Researchers have observed butterflies in the Amazon swarming the heads of turtles to drink their tears.
The reasons for the butterflies’ seemingly strange behavior is to attain the precious salts found in the turtles’ tears and eye balls.
Sodium is so precious in the rainforest because it is over 1,000 miles from the Atlantic Ocean, a major source of salt in the region.
Turtles secrete excess sodium through their tears, and the butterflies are somehow able to detect this surplus of sodium, latch on to what must seem to them a gigantic, terrifying creature, and lap up their sweet,or rather salty cry juice.
