Burrs, spikes, bristles, and bristles in animals all contribute to defense. They may cause irritation or pain, or make it difficult for the animal to be swallowed. Among these bristle-haired animals are many glitched and poisonous animals, which they use in this way to protect themselves from predators.
Thorny caterpillars
For example, different species of caterpillars have burrs on their bodies that make up their defense system. This glitch can harass the attacker. Some varieties of burrs are also linked to toxic glands. These burrs not only sting predators, but also inject venom. Just by touching a caterpillar, predators are often stabbed. Some caterpillars will arch their bodies and insert burrs into the attacker's body.
The saddleback thorn moth caterpillar is a spiny brown caterpillar with a green "saddle mattress" on its back. When its burrs are touched, the burrs pierce into the predator's skin. At this point, the tip of the burr falls off so that the venom flows down the hollow burr from the caterpillar. The saddleback thorn moth caterpillar grows in the eastern United States, and its burrs cause pain and swelling in the injured area, as well as nausea.
River beetle caterpillars are also poisonous burrs. Furry caterpillars look soft and touching, but their powerful toxic properties cause severe pain and swelling. Some of the caterpillars in South America are so toxic that they can temporarily paralyze people.
In Brazil, these caterpillars are called "fire beasts" because of their terrible burrs. Another South American caterpillar, the giant silkworm moth larvae, whose burrs can kill people, most insects are not toxic, the giant silkworm moth larvae are an exception.
Stingrays defended with spines
Some marine life also grows poisonous spines, such as stingrays. Stingrays have flat bodies and are close relatives of the stingray. They hunt clams, worms, and other shallow seabed prey. When resting, the body is often half-buried in the mud and sand. The stingray's tail has a sharp needle that is embedded in the edge of the body like a serration.
Stingrays use these stingers to defend against predators, such as sharks. A frightened stingray will swing its prickly tail and stab its enemies through its back. People who get to it will also be stabbed. Some sea urchins and crown of thorn starfish also rely on sharp stingers for defense. The fire stingray is covered with hollow bristles, which easily fall off and become embedded in the predator's skin, allowing venom to flow into the predator's body. Because of the burning pain that can be felt after being stabbed, it was named a fire stinger. They warn by shining bristles.
Thorny sea urchin
The sea urchin is a prickly needle pad at all times. The spines of the sea urchin also penetrate the predator's skin and then fall off. The poisonous long-spined sea urchin is injected into the predator through the venom flowing from the broken thorn,
Injured him. Some of the spines are wrapped around a toxic cortex, which emits venom when pierced into an animal's body. Sea urchin relatives, crown-of-thorn starfish, also deliver venom in this way. The sea urchin can sense light and shade, and it can pinpoint the attacker and then aim the needle in this direction. The most toxic sea urchin is a sea urchin, and its needle is not toxic, but in its needle hides many sets of tiny toxin jaws.
Other animals with stingers
There are also some marine life fins with poisonous spines. Similar to stingrays, the needles of these fish are used only for defense. Growing on the Shores of the United Kingdom, the bass is adept at hunting in shallow sands. The fish has poisonous spines on its hind fins and gills. They don't use these stingers when catching shrimp and small fish that swim around. However, for attackers who try to eat themselves, the perch will show these weapons.
Poisonous toads nest in the warm, shallow sands of Central and South America. Similar to perch, they show off the stingers on their backs and gills. While they lurk and wait, ready to fish with their teeth-filled mouths or other small prey, their earthy brown and brown and gray colors help camouflage themselves, with hollow needles used only to inject venom into predators.
Another type of fish that is good at camouflage in shallow waters is the slow-moving stone fish with warts on the surface. Stonefish live in parts of the Indian and Western Pacific Oceans, and their venom is the most toxic to fish. When the stingers of the dorsal fin are pressed, the stone fish releases venom. Venom shot out along the grooves on the spines, injecting into wounds punctured by sharp spikes. People can get stabbed when they accidentally step on a stone fish. Sharks and stingrays that open their mouths to bite stone fish can also be stabbed.
Not all poisonous fish are slow to move and live on the ocean floor. The fancy lionfish is brightly colored and has huge fins. The lionfish swimming among other reef fish are a beautiful sight to behold. However, its beautiful fins have poisonous spines. Lionfish use these stingers for defense. It will turn around and face the predator and unfurle its prickly fins as a warning. There are about 1200 species of venomous fish in the world that are more than twice as numerous as venomous snakes, and they use stingers to defend against predators, and most of the poisonous fish are far more poisonous than venomous snakes.
