I named my island Neuroglia. Reason being, the analogy fits. The animals remind me of neurons (because they are the active communicators) and the island itself (which supplies resources and supports the animals) reminds me of glial cells...hence Neuroglia. I also think it's a pretty name lol (.....I'm currently pursuing a pHd in Neuroscience, so this stuff is always on my mind )
If "Plan A" didn't work, the alphabet has 25 more letters.
