Rare giant snails are quite literally both rare and giant. These creatures can grow to the size of a human fist, and only seem to make an appearance when the environmental conditions are just right — namely when the surrounding soil is saturated just enough that one of their favorite forms of prey emerges from the ground: earthworms.
Rare giant snails are so elusive that researchers still don’t completely understand their hunting techniques or how they know when there are earthworms around, but there are just enough specimens in captivity that researchers are able to bear witness to the animals hunting down their favorite prey.
After the rare giant snail crosses paths with an earthworm, there isn’t much the latter can do to evade predation. The giant snail goes into full-fledged hunting mode, revealing its mouth and using it to envelop its prey. While being sucked into the snail’s mouth slowly like a strand of spaghetti, the earthworm is suffocated.
While earthworms are the rare giant snail’s ideal form of prey, the hunter will certainly consider different meals if it can’t find earthworms. These snails have thousands of small teeth that help them obliterate whatever it is they find appetizing, so long as it fits in their mouth.
