An animal that feeds on this substance relies on endosymbiosis with Oceanospirillales bacteria. Cattle feeding on this substance (-5[1])is often an early indicator of a bovine botulism outbreak. (-5[1])The Epicyon and Borophagus genera of Miocene–Pliocene canines developed several adaptations for feeding on this substance. (-5[2])A genus (10[1]-5[1])of annelids often (10[1])called “zombie worms” (10[2]-5[3])obtain lipids from this substance (-5[1])from whale (10[1])carcasses. (10[2])The (-5[1])turkey vulture is the only (10[1])vertebrate (10[2])that primarily (10[1])feeds (10[1])on (10[1])this (-5[1])substance. (10[4]-5[7])Three (-5[1])of the four (10[2]-5[2])species (10[1])of modern hyenas are named for their ability to “crush” (10[2])or (10[2])“crack” (10[3])this substance. (10[4])Herbivores (10[2])like giraffes (10[2])may chew on this substance to obtain sufficient calcium and phosphate. (10[3])For 10 points, osteophagy refers to (10[1])feeding (10[1])on (10[1])what (10[1])hard, mineralized tissue? (10[9])■END■
