How do Tungara frogs manage moisture? They prevent their eggs from drowning by encasing them in a thin layer of protein/carbohydrate foam, creating floating bubble nests.
Paper wasp manage moisture by creating nests made of cellulose—chewed up wood—and saliva. When mixed with cellulose, protein contained in wasp saliva creates a waterproof covering.
Moisture is attracted and trapped on a tick’s mouth thanks to as crystalline substance that attracts atmospheric moisture and accumulates on the mouth, attracting water using crystallized osmolytes.
Venomous snakes release different venoms with different functions. Some breakdown blood by releasing venom containing enzymes that degrade blood proteins, breaking apart clots.
Studying leech saliva could help replace toxic stain removers. Leech saliva contains enzymes that inhibit blood from coagulating, making the blood thinner and allowing it to flow freely.
Vampire bats digest and degrade blood thanks to a compound in their saliva call draculin, which prevents blood from forming insoluble strands of fibrin proteins.
One packaging prototype modeled the curvature and unique combination of shapes of a tortoise shell, which includes hexagons, irregular five-sided pentagons, and four-sided plates, creating a dome with flexibility in its composition.
Poppy flowers unique packaging includes two think thick outer sepals that protect immature buds. The sepals split open and detach after the crepe-paper petals unfurl, deploying seeds within minutes.
Beetle wings are protected by a tough outer elytra "packaging," which is made of a flexible material called resilin that is concentrated in a gradient along the folding patterns of the wing.
