The ray fish is a type of marine fish characterized by a flat body and a large fin on the back. It lives near the sea floor and feeds on small invertebrates and small fish. Here are more details about it. from teketrek.
About ray fish
Rays belong to the family Rajidae and belong to the phylum Chordata.
The ray is characterized by a flat and round body, and its size ranges from approximately 20 cm to 2 meters, depending on the type of ray.
In terms of body layers, it is divided into two main layers:
- The upper layer (dorsal): It is characterized by a color that is consistent with the ray’s environment, and is usually dark in color to help blend in with the ocean floor and protect against predators.
- The lower (ventral) layer: It is usually lighter in color than the upper layer, and contains breathing holes.
- These layers help the ray adapt to its environment and provide protection and food. Its flat body shape helps it move easily in the water and blend in with the surrounding environment.
Ray fish food
- Small animal rays feed on crustaceans and small fish, in addition to molluscs, worms, and other invertebrates.

Sections of ray fish
The ray fish consists of several parts, including:
- Head: It contains the eyes, nose, and mouth, and is home to many sensory organs.
- Body: It consists of two main parts: the front part (chest) and the back part (tail). The body contains muscles and internal organs such as the heart, liver, and kidneys.
- Fins: Rays have multiple fins that help them swim and balance, including the dorsal fin, pectoral fin, and anal fin.
- Electrical cells: Some types of rays contain electrical cells that they use for defense and hunting.
- Mucous membrane: The body of the ray is covered with a mucous membrane that helps it move smoothly in the water.
Reproduction in ray fish
The ray fish reproduces through a process of external insemination, where males and females gather to release eggs into the water. After fertilization, the eggs develop into small larvae that become the ray fish. This process is important for the continuity of the species and is affected by environmental conditions according to the following stages:
- Grunt eggs: The life cycle of the grunt fish begins when the female empties her eggs into the water. The eggs are fertilized by the male and small eggs are formed.
- Larvae: When the eggs hatch, larvae appear and begin to swim in the water. This stage depends on microorganisms such as jelly and algae.
- Young fish: The larvae develop over time into small fish. These fish are fragile and feed on small organisms in the water.
- Large Fish: Fish continue to grow and develop until they become large and strong. This stage is considered suitable for mating and reproduction.
- Thus, the life cycle of the grunt fish continues to repeat itself to ensure the continuity of the species. This cycle depends on environmental and nutritional conditions to ensure successful reproduction and survival.
