What I was told was that the whale live stranded and thrashed on the =
beach before dying which may have caused some of the abrasions. Why it =
was so far up the Bay is another question. =20
The injuries are not particularly what encounters with vessels would =
cause. Props cut deeply into the skin and blubber for example and are =
regularly spaced. With broken bones from collisions such as the jaw, =
there are often no outward indications other than some bruising which =
often is not visible on darkly pigmented whales.
Entanglement will have linear scars and abrasion but to fully assess =
from the photos of the carcass it would be helpful to have photos of the =
whale when it was still alive on the beach. Most entanglement scars are =
on areas of the whale where rope can catch: flipppers, tail stock, =
head/mouth.
Don McAlpine from the New Brunswick Museum will be looking at the baleen =
that was salvaged to perhaps assess whether it is a fin or sei. He has =
seen many sei whales during his time at an Icelandic whaling station and =
none were are dark as this whale and most were also smaller. The skin =
pigmentation also does not readily agree with the fin whales that I have =
seen but variations can occur. Genetic analysis may be required to =
confirm species id.

Has anyone suggested that this whale looks as if it had an bad =
encounter with a motorboat? That is what it looks like to me, though I =
am no expert.
Will the authority on cetacean forensics please step forward!
