Each year, 20,000 dolphins are slaughtered in Japan, and the Taiji hunt alone is responsible for killing hundreds of animals. The few who survive the blood-red waters are sold into captivity, fated to spend the rest of their lives cut off from family and performing at zoos and marine parks. Most of them, like this one, are butchered and sold for their meat.
The juveniles, too young to butcher or sell into captivity, are often thrown back into the ocean. Their deaths aren't counted in the official death toll, but it's unlikely that they can survive after their entire family has been killed.
While proponents of the hunt market the massacre as a Japanese tradition, drives hunts have only become commonplace in the last few decades. The Taiji hunt in particular is driven by a handful of local men who are getting rich off the killing.
