Water beetle - an indestructible insect that cannot be eaten

Meet this water beetle. This is a small and black insect that does not stand out for anything interesting or unusual. However, he knows how to surprise. This kid lives by the motto: "Even if you've been eaten, there are at least two ways out!". Yes, the water beetle is not afraid of frogs, because even being "eaten", it will calmly go free through the "back door". Such a ... intestinal water park.
