You run into certain limits on biology, however, that block such things as some of the description of the kraken.

Didn't you know, the Loch Ness Monster has apparently died of old age (this is what the tourist board are claiming since there have been no sightings in something like 4 years now).

Personally, I think a squid got him.

As far as sea monsters are concerned, I'm not sure, there are almost certainly no Island-sized turtles out there (Can you imagine one coming ashore to lay eggs?) but I wouldn't be surprised to find there are bigger yet Squids and Octopi out there waiting to be found.

Ya, like those new kind of deep sea sharks that were discovered a few years ago, the ones that are larger than anything else known to man.

[Flipside]

I could be thinking of the wrong thing, but weren't those fossils of prehistoric ones?

[Grey Wolf]

They were. The largest known living fish are the whale sharks. Anyway, the fossils were still smaller than the blue whale, which is normally considered to be the largest any sea-dwelling animal can get.
