Hello folks who think the difference between a good and bad day is whether the cockroach is walking or flying,
Dragonflies and Damselflies might be close cousins but Damselflies are smaller in size and weaker fliers.
One way to tell these two apart is by looking at them while at rest. Dragonflies hold their wings just like planes as shown below.

Most Damselflies fold their wings while at rest as shown below.

Another interesting thing one can tell by looking at these creatures is their gender. Dragonflies and Damselflies have primary and secondary sex organs.

Males can be differentiated by looking at the underside of their second segment. If it has a bulge it houses the secondary genitalia as shown below. Females don't have the bulge under their second segment.

People think frogs have these incredible leg muscles that they use for jumping their way out of trouble, which were built by doing squats at the gym everyday.
Turns out the people wearing lab coats like to burst our bubbles all the time and they say that it is the tendons that are responsible for this amazing ability, not the muscles.

Just before the jump the leg muscles shorten, which then loads energy into the tendons which recoils like a spring propelling the frog into the air.
Here is a Sierran Tree Frog who got fed up of me asking if it agrees with me that Earth is flat.
