We've already seen floating fish finders that transmit readings from out on the water, plus we've also seen waterproof quadcopters ... so perhaps it shouldn't be surprising that someone has combined the two. The AguaDrone can first tell you where the fish are, and then fly your lure to that spot. Learn more: - http://www.scoop.it/t/21st-century-innovative-technologies-and-developments/?tag=Drones

Scoop.it!
By Megan Gannon, LiveScience News Editor: A male fish from Mexico has some fearsome genitalia.
Females of this species have evolved to have a big ball of tissue that blocks most of the genital pore. This means the female would have to deliberately allow the male to mate with her unless the male evolved a counter-response, Langerhans explained. The four-hooked genitalia could help the males overcome resistance and latch onto a female's genital pore and deposit sperm inside her. (Fertilization in the Gambusia genus takes place inside the female's body and she gives birth to live young.)
