I would like to announce that while some journals chose to pass on my manuscript (though not without some positive reception and strong recommendation by some of the reviewers), I will be imminently releasing my manuscript as a preprint within the next week or so.

Okay, my preprint is finally out. It's a review on not just the size variation for the killer whale, but also two large beaked whales and the sperm whale.

https://www.biorxiv.org/content/10.1101/2024.09.05.610699v1

In my deep search of the literature, I've found that the largest verified weight for a killer whale was a piecemeal weighing of 9,950 kg taken from an 8.6 m male from the Antarctic that I mentioned years earlier. This was indeed among the literature published by Sleptsov,1965 (I had to visit a reference library to find this source). I've also ran statistical analyses on the weight relationships between resident killer whales, transients, and the Icelandic herring-feeding population and found that there was a statistically significant difference in the weight relationships, with the transients being notably heavier than the residents. The weight formula for transients is more similar to Type A killer whales in this regard. If the Soviet weight relationship for predominantly mammal-eating (likely Type A) killer whales from the Southern Hemisphere is used, the maximum size for a mammal-eating male (9.5 m from Nishiwaki and Handa, 1958), would weight 13.6 metric tons. In my review, there's some more info on growth parameters for killer whales and a lot of info on the beaked and sperm whales.

Making sure you two see this in case you're interested.

Here is an interesting take on the possible different species of orca.

Strong candidate for the size record - 7.6 to 9.1 m and 16000 pounds specimen called Old Tom is a solitary adult Northwest Atlantic killer whale. He has been sighted off the coast of northern New England and iEastern Canada, https://killerwhales.fandom.com/wiki/Old_Thom
