A conservation group in St. Maarten says a local Internet marketplace has illegally offered endangered sea turtle hatchlings.

The Nature Foundation nonprofit says a "growing number of wild animals" are being advertised on local online sites.

The group says it managed to intervene in the sea turtle sales over the weekend before the protected creatures were harmed. It wasn't immediately clear if police made any arrests.

The conservation group distributed screenshots of what appear to be three leatherback hatchlings being offered for sale online.

Raccoons have been advertised locally in recent days.

Group manager Tadzio Bervoets says it closely monitors the Internet marketplaces for illegal wildlife sales.
