OK, really interesting; nice bit of skin on the mantle of the illustrated specimen, but there still appears to be a lot of skin abrasion that is consistent with having been through a trawl (and having been discarded).
Can anyone tell me if any new fishery (or established fishery) operating ~ 250-600 metres occurs off this coast, and what the local bathymetry is off this area?
We've now had five caught here over the past few months (winter-spawning population). If these are females (they have to be, the one ~ 40 feet in length) then they are FULLY mature (and likely spent). If these are true strandings (as in stranding post portem, natural mortality) then this female must be spent. Does anyone have any contact details/persons so that we can get to the bottom of the autopsy?
Money on it that the regularity in periodicity of capture is related to the breeding cycle of the animal in the general vicinity (rather than global warming ... I doubt this to be the case).
Cheers (great post)
