Chiming Beavers

Sri Raji Attenbaugh and his expedition were making their way through the jungle of Kateen, at dawn, wherein, they hoped, laid the secret to the Gods' unfortunate condition.

"What's that, Sri?"
"Oh, those are beavers, nothing to see here, just a family of beavers."
"Oh no!"
"What, Sanksrit, what is so terrible about tree-eating beavers?"
"These are not regular beavers, sir, hear the song!"
"The song?" Raji paused his own speech, even relaxed his breathing, and soon heard the musical metallic chimes, like five pairs of tiny cymbals striking up and down to an unknown melody underwater, and yet one could hear them clearly, unlike underwater, but with the added, deeper notes that only could be made in that environment.
"The song of the beavers, Sri, no one knows whence it comes, but they are always accompanied with it. The song is always underwater, so the beaver we see is not the one making the song..."
The enormous rodent, quite possibly a 20kg specimen, unconcerned, kept eating at the spare-limbed sponge tree, until it fell, and dragged it back underwater. The song got louder, when it did, but dimmed again when its mate, a lither female, decided to eat some of the stub before retiring. as Sanskrit had said, the song changed while two beavers were underwater, and returned to normal with only one visible, then subsided when they were both gone.

Basic Information

Anatomy

With four stout, sharp-clawed paws, a flat, solid tail and a close-set head with long, ever-growing teeth, a beaver is well equipped to swim, cut down trees with its teeth and fight.

Additional Information

Perception and Sensory Capabilities

These beavers are odd sorts, so much that many believe they're not wholly natural creatures:

Most comfortable underwater, but not eating any underwater plants, instead going out of the water to cut trees

Very keen of hearing, but it's more remarkable underwater, where the sound carries from further away

When out of the water but near it, they announce their presence with this as-yet unexplained chime, it fades when more than two meters away from the water
