5 ingenious defense mechanisms that exist in nature


There are many creatures in nature that have developed ingenious defense mechanisms. Look:

1 - The lizard that expels blood through the eyes

The lizard of the species below- image Phrynosoma cornutum - In addition to having horns, developed a defense mechanism beyond unusual. This reptile, no larger than 60 centimeters in length, is capable of throwing blood through the eyes to scare off its predators.

O P. cornutum It has two muscles that protect the major blood vessels that feed your eyes. When the defense mechanism is “triggered”, these muscles contract by breaking the vessels and splashing the blood against the predator. In addition to this unexpected jet scare the animal, the blood contains substances that help repel attackers.

2 - The Wolverine Salamander

Salamanders aren't particularly scary animals - take a look at the picture above and tell us if these pets are scary? However, those of the species Waltl pleurodeles (same as in the photo) have a very aggressive defense mechanism: when they feel threatened, they turn to Wolverine! Well, sort of…

These amphibians are able to project their pointed ribs out of the body, and worse yet they still produce a poisonous substance that is released by the skin. And this, in combination with the “thorns,” forms an efficient weapon that, while painful, can even be deadly to some predators.

3 - The bomb ant

As with bees, ants also play different roles in their colonies, and when the security of the group is threatened, the animals unite to attack the invaders. However, ants of the species Camponotus saundersi they go further than just using their jaws to chase away predators. They turn into suicidal warriors and explode.

The workers of this ant species have glands that extend the length of their bodies and are filled with a sticky substance that, besides being toxic, has corrosive properties. When the C. saundersi if they feel threatened, they contract their abdominal muscles to basically explode their bodies and cover the predators with their poison, thus protecting the colony. Heroic defense mechanism, don't you think?

4 - The millipede that shines in the dark

Some animals, as you know, take advantage of their lush coloring and eye-catching designs to scare off predators. However, this trick is not very useful for creatures of exclusively nocturnal habits, such as the millipedes of the genus. Motyxia. And that's why they use bioluminescence as a defense mechanism - and a pinch of cyanide, to be sure.

Because these arthropods only come out at night, when a predator approaches, they begin to glow and expel cyanide - and other toxic substances that make them rather unappetizing - through pores that are scattered along the sides of their bodies.

5 - The sea cucumber that ... Evacuates your guts?

Everyone has their strategy to scare off predators, doesn't it? So while some weep tears of blood, turn into thorny creatures, commit suicide or play in the dark, there are those who expel their internal organs to frighten - or amaze! - enemies such as sea cucumbers.

Although it seems that the sea cucumber in the video above is "defecating" the gut, in fact it is employing a mechanism called evisceration in which it expels its internal organs through the anus to defend itself. It turns out that their viscera are toxic and - more than properly - have filamentous shape, so their predators can die if they get caught in this tangle. Ingenious, don't you think?
