Snails are a common creature in nature, everywhere there are its traces, because of its strong reproductive ability, even its natural enemies birds can not eat the feeling, resulting in now every place with green plants will be snail flooding, and no matter how you manage, there will always be new snails appear in front of your eyes, especially in the early sunshine after the rain, there will always be snails in groups on the grass and green plants, large snails look at people scalp numbness.
These large snails have a resounding name: African snails, this snail belongs to invasive alien species, the earliest can be traced back to the 30s of the last century, in 1930 in the mainland Fujian Xiamen found the first African snail, but the source has been unable to verify, now this African snail has 4 to 5 cm, adult 7 to 8 cm is the most common size. But the largest African snail was discovered in 1978, with a shell length of 27.3 centimeters and a staggering 39.3 centimeters when fully unfolded.
So how can such a large snail, its natural enemies endure that they can grow so big? Are snails' natural enemies only birds? The shell of the African snail is very tough, compared to the domestic snail, its shell can be regarded as a body armor, coupled with a large head, ordinary snail-eating birds can not take it at all, its current natural enemies seem to be only humans, but the natural enemies of other species of snails are not only humans and birds.
Double-disc flukes were recognized a century ago, but it wasn't until 2013 that Polish biologist Thomas Vysorovsky confirmed that double-disc flukes can control the brains of snails, and the favorite of the double-disc fluke fluke fluke family of flukes is amber snails, and the color cerbacetes are also a type of double-disc fluke. The color of the color cymbal fluke is colorful, just look at the color is still a little good, but don't look at it small, it is a parasite that can control the snail brain.
First of all, the color cricketer fluke first enters the snail's digestive system through the snail's food, and then begins to grow by the nutrients in the snail's digestive system, and slowly grows into a long tube, and there are hundreds of tail clys in this long tube, these tail crickets then grow and invade the snail's tentacles, the snail's action speed accelerates, and then the snail's tentacles are not as slender as at the beginning, but become swollen colored tentacles, and will beat, the birds naturally can't stand this temptation, and directly grab the snail and eat it.
But is this the "immortal" color worm fluke? No, its life seems to the bird to be an end, but for the color worm fluke is the beginning of everything, they use the bird's feces to excrete, and plan to find the snail host again, in the bird's feces reincarnated again and again parasitic, cycle after cycle, endless life, it is its existence that led to the snail being controlled brain become a veritable "zombie snail", but also become the world's most terrifying "zombie snail".
