The female praying mantis RIPS OFF THE MALE'S HEAD during sex!
Often, the male will try to initiate courtship in secret (technically rape, but in his defense, there's a good chance he's about to become someone's lunch). If detected, the female will kill him and eat him, often by ripping off his head mid-coitus. Upon being decapitated, the male mantis will reflexively tense up and start to deliver sperm more vigorously than before. Afterwords, in lieu of a cigarette, the female mantis will relax by eating whatever is left of her new ex-boyfriend.
Most mantises don't do this, but the most famous species of mantis, Mantis Religiosa (aka the "Praying Mantis"), does this all the time, thus giving the rest of the mantis family a bad name. For some reason, male praying mantises are undeterred by this and they continue to initiate this bizarre mating ritual. The technical term for this process is "Sexual Cannibalism", a fetish that (thankfully) has yet to catch on much among humans.
A strawberry is not an actual berry, but a banana is.
By technical definition, a berry is a fleshy fruit produced from a single seed. The strawberry, however has its dry, yellow "seeds" on the outside (each of which is actually considered a separate fruit). True berries, such as blueberries and cranberries have seeds inside. However, the banana fruit is a berry for the same reason strawberries are not.
There is a theory that strawberries were named by 19th century children who picked the fruit, strung them on grass straws, and sold them as "Straws of berries".
Having blue eyes is actually a mutation. Before the mutation occurred, all humans had brown eyes.
Biology nerds know that these mutations often occur in the womb. In this case, the OCA2 gene, which is also involved in the production of melanin, is disrupted to make the eyes blue rather than brown.
