Interesting! Some don't fit in any of the categories, some of those are animals, some are bands names and some are actually both!
Let's start by saying that Spain and France aren't animals or bands names. They are European countries.
Eagles, The Turtles, The Beatles could be considered both. The Turtles, The Beatles in this case, are probably referring to the band due to the use of 'The'.
Camels, Penguins, Gorillas and Beluga sturgeon are definitely animals and not bands.
The Animals, Arctic Monkeys, Gorillaz, Crazy Horse, Lamb Of God are names of bands and they aren't animals.
