It’s a new week here at Tree Limin’ Extreme, and therefore we have a new Critter of the Week. This week we are gonna take a look at some of the Virgin Islands crabs.

Hermit Crabs are a group of crab species found all over the world. There are about 1100 hermit crab species. Most live in marine environments, but the ones most commonly encountered here in the Virgin Islands are of the land loving variety. Hermit are related to other crabs, but they differ in that they carry around their home on their backs. Their abdomen does not have the hard shell of the rest of their body, and so it is vulnerable to injury and predators. They remedy this by finding the discarded shells of other sea creatures (most often sea snails), and crawling inside. Hermit crabs can be found all over the Virgin Islands, although always near to the water, which they need to reproduce. The are also mostly nocturnal.

Ghost crabs, or sand crabs, are common along our beautiful white sand beaches. Called ghost crabs because of their pale color and nocturnal nature, they are mostly seen quickly scurrying down the sand. They are responsible for the holes found dug in the moist areas of the beach. The crab uses these burrows to escape the hottest part of the day, and to spend the cooler winters in some areas. They come out at night to feed on clams, and other smaller crabs. They are also a natural predator of sea turtle hatchlings. You can try to catch them if you see one, but they sure are fast!

Several species of so called “land crabs” are also native in the Virgin Islands. Also called pond crabs, in the British Virgin Islands, they can grow quite large and are a popular food source here. They are the main ingredient in the popular dish called “Crab and Rice.” They can most often be found near muddy holes along the edges of mangrove swamps, salt ponds, or other perpetually damp areas. The crabs mainly live on land, having organs that get oxygen from the air rather than the water, but these crabs still live and feed near the water. Keep a lookout for these large crabs, and be sure to try some crab and rice if you can, it is a rare treat!

Critter of the Week: Mongoose

We have a new critter of the week! This week we are taking a look at the mongoose:

A Mongoose

Mongooses (yes, the proper plural is mongooses) are a group of small weasel like mammals, originally from Asia. Here in the West Indies, including the Virgin Islands, the species of mongoose is called the Small Indian Mongoose. Native to India, Afghanistan, and Pakistan, the mongoose was introduced to the Virgin Islands in the 1800’s. They were brought here due to their fierce predatory habits, and it was hoped that they would help to eliminate destructive rats on the sugar plantations. It is an often repeated fact here in the Virgin Islands that the tree rats are nocturnal, while mongooses hunt during the day. Mongooses also do not climb trees, so they wer not effective in controlling tree rat populations. The mongooses adapted well, though, and they are now quite common. They can be seen especially easily in the national park on St. John, and at Magens Bay on St. Thomas.

Despite the success of the species, they are still considered a destructive pest. They have no natural predators in the West Indies, and as such their population has exploded. They are especially adept at hunting snakes and lizards, and within the Caribbean, they have been responsible for no less than 7 extinctions. While dangerous to snakes, they pose virtually no threat to humans. They are quite curious though, and will often follow hikers down the trail for a bit.

Even with it’s status as a pest here, the mongoose is still a big part of local pop culture. You can find many things named after them including shopping centers, and even an anti-litter campaign mascot. The mongoose has become a classic part of Virgin Islands culture.

Come visit our islands to see a mongoose, and for a chance to see one while zipping through the trees give us a call here at Tree Limin’ Extreme at 340-777-9477, or visit our website at www.ziplinestthomas.com.
