With a wingspan that can reach nearly three meters, the Spotted Eagle Ray is one of the larger ray species in our waters. It is easily recognized by its dark background adorned with numerous white spots and a completely white belly. These rays have a long, pointed tail equipped with several venomous spines. Among other things, these rays eat bivalves and search for them in sandy bottoms. They dig into the sand and sometimes wave it away with their "wings." They also eat crabs, hermit crabs, and snails such as the queen conch. Spotted eagle rays are very social and often swim in small groups.
Yellow Cowries are sea snails found in most tropical seas. In the past, various cowry species played significant roles in trade and culture. Cowrie shells were historically used as currency, particularly in China, Africa, New Guinea, and Indonesia. The ships of the United East India Company (In Dutch, VOC) traded in cowry shells, particularly the “money cowry” shells that represented monetary value, and used them as a means of payment, including for the purchase of enslaved individuals. Today, they are primarily valued as collectibles and used in jewelry. Snails have highly specific diets that vary among species. Some are carnivorous, some herbivorous, and others omnivorous. They have a unique feeding structure called a “radula” in their mouth, which functions like teeth, grazing surfaces and cutting food.
Through the middle of Simpson Bay Lagoon runs the border between the Dutch and French parts of St. Maarten. Since 2014, part of the lagoon has been an internationally protected area. This protection is important because the seagrass beds in the lagoon are vulnerable. Sint Maarten's international airport, the Princess Juliana International Airport, is located near Simpson Bay. Sailing yachts and other vessels regularly seek shelter in the lagoon as storms and hurricanes move through the Caribbean.
