She looks like a goldfish in a bowl, but she’s actually a blackfish in a tank.  A very small tank.  A new video has been posted on YouTube, apparently taken by a drone, showing Lolita, a 22-foot-long killer whale, swimming in furious circles in her diminutive pool at the Miami Seaquarium. For decades, opponents of orca captivity have decried the size of Lolita’s tank. But the overhead perspective of the one-minute video puts her living conditions into stark relief.
