Round 10: Tossup 7

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

ANSWER: bone [accept bone marrow; accept skeletons or skeletal remains; prompt on lipids until read by asking “from what substance?”; prompt on corpses or carcasses or answers referring to dead animals; prompt on whales or whale falls until “whale” is read]
