Elektriska ålar jagar i flock
Undvik vattenförekomster, som Amazonas floder ”eller badkar”. Elektriska ålar är farliga. Carlos David de Santana, en zoolog, upptäckte att elektriska ålar kan delta i samordnade flockattacker mot sitt byte. BBC News:
”It was really amazing – we thought these were solitary animals,” said researcher Carlos David de Santana. […]
Douglas Bastos, from the National Centre for Amazonian research in Manaus, Brazil, filmed the behaviour – capturing the moment of the collective electric strike. Small fish, called tetras, are the target of the attack; they fly into the air and land stunned and motionless on the water.
