Naturally, of course the mighty kraken are r-strategists, producing large numbers of planktonic offspring with each mating. Female kraken eventually mature and grow to a size large enough to menace commercial ship traffic, while males remain near-microscopic and serve only to breed during their brief lives.
Unusually, the krakens produce only one kind of offspring at various stages of their life. While below 6 inches or so in size, young tiny krakens will produce only male offspring, while between 6 inches and 600 yards they will produce only female offspring, The reason for this adaptation is not currently well-understood, especially given the relative rarity of larger kraken specimens even in the era before they were hunted on an industrial scale.
