beach grass stalks, leaves and seeds, and insect adults and larvae. Their predators include domestic cats (which were extirpated from the island some time in the late 1800s), short-eared owls, and northern harriers. The IUCN has classified the beach vole as vulnerable. Endangered species of pirate spiders, piping plovers, roseate terns and arctic terns can also be found on the island. Access Muskeget is inaccessible to most boats because of shoals and sandbars. Kayaking there can be very dangerous because of rip currents, swells, and whirlpools. Specialized boats designed to navigate the difficult waters around the Island depart from Nantucket Harbor. Muskeget Island Airport, a small privately owned turf landing strip on the island, is accessible to STOL aircraft, but has been designated by the FAA as being for emergency use only.
