Hi All, Apr 14, 2009
If most of these dead seals are beheaded, and I understand this to =
be the case, then one can confidently conclude that the mortality is =
from natural or accidental causes; i.e. ice or movement of a ship in ice =
as opposed to the swing of some man held cutting tool.
Seals in water will either be submerged or with the head just above =
the surface. And when thinning ice is breaking up in a high wind one can =
expect collisions between pans. Seals must breath at intervals so they =
must take their chances, pop up between pans and if their timing is =
wrong; kachunk.
On the other hand, the orientation of seals on ice will be much less =
regular (probably about 1/6 would be rotated such that a suitably =
positioned killer could lop off a head, assuming this could be done =
without a chopping block below it) and their lateral position relative =
to the killer would also not be regular (probably about 1/6 of those =
that had some body part within reach of a cutting tool and with suitable =
rotation would be positioned laterally such that the neck could be =
severed).
So roughly 35 out of 36 seals would be oriented and positioned such =
that some body part other than the neck would be more readily struck. =
And consequently one would expect nearly all of the fatal wounds to be =
to the large, exposed and vulnerable areas; rib cage or body spine =
because, when the seal was within striking distance, one or both of =
these large targets would almost always be oriented such that it could =
be hit.
These considerations are based on extensive inexperience with seals =
and sea ice.

i have no offering of a method for the 'headlessness issue' but this =

this second one where the pelts are not utilized and all seems to be for =
naught. literally hundreds of headless seals wash up on the shores of =

assume its fishermen but i'd love to know for sure.=20
