OK but please understand that the laws that were on the books under there Netherlands Antillies may not be the same for country Sint. Maarten. I don't know about shells but taking or killing conch is illegal on both sides of the island so I'm curious where these shells are coming from. 15 years ago, there were hardly any conch to be seen snorkeling or diving and since they have been protected there are lot's most and doing very well. Taking shells, dead or alive from the Natural Reserve which Orient bay is part of, is prohibited. You can find whole conch shells that have died naturally in the water off of La Samanna and as far as I know there is no problem taking those but be careful, something living inside may die and make an awful stench in your suitcase!
