A.
Killer whales are listed as endangered species in some regions but not on a global level. This is because they travel in such tight-knit families, which means their ability to thrive and survive is directly related to where they live.
B.
Killer whales travel in pods that are matriarchal in nature and even more close-knit than human families. Female killer whales begin producing offspring at the age of fifteen but mate outside of their own families to avoid domestic squabbles.
C.
Killer whales are extremely social mammals that use sophisticated verbal hunting techniques. Using clicks, whistles, and pulse calls, killer whales hunt approximately thirty species of fish and consume, on average, five hundred pounds of food each day.
D.
The killer whale is one of thirty-five dolphin species. Killer whales are like other whales, but they are actually even more like dolphins. The way they communicate with one another is a lot like dolphins, too. Both animals use sound and body language to communicate.
