Elasmobranch reproduction and embryology. It's just a topic that has always been interesting. Sharks, rays, and skates are all rather closely related. But we have skates- which lay eggs (oviparity); rays- which give live birth, via internal egg incubation (ovoviviparity); and sharks- which, depending on the species, lay eggs, incubate the eggs, or experience a more "mammalian" pregnancy known as vivparity. And then, there is the intrauterine cannibalism that is known in the species Carcharias taurus, where the fetal sharks are still developing, the yolk sacs have been depleted, so the fetal sharks eat the others within the uterus, resulting in the birth of two offspring (sharks have two uteri, so one from each).

And then there is the parthenogenesis phenomenon, that we only know about because of captivity. Certain sharks- notably bamboo sharks- if absent of a mate, can trigger a response that causes ova to mature and develop into a clone of the mother. This is also known to happen in lizards.

And a large number of female elasmobranchs can also store the sperm of males after copulation to fertilize their eggs for years.

It's just a fascinating topic all around.

I know it's from DtK, but I don't recall the exact bit. Moon landing communications with Houston?

Tastes of human, sir. Would you like a white wine?

I lived in Hawai'i for three years and remember blue stop signs, but not green. Green road signs in Hawai'i would fail to stand out for 3/4 of the year and defeat their purpose.

It could possibly be a stop sign from Ko Olina on O'ahu, but I never spent enough time there to actually absorb the color of their road signs.

Crickets actually aren't bad on their own. We did a "Fear Factor" themed fundraiser for Katrina relief back in high school. We made cricket sugar cookies, cricket-covered chocolate strawberries, flavored mealworms, things like that. Things weren't selling as well as we would have wanted, so, being the weird kid with an extra bag of crickets, I stated that I would eat a live cricket for every $20 that was pledged. That ended up raising an old extra $140, and I ate 7 crickets in front of my classmates. They were relatively tasteless, and, since I found that it didn't gross me out, years later, when I was an educator at our local aquarium, I would use, "Wanna see me eat a live bug?" strategically to bribe my summer camp kids into staying calm. If they were well behaved for an hour after lunch, I would pop one of the feeder crickets into my mouth. It brought much joy and disgust to the 10 year olds.
