Regarding the possible large size of the squid species. In 1994 whilst on board the 40 foot yacht 'Respite' I encountered a bioluminscent object during the early hours 40 miles off the Portuguese coast near Nazare that dwarfed the yacht. I estimated the body (Mantle?) to be between 80 to 150 feet long and 20 to 45 feet in diameter. The trailing area (beyond the truncated end) appeared to have wriggling pink tubes (Tetacles?) with dark blotches. It was a dark cloud covered night appart from the glow of the yachts navigation lights. The object was visible due to a red bioluminescent diamond 'coarse fishing net mesh' and a brighter glow near the 'head and tentacle' end. I now (many years later) recognise that its shape and movement had the characteristics of the squid family but on a grand scale. From this experience I can now believe that a type of squid 200 feet long could exist. Regarding whale scars would they grow at a uniform rate and remain circular as the whale matures or would they distort?
