Strange ability of snails

Self-glowing to threaten the enemy, shooting venom into prey, moving quickly or adapting to the living environment are strange possibilities of many snails.

1. Self-luminous snails

Clusterwink snails are yellowish green found in Australia. This snail has a special ability to emit a kind of blue light when disturbed by external influences. So far, Clusterwink snail's glowing ability is still a mystery to scientists. They assumed that this could be a tool to help them alert, contact their fellow humans or cause fears for the enemy.

2. Super hard shell snail

Crysomallon squamiferum, commonly known as scaly leg snails , usually lives at a depth of about 2,400 m above the ocean surface. This snail has a superhard shell made of 3 layers, which helps them withstand strong impacts and avoid enemy attacks, in which the outer layer is made of iron sulfide and the middle porous layer has the function reduce shock. Sophisticated shell construction of snails inspires research for scientists to apply the design of various types of armor in the army.

3. Transparent snail

Zospeum tholussum is a newly discovered transparent snail species in the deepest cave area in Croatia. Due to lightless conditions, they have no eyes and no pigment in the skin and flesh. Zospeum tholussum moves extremely slowly, sometimes only moving a few centimeters in a week. However, they can speed up by 'hitching' mammals or drifting through the cave's drainage system.

4. Fast moving snails

Most snails when encountering enemies often choose to shrink themselves in the shell in the hope of escaping death, due to their particular characteristics of slow movement speed so that they cannot escape. However, conical shell snails living in Australia are an exception. When the enemy is detected, they extend the artificial leg with mucus and jump continuously to a safe place, they can even move extremely fast to hide.

5. Snail releases bubbles

The purple snail Janthina janthina can secrete many layers of mucus bubbles that help them hang upside down and float in the ocean according to the waves. These bubble layers not only help them move but also a tool to help them keep snail eggs.

6. Snails live in bird's intestines

Japanese white-eyed snail is often the food of birds. However, about 15% of the snails after being slaughtered and swallowed by the abdomen are still lucky to survive in the bird's gut. After about 40 minutes after swallowing the prey, the bird will excrete the intestinal food. Following the movement of birds, lucky snails surviving and being able to escape can start a new life somewhere else.

7. Winged snail

Thanks to the small transparent wings, the sea ​​snail Thecosomata can float in the ocean. Although it is a favorite food source for many animals such as whales, penguins and seals, thanks to its rapid reproductive ability, they persist and reproduce in stable quantities. However, scientists are concerned that global warming leads to increased CO2 emissions that will increase the ocean's acidity, causing the snail's shell to crack, deform and dissolve.

8. Snails adapted to the living environment

Lymnaea pereger snail is a popular ventriloquist in the UK, with a special ability to adapt to its habitat. Studies show that when these snails live with fish, they are able to change colors and even hard shells from spiral to round in response to the enemy.

9. Poisonous snails

Ampullariidae , often called apple snail , is one of the most poisonous species. In the eggs of this snail there are two types of poison, especially antinutritive and antidigestive, which cause the eating target to suffer from digestive disorders and cannot absorb the necessary nutrients when eating. The poison in the eggs of apple snails is contained in plants or produced by bacteria, and in the animal world, they are the only species containing this poison.

10. Snail poison discharge

Cone snails possessing powerful weapons is a tooth shaped like a tuber to hunt. When a prey swims close, the cone snails will expand the small tap and release the poison. After hitting the snail, cones use "tuberculosis" to pull prey. This snail can shoot "tuberculosis" containing venom into bait at a speed of 400km / h.
