We've got the answer to this and we'll make it snappy! The average bite force of a common snapping turtle is 209 newtons.
The common snapping turtle is an omnivore, but are known for being great ambush predators. They eat invertebrates, frogs, fish, snakes, smaller turtles, small mammals and even birds.

Our campers spotted a snapping turtle this week and it peaked our curiosity! For this we ask what is the average bite force of a common snapping turtle?

We've been around since the 1960s, so yeah, we've got an interesting collection.
Beautiful blue skies and the bride & groom side by side☁️🤍

The answer is here. Cicada nymphs feed off of tree roots! After 6 to 10 weeks the nymphs hatch and fall to the ground where they burrow into the ground to get to the sap in tree roots. Cicadas spend most of their life underground. They can stay in this dormant phase anywhere from 2 - 17 years before they emerge.
There are over 3,000 cicada species that have been split into two groups, annuals and periodicals. Annual cicadas make up most of the group and they emerge at different times throughout the summer while periodicals all emerge together in broods. A group of cicadas can be called a cloud or a plague. The buzzing sound they make is actually the male's mating call!
