Failed the college entrance examination and went home to fish

Chapter 146.
After Ye Kai and the others put the fish in place, they continued to sail the boat and continued to drive forward for a while, when they heard the system prompt again.

"Congratulations to the host, there are rays 410m ahead."

Ye Kai quickly said: "Luo Jinshuo, there are rays, please stop for a while."

"Follow the system's navigation and stop when you reach the ray in front. We will be ray."

After Ye Kai exchanged some fishing nets and anesthesia needles, he was ready to catch them. Because there are big and small ones, the big ones are very big, so you need to use anesthesia needles to catch the small ones. Just catch it with a fishing net.

After a while, several people came to the system's navigation location.

When Ye Kai saw that he had arrived at the system's navigation point, he quickly said, "Luo Jinshuo, we're here, you can stop now."

Luo Jinshuo stopped immediately after hearing this.

After you get down, the three of you put on your diving suits and prepare to go down and catch rays.

Skate, an animal of the order Chondrichthyanidae.Rays are found in all temperate and tropical shallow waters except the South Pacific and the northeastern coast of South America.Rays are harmless and bottom-dwelling, often partially buried in the sand at the bottom of the water.It comes in different sizes, with the small ray being only 50 centimeters long as an adult, and the large ray being up to 8 meters long. It has a flat, rhombus-shaped body, and the entire pectoral fins of the fish look like a pair of large wings.

Rays are cartilaginous fish.It has a flattened, diamond-shaped body that is oddly elegant in appearance.The entire pectoral fin of the fish resembles a pair of large wings, and it is like flying when swimming.They have protruding round eyes and two slits in the head through which oxygen-rich seawater enters its body and exits through gill slits on the abdomen behind the mouth.

The stingray's endoskeleton is entirely composed of cartilage, and some parts have a certain hardness after calcification, but it is different from the hard bone tissue formed by ossification.The body surface is covered with scales, which are formed by the ectoderm and mesoderm. Scales and teeth are homologous structures.The mouth is not located at the tip of the snout but on the ventral surface, with a transverse split (so it is called a transverse stoma); the even fins are horizontal; the caudal fin is crooked.The stomach is clearly differentiated, with an independent pancreas and a well-developed liver.There are spiral valves in the intestine.No swim bladder.The gills are very long and extend to the body surface to connect with the skin, so the gill slits open directly to the body surface.The heart has conus arteriosus.The male reproductive duct borrows from the mesonephric duct.A single cloacal pore opens outside the body.Males have copulatory organs called flippers.Oviparous, ovoviviparous or pseudoviviparous, internal fertilization, external development or internal development.The number of eggs laid is small, but the survival rate is high.It has a developed brain and is more advanced than bony fish.The brain is large in size and nerve material appears on the top of the brain.

Ye Kai and the others saw a few big Yao Yuliang picked up the anesthesia needles in their hands and gave these rays a few needles.After a while, three people caught three of them, and the ray moved them to the boat one by one.

The three men helped the rays into the boat, and then continued down to see if there were no other fish.

The body of the ray is round or diamond-shaped, with wide pectoral fins extending from the tip of the snout to the root of the slender tail; some species have a sharp snout, their bodies are flat, and their tails are slender. Several poisonous thorns with serrated edges grow out.

The eyes and blowholes of the rays are on the top of the head, and the bottom of the mouth and nose are formed by the protruding coracoid cartilage of the skull.

The body is monochromatic or patterned. Most species have hard spines or spine-like structures on the spine, and some tails have power generating organs with weak power generation capabilities.As far as we know, all rays are oviparous, and their eggs, also known as "mermaid's purse", are often found on the beach, rectangular, and protected by a leathery shell.Rays vary in size: the small ones are only 50cm in size; the big ones can be as long as 2.5m.

Rays are harmless, bottom-dwelling, and are often partially buried in the sand at the bottom of the water.

When swimming, the pectoral fins make graceful wave-like swings to move forward.

Feeds on molluscs, crustaceans, and fish, and swoops down from above to catch prey.The eyes and blowholes of the ray are on the top of the head, and the mouth and nose are on the bottom side. These are all evolved by the ray to adapt to the bottom life.

Rays are not fierce, and they will not actively attack people, but many rays do not like to swim.

1 million years ago, rays were similar to sharks, but in order to adapt to life under the sea, they hid their bodies in the sand on the seabed for a long time, and gradually evolved into this appearance.There is a circle of fan-like pectoral fins around the body of the ray, and the tail fin is degenerated, like a thin and long whip, moving forward by the wave-like movement of the pectoral fins.Rays usually hide in the sand, but when shellfish, crabs, and shrimps approach, they attack suddenly.Their teeth are like stone mortars, which can grind very hard things. There is a poisonous red thorn growing on the back, and people will die if they are stabbed.Features: The head of the ray is directly connected to the body without a neck.

This kind of fish has a thorn in its tail, and that thorn is very scary, and it will even kill you if you get stuck in it.

This fish is closely related to sharks, although it is not obvious, but they were the same species a long time ago.

Ye Kai and the others continued to look for these rays. In fact, there are many species of rays in this kind.

Dear, because there is another species in it, the electric ray.

An electric ray, an electric ray.The electric ray is about 750px-2m long, with a soft body and smooth skin. The head and pectoral fins form a round or nearly round body disk.A pair of generators, composed of metamorphic muscle tissue, are located in the body disk. The sides of the head can generate electricity for defense and capture of prey. The current emitted by large electric rays is enough to knock down adults.Body disc oval, width slightly smaller than length; tail width shorter, slightly shorter than head and trunk length, longer than body disc, side folds are very low; snout quite long, front end wide and round; snout cartilage soft, slender, central One; the preorbital cartilage is well developed, laterally divided into multiple branches, and the inner side is connected to the base of the rostral cartilage by ligaments; the eyes are small, buried under the skin, and located at the upper corner of the inner side of the jet hole; the jet hole is quite large, oval shape.Distributed in the coastal areas of the Pacific Ocean, Indian Ocean and western Atlantic Ocean.
