Blubber has been harvested for centuries, yet only recently has it come to light that about half the volume of blubber consists of a complex mesh of collagen fibers wrapped around each animal.
Selama berabad - abad, blubber telah dipanen orang, namun baru belakangan ini diketahui bahwa kira - kira setengah volume blubber terdiri dari anyaman rumit serat kolagen yang membungkus setiap binatang.
