The great prey of the

The animals such as archery fish, velvet worms, prawn type . all equip themselves "great way" to hunt from afar to survive .

To survive in a dangerous animal world, each species needs to equip themselves with appropriate survival skills. Many species have chosen to evolve to become "gunners", specializing in remote attacks instead of the battle of "leaf-armor" to deal with their prey.

1. Fish archers - shoot accurately bait up to 2m

Archery fish is the nickname of the pompano , the scientific name is Toxotidae . This family of fish consists of 7 species, distributed in the Indian Ocean and Pacific waters.

Archers possess special mouths and keen eyes

This is the most formidable gunner of the animal world because of its ability to accurately shoot prey up to 2m away - a distance 10 times larger than the body length less than 20cm. Archers often swim and observe insects and small animals on branches near the water. After that, they will gently approach and defeat the prey.

With a specially formed mouth, archery fish can utilize the dynamics of water to create spray force. Specifically, it adjusted the velocity and shape of the jet of water sprayed in the air, creating a flow of water with force 6 times the force of the jaw muscle. They can even estimate the weight of their prey to use the right amount of water, which helps them to be effective and still effective.

This spray can easily shoot prey that is sitting on the tree and falls on the water. The rest is simply swimming and "cup".

2. Chameleon - catch prey lies 1.5 times more than the body length

Chameleon is one of the top assassins, likened to the small animal ninja world. Not only is it possible to disguise 'paradise of paradise' to deceive the enemy, the chameleon also possesses a very dangerous remote attack weapon, that is the tongue.

The attack with the tongue is fast, powerful and amazingly accurate. By using high-speed video and X-ray film, two Dutch biologists calculated the tongue of the chameleon rushing out of its mouth at speeds of up to 6m / s. It can catch prey located farther than 1.5 body length.

Assassin with a monstrous tongue

They also found that the lizard's tongue accelerated from 0 to 6m / s in about 20ms (milliseconds), so fast that it did not follow the general vital energy rules in muscles. Until now, scientists have not explained this extraordinary "tongue-thrust" mechanism.

In addition to skills such as good swimming, superior tree climbing, body discoloration and especially stereoscopic eyes with independently rotating pupils, the chameleon has a wide range of views. It can be said that chameleon converges almost full of elements of an ideal assassin.

3. Velvet worms - soft body assassins

Velvet worms (scientific name Onychophora ) are a predatory worm at night according to ambush tactics. The velvet worm's body is full of liquid, surrounded by a thin layer of skin. They move very slowly and often hide in the floor of litter on the ground.

They often linger for quite a long time before acting. Velvet worms have poor eyesight due to their activity mainly in the dark, but in return they have very powerful 'radar' beard, which can identify small movements of prey.

Under the pair of antennae is also equipped with '2 glue guns' - this is the main weapon to catch their prey. When choosing the right time, they shoot glue towards the prey. This secreted liquid quickly dries and shrinks, capturing the prey. The more bad guys try to escape, the more sticky they become.

With this technique, velvet worms can destroy insects larger than your body many times. Although the shot was not too far, almost every glue shot was a successful one, so velvet worms were also dubbed the "soft body killer".

4. Knocked shrimp - kill the bait with bubble bursts

Knocked shrimp (Alpheidae) or also known as gun shrimp, shellfish. One of the highlights of this species is that they have asymmetric pairs and extremely special uses.

The majority of knocked shrimp is found in tropical and temperate coastal areas. They live in caves dug under the reef roof. It is also the ambiguity of shrimp type.

The bigger one is the unique sound gun in the animal world. By looking at the prey, by clamping it further, they create an explosive air balloon with pressure up to 80 kPa at a distance of 4cm from the distance. Air bubbles travel at 27m / s and produce explosions of up to 218 decibels, which is enough to kill small fish.

Some species of shrimp knocked down and one of them was Goby. They live and support each other. Specifically, they share their caves for gobies, in exchange, gobies will receive the task of guarding the cave due to better eyesight. When there are 'enemies', the goby will swing the alarm to the two so they can hide deep inside the cave.

Knocked shrimp also have the ability to recreate weapons because when the larger one is cut off, the smaller one will grow into a bigger one, the more will be smaller.
