This fish may or may not be dead, but getting to that size being albino or some other form of albinism, Most of the bill fish are the size of you thumb nail when they are fry, the go from that size to a 30lb fish in less than a year. Billfish have a rapid growth rate, even a large one say 110lbs would only be a 5 or 6 year old fish. As for surviving the billfish dont have too many preds after they reach a certian size, and they are also faster than most other fish.
