I've always found that the way a ram's horns curl is really quite fascinating. They curve in such a deliberate way so as to almost create a helmet. They look like something almost modeled or handcrafted, yet this is how they naturally grow, to protect and help this bighorn sheep win over mates, and having seen a couple of males literally butt heads, it's quite a fierce display of strength. Who is stronger, who can withstand the constant pounding of heads.
