This semi-slug (it has a shell, but it’s too small to retract into it) was discovered in a mountain forest in Sabah, Malaysia. One of the distinguishing characteristics that makes it so unique is that it sports a tail three times the length of its body it's actually the longest bug in the world, which it curls around itself when it’s inactive, kind of like a cat you wouldn’t quite want to pet. It is also a flying frog that changes colors.
Their most curious ability is that the Borneo Hills Ninja slug can shoot calcium carbonate “love-darts” into potential mates. These darts are tipped with hormones that are specially designed to get their targets in the mood for love, with the hope that they’ll forget they were just shot with a spike, increasing the chances for successful reproduction. It's kind of like they are tricking their mates into falling in love with them. They are also called as the "heart stealers".
Without considering their beauty or anything else they get attracted to each other. If something like this happened in the human world, that person would have been in jail for their lifetime. Scientists are still researching about these fascinating creatures. These harpoons penetrate the skin of the female and are said to create a hormone in the female which probably increases the chance of the male impregnating the female.
