Round 4: 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. A genus of annelids often called “zombie worms” obtain lipids from this substance from whale carcasses. The turkey vulture is the only vertebrate that primarily feeds on this substance. Three of the four species of modern hyenas are named for their ability to “crush” or “crack” this substance. Herbivores like giraffes may chew on this substance to obtain sufficient calcium and phosphate. For 10 points, osteophagy refers to feeding on what hard, mineralized tissue? ■END■
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]
