“Redouan Bsharyis best known for studying cleaner wrasse—tiny underwater hygienists that pick parasites from much larger fish, like the roving coral grouper. In 2006, Bshary decided to follow one of the groupers to see whether it sought the services of several cleaners in a row. Instead, he saw something wholly unexpected. The groupers repeatedly swam up to giant moray eels and made a vigorous head-shaking signal. It was a call to arms—a signal that meant “Hunt with me”.
The eels respond by swimming off with the groupers. They can slink through crevices and flush out hidden prey, while the groupers are lethal in open water. When they hunt together, little fish have nowhere to flee.”

California Whales Rebound in a Big Way
“The number of California blue whales has returned to near historical levels. The species had been hunted nearly to extinction, researchers say.
“The recovery of California blue whales from whaling demonstrates the ability of blue whale populations to rebuild under careful management and conservation measures,” says Cole Monnahan, a doctoral student in quantitative ecology and resource management at University of Washington and lead author of a new study published in the journal Marine Mammal Science.”
“Space is a dangerous place. That message resonated again on Monday, when theRussian Federal Space Agency— Roscosmos — announced that a team of experimental geckos tasked with copulating while in orbit did not survive their journey.
