Spider Seduction Requires UV Light
Sex-specific use of UV light to seek out a mate is a first

The female jumping spider attracts mates by using organs called palps, which are located just below her eyes and fluoresce when excited by UV light Without UV wavelengths, these spiders get no love.

Males reflect UV light off scales on their faces and bodies during the mating game, whereas females have sensory organs called palps, typically used to capture prey, that fluoresce bright green when excited by UV light.

In the absence of UV light, the success rate for consummating courtships decreases, explains senior author Daiqin Li of the National University of Singapore. "The fluorescence really seems absolutely essential for the males to recognize the females," comments Thomas Cronin, at the University of Maryland, Baltimore County. "In most other creatures, fluorescence is a supplementary signal to add contrast. In these spiders, it seems necessary for the male spider to find a female."

One week after being born, six baby skunks were abandoned by their mother. Luckily, we had just weaned five kittens off of our resident farm cat a day before and hoped that perhaps she might take them on as her own. She was reluctant at first, but she let them nurse - a positive sign. Two weeks have gone by and the six little "Stinkers" are thriving and their new mom couldn't be happier. She has become quite devoted to them and even carries them around to show them off to visitors

Mozart the Iguana

[Since this is a family blog, you will have to use your imagination as to Mozart's red, swollen, um, problem]

Mozart, an iguana with an erection that has lasted for over a week, will have his penis amputated in the next couple of days.

Veterinarians at Antwerp's Aquatopia had sought to treat the animal's problem, but decided removal was the only solution because of the risk of infection. The good news for Mozart and his mates is that male iguanas have two penises.

Mozart, sitting on the shoulders of his keeper as camera crews focused on his red, swollen erection, seemed unperturbed by the news.

"It doesn't bother him. He doesn't know what amputation means," said vet Luc Lambrecht, adding that Mozart's sexual activity should be undimmed by the operation.
