Things like threshers (Alopiidae) are possibly as light or lighter by length, because of their elongated tails, but a tiger shark or great white is several times the weight of a crocodile of the same length. E.g. a 13 foot Great White could weigh 2000 pounds or so, a crocodile that heavy would likely be approaching 18 feet long. 20 feet long is extremely big for a great white, being about the upper range of its size, and I believe a fish that size would weigh 4000 pounds or more, although from the little reading I've done there seem to be so few records of great whites that big it's hard to tell for sure.Anyhow, adjusting the sizes of the Large and Huge sharks a bit like I did for the Crocs is probably what I'd do. We could call them a Medium / Big / Large shark, and then have a "Giant Shark" for the Huge variety.Those seem too high. A 500 pound shark is probably only around 10-12 feet long, A run of the mill great white (2000-2500 pound?) is ~13-15 feet. I'd probably compress the SRD stats to make the Medium shark a "Big Medium" and the SRD Huge shark "Very Large" and possibly tweak the Hit Dice a bit, something like:Big Shark (200lb, 6-8') - 3HD, Str 13Large Shark (500lb, 10-12') - 5HD, Str 17Very Large Shark (1500lb, 14-16') - 7HD, Str 21Huge Shark (4000lb, 20-24') - 10HD, Str 25They could also do with having a better Con than the SRD gives them - it's significantly behind the standard advancement rate, and I have read a good many anecdotes about some sharks being hard to kill.A 35 foot long lamniform shark (presumably a Carcharodon/Carcharocles megadon) should weigh something of the order of 32,000 pounds - that's more Gargantuan than Huge!I don't think there's any reason to think C. megalodon was "much chunkier" than a great white. There is little fossil evidence apart from teeth and jaws, so there's little solid proof of what form the body takes. Great whites have very robust builds for lamniform sharks, so there's a fair likelihood that megalodon had a somewhat slimmer, more average body, shape than Carcharodon carcharias - although being much bigger it obviously would be heavier.The 70 foot length estimate sounds a bit optimistic to me (let along the 100 foot+ claims that are floating about). 50 feet is probably a more reliable guess for a megalodon's length.</blockquote>
