Polar bear milk can contain as much as 40% fat at the start of lactation, making it one of the richest milk sources among land mammals. This extraordinary nutritional density is a crucial survival mechanism for bear cubs, powering their rapid growth and helping them build essential fat reserves for life in demanding environments.

Hooves are a specialized anatomical adaptation found in ungulates, a diverse group of mammals, which play a foundational role in their survival. The remarkable benefits of hooves include providing crucial protection for sensitive foot structures and enabling powerful, efficient locomotion across varied terrains.

Research on captive grizzly bears shows they naturally self-regulate their diet to obtain a protein content of roughly 17-22% to maximize body mass gain. The answer to how much protein do bears have is complex, depending on the species and seasonal shifts in their omnivorous diet.
