Scientists discover electric eels hunting in a group

Deep in the Brazilian Amazon River basin, scientists discovered a small, river-fed lake filled with more than 100 adult electric eels. Researchers witnessed the electric eels working together to herd small fish into tightly packed balls. Groups of up to 10 eels periodically split off to form cooperative hunting parties. Those smaller groups then surrounded the prey and launched simultaneous electric attacks. The findings overturn the idea that these serpentine fish are exclusively solitary predators.

Penned release of green geckos has potential to help preserve threatened native species

Researchers outlined how they translocated 19 barking geckos to Mana Island, using the method of penned release – enclosing them in a 100m² pen for three months so they get used to the site and hopefully establish a breeding population.

Research reveals how teeth functioned and evolved in giant mega-sharks

(University of Bristol) A pioneering study by University of Bristol researchers finds that the evolution of teeth in the giant prehistoric shark Megalodon and its relatives was a by-product of becoming huge, rather than an adaptation to new feeding habits.
