Conceited shield fish.

In the Atlantic Ocean, there is a shield fish. It has a hard shield-like shell on its head. When in danger, it immediately stands up as a shield to resist the enemy.

The shield of the shield fish is so hard and hard that it is really invulnerable. It thought it was great, proud of its own hard shield, and it was so proud that it rampaged through the sea, not caring about anything. Once, a fish with a mouth several times larger than it swam over.

The shield fish thought: Everyone knows that the edge of our shield fish is sharp, and if you swallow it, you will be pierced in the belly and die, who would dare to swallow me easily. It didn't care.

However, the big fish did not seem to know any of this and rushed towards it. The shield fish shouted loudly"Hey, don't eat me, you don't want to live if you eat me!

The big fish was willing to listen and swallowed it at once.

Naturally, the big fish was pierced in the belly by the shield of the shield fish and died, and the conceited shield fish also lost its life because of this.

The fish is just a shield, and the pointed thing in front of the shield is also a sacrifice.

As the title ,An ancient fish with a head shaped like a shieldScientific name.

Eugaleaspidae of the family Eugaleaspidae DunyuExtermination of the true armoured ichthyfish

The picture below shows the dunyu longiforus [fossil species].

The posterior supraorbital canal and the middle dorsal canal are successively transitioned, and the two sides of the posterior end are combined in a "U" shape, and the lateral dorsal canal only emits 3 lateral transverse tubes. The new species lacks an inner horn, a feature that was previously found only in the genus Euarmouridae in the family Euarmouridae. The horns extend posteriorly, spiny or leaf-like; The widest part of the head carapace is located before the end of the horn, and the width-to-length ratio is less than; The end of the middle dorsal foramen extends beyond the posterior edge of the orbital foramen. The characteristics of the new species that distinguish it from the Xiushan shield fish (dunyu xiushanensis) are:

Individuals are larger, with a head carapace longer than wide; horns spiny; The orbital foramen is relatively anterior, and the ratio of the length of the anterior orbital area to the posterior orbital area of the cephalic carapace is less than that; Polygonal tumor, larger.

The shield fish lives in the Atlantic Ocean, a bit like the carp we are familiar with, except that it has a clamshell-like hard shell on its head, which is shaped like a shield, and this hard shell is so hard that it cannot be pierced with a sharp and sharp knife. The shield fish has a hard shell on its head, and it is as formidable as the ancient shield-wielding soldiers, and the fish whose strength is larger than it can only push its shield to swim around in the water, and it cannot hurt it at all. If you come across a fish with a big mouth and swallow it in its stomach, the shield on its head can cut through the stomach of the largemouth and cause the largemouth to die with it, so no fish dares to touch the shield fish.

The fish is just a shield, and there is a pointed thing in front of the shield.
