oh, yeah; it’s an olm: take a gander
Homer’s Old Man of the Sea
hail the pale protean deity
terrific three-toed, two-toed salamander!
The olm was used by Charles Darwin in his famous On the Origin of Species as an example for the reduction of structures through disuse:
Far from feeling surprise that some of the cave-animals should be very anomalous…as is the case with blind Proteus with reference to the reptiles of Europe, I am only surprised that more wrecks of ancient life have not been preserved, owing to the less severe competition to which the scanty inhabitants of these dark abodes will have been exposed.
Why, it even looks spry on a tie!
