Glenn B. writes an interesting post about newts and salamanders. His two newts remind me of a Lovecraftian critter which HPL never officially named but which for convenience sake is now referred to as a Deep One.
The Deep One was said to be immortal unless killed, and couldn't even starve to death, merely shrinking smaller and smaller but never dying, and regrowing to normal size when they get to eat again.
Not that that's related to anything except that it's what I was reminded of. Anyway, very interesting post by Glenn B., who shows a photo of his two newts and tells about them. Check it out.
