Quiz WriterJoselyn

Joselyn wasn’t too keen on multiple choice in high school. She vividly remembers the first biology exam she passed by only the skin of her teeth, which dragged her overall average down into the embarrassingly low 90s (she doesn’t want to talk about it). After swearing off any high school or university courses that required multiple choice tests, Joselyn managed to get an English degree by sweet-talking her professors into offering only essay-style exams. Needless to say, this did not exactly endear her to her peers. This rocky start smoothed out in time, though, and after tumbling down a black quiz hole one day while putting off job hunting, Joselyn realized her hatred of all things a-b-or-c had faded and she actually enjoyed dreaming up new ideas for questions and dangerously correct-sounding answers. You won’t find her quizzes an easy ride, but Joselyn just wants to make sure you’re really testing your knowledge.

Did you know?

The poison dart frog is small and less than an inch in adult length, and some may grow to two inches in length.

Their weight is up to an ounce. Most of these frogs are brightly colored with patterns that are associated with their toxicity and level of alkaloids. Poison dart frogs lay eggs in moist places like leaves and plants as well as exposed roots. Poison dart frogs secrete lipophilic alkaloid toxins through their skin. This serves as a chemical defense against their predators and can be active alongside potential predators throughout their day. The most toxic species of this poison dart frog is the Phyllobates terribilis. Predators may even have the ability to withstand the poison when they eat the frog, lie the Leimadophis epinephelus. When chemicals are extracted from the phantasmal poison frog, it may prove to be of medicinal value. Scientists went as far as to make a painkiller, but it was later dropped. Skin toxicity evolved with bright coloration. It depends on the shift of their diet. The captive bred poison dart frogs don't have near as many alkaloids as their kin in the wild. Captive bred poison dart frogs hold their ability to increase alkaloids when they are provided an alkaloid contained diet. These frogs are handled with great care and studied on their lifespan and how they live. It is said that poison dart frogs when living in captivity, can live up to 25 years. They thrive the most because the humidity is 80-100% and the temperature is 72 degrees Fahrenheit during the day and 60 degrees Fahrenheit at night. Poison dart frogs eat ants, millipedes, and centipedes. You can easily spot them with their bright colors or blues, reds, yellows, and black.
