What is this bottle found in the ocean in Belize

My husband found this bottle in the ocean while digging through sand near the shore in Belize. After cleaning it up, there are three shells that are too big to remove. The top won't come off, the critters had to have grown in the bottle. (There is a small opening in the cap.) I'm wondering how we can identify the origin of the bottle.  It's about 4.25 inches tall with a diameter just under 2 inches.
