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.

This incredible image of a larval octopus–which can fit on the tip of your finger–was taken soon after it was collected on a research cruise, preserving its beautiful coloring.

After larval (baby) octopuses hatch from eggs, they float in the currents as zooplankton until they grow large enough to defend themselves. Few will survive to this stage, instead becoming food for larger organisms.
