Minuca
Minuca is a genus of small, burrowing crabs in the family Ocypodidae. They are commonly known as “ghost crabs” due to their pale coloration and nocturnal habits. Minuca species are found in coastal areas of the Atlantic Ocean, specifically along the Eastern Seaboard of North America and the Caribbean.
Characteristics
Minuca crabs are typically small, with a carapace width of up to 3 centimeters. They have a distinctive, elongated carapace that is wider than it is long. Their color ranges from pale gray to white, and they have long, slender legs that are adapted for running on sand. Like other ghost crabs, they have prominent eyes on stalks that can be retracted into sockets for protection.
Environments
Minuca crabs are found in sandy beaches and coastal areas, often near the high tide mark. They are burrowing animals and spend much of their time in burrows that they dig in the sand. These burrows provide them with shelter from predators and the harsh conditions of the intertidal zone.
Diet
Minuca crabs are omnivorous and feed on a variety of organic matter, including decaying seaweed, algae, and small invertebrates. They are also known to scavenge on dead animals.
Life Cycle
Minuca crabs have a complex life cycle that involves several larval stages. After hatching, the larvae drift in the plankton for several weeks before settling on the seabed. Once they settle, they molt several times as they grow into adults. The lifespan of Minuca crabs is relatively short, typically around 2-3 years.
