Wow - Thanks for the heads up Matt
Your right - way too skinny.
And IIRC Whale Sharks aren't skinny sharks. I believe a 20 ft long Whale Shark should weigh at least 2-3 tons, not 1 ton -which is what it looks like it would weight - by my guessimation -based on these photos.
People want to see big healthy, and well feed Whale Sharks - not skinny, sickly looking Whale Sharks. They really need give these sharks more shrimp, & krill. Even if that means feeding each whale shark at least 500 lbs of shrimp, krill, and small fish per day.
