I spent a lot of hours snorkeling before Wilma and had explored most of the coastline from the Allegro all the way to Hotel Cozumel over a few trips, and I'd say those shallow reefs were totally trashed, but the areas I'm referring to were shore dives or snorkeling sites. The further south you go from Paradise the less effect Wilma had, but it did damage Paradise & some of the shallow DIVE SITE reefs but it didn't trash them. Anyone who spent much time shore snorkeling prior to Wilma knows what I'm talking about, but because we didn't have digital underwater cameras very few have proof of what it used to look like. Pre Wilma the coral grew right along the shoreline in many areas, and because of that marine life was everywhere whether as fish, fans, or rays etc.
