressed in the lateral line placodes of zebrafish, sharks, and shovelnose fish. Two of these genes are expressed in the neuromast and ampullary organs of paddlefish.

Swim bladder

Aquarists may have experienced problems with the swim bladders of their fish. Fortunately, most aquarium fish have a swim bladder with two chambers. The main function of this organ is buoyancy, but it also has other functions, such as producing sound and hearing.
