If you're looking for a unique island souvenir to take home with you, consider buying a stuffed lionfish from the gift shop at the Indigenous Eyes Ecological Park and Preserve. The lionfish has a reputation as one of the prettiest fish in the sea, which is in contrast to the destruction it brings to parts of the Caribbean where it is not indigenous. A single lionfish eats as many as eight other fish in a day, wreaking havoc on the native fish populations around the Dominican Republic. They are caught by local fishermen, and then stuffed by workers at the Indigenous Eyes center. You can do your part to help spur eradication efforts by buying one—they cost as little as around $40.
