Coastal Belize volunteer opportunities

Hello,

Does anyone have recommendations for short term volunteer opportunities in coastal Belize? I am looking to stay in more eco-style accommodations while there and find a project for 1-2 days (marine related?). Of the following areas- Hopkins, Placencia, Punta Gorda, where might I be mostly likely to find what I'm looking for?

Thank you!
