Common crop pesticides kill honeybee larvae in the hive

"We found that four of the pesticides most commonly found in beehives kill bee larvae," said Jim Frazier, professor of entomology, Penn State. "We also found that the negative effects of these pesticides are sometimes greater when the pesticides occur in combinations within the hive. Since pesticide safety is judged almost entirely on adult honeybee sensitivity to individual pesticides and also does not consider mixtures of pesticides, the risk assessment process that the Environmental Protection Agency uses should be changed."

Baby Slipper Lobster

This baby slipper lobster, found during a Census of Marine Life expedition, is completely transparent, though as the creature grows, a thick shell will cover it.

The lobster’s bizarre eyes may confuse predators while it floats among plankton, or tiny animals, according to the new National Geographic Society book Citizens of the Sea: Wondrous Creatures From the Census of Marine Life.

Bioluminescent Barbeled Dragonfish!

This beauty (a.k.a. Idiacanthus) lives about a mile deep underwater. They have weirdly stalked eyes as baby larvae (A) and the stalks somehow disappear as they mature (B). Almost nothing is known about their reproductive habits (how, when and where), but you can see that they dine on jellyfish (look inside B’s throat). Idiacanthus live in all the oceans of the world. These gorgeous pictures were taken by Dr. Christina Wahl and appear in her book, Morphometrics.
