The whale was spotted making the epic 12,000-mile trek from Alaska to Mexico and back without its tail-fin, an incredibly important body part for the animal.
Most whales travel at a speed of 4 mph, but this tailless whale seemed to be going around 3 mph.

It is still a miracle that the whale is swimming nonetheless.
Whale watchers have said the whale seems to be a little underweight, but not by that much.
The whale likely lost its tail in commercial fishing gear.
