Waterscorpion

Description:

Ranatra is a genus of generally slender predatory members of the family Nepidae, known as water stick-insects or waterscorpions. Their front legs are strong and are used to grasp prey. They breathe through a pair of long breathing pipes extending from their tails. They eat tadpoles, small fish and other insects, which they pierce with their beak and inject a saliva which both sedates and begins to digest their prey. (information from Wikipedia)
