Sundews are a type of carnivorous plant. Their leaves are covered with long, nectar-tipped tentacles that attract prey. But the nectar isn’t just enticing — it’s also a powerfully sticky “glue” that traps insects. Once an insect is trapped, the nearest leaf curls inwards and begins to secrete digestive enzymes that dissolve the insect, allowing the plant to absorb the liquified nutrients left behind.
