Giant African Snails

Humans grow hair, nails due to the presence of keratin in our body. But one thing that we can’t grow is a pair of eyes! However, land snails unlike us, re-grow their eyes, if damaged. 

Most land snails have eyes on the ends of their two upper long tentacles. The head has one to two pairs of tentacles which have the eyes at the tips. These tentacles can regrow if severely damaged and if a snail’s eye is cut off, the antennae can regrow a new eye when the antennae grows. 

Snails don’t have a clear vision, but can detect changes in big and light objects. If you place a finger in front of the snail’s eyes, it can sense it and will instantly retract or draw back its eye into the tentacle to protect itself. 

The Giant African land snail is known to eat more than 500 different types of plants.

Mantis Shrimps

Humans train for years at throwing punches to become good boxers. However, Mantis shrimps have a naturally powerful punch.

Mantis shrimps are found in the shallow waters of the Indian and Pacific oceans. They are very colourful and their size ranges from two to seven inches. They are crustaceans, which means that they are animals with a hard outer shell.

Mantis shrimps can throw the fastest punches in the world. They use their powerful punch to hunt for preys. Their punches can break through crab shells and walls of fish tanks as well.

Their bodies have adapted to throw fast punches. When their upper arms contract, their body’s energy gets stored in a small saddle- shaped part in their body. This acts like a spring that has been compressed. All this energy is released at once, leading the lower arm ahead quickly. Each punch produces small flashes of light, upon impact. These small flashes occur because their claw moves so fast that it lowers the pressure of the water in front of it, causing it to boil.
