Matuta
Matuta is a genus of crabs in the family Matutidae. These crabs are commonly known as “sand crabs” or “ghost crabs” due to their pale coloration and their ability to burrow quickly into the sand. They are found in shallow waters along the coastlines of the Indo-Pacific region.
Characteristics
Matuta crabs are characterized by their broad, flattened carapace, which is typically covered in fine hairs. They have long, slender legs that are adapted for walking and burrowing. Their claws are also long and powerful, and they use them for defense and capturing prey. The eyes of Matuta crabs are located on stalks and can be retracted into sockets when the crab is burrowing.
Environment
Matuta crabs are primarily found in sandy environments along coastlines. They are often found in shallow waters, but they can also be found in deeper waters. They are active at night, when they come out to forage for food. During the day, they bury themselves in the sand to avoid predators.
Diet
Matuta crabs are omnivorous and feed on a variety of organisms, including algae, mollusks, worms, and crustaceans. They are also known to scavenge on dead animals.
Reproduction
Matuta crabs reproduce sexually. The females lay eggs that are attached to their abdominal appendages. The eggs hatch into larvae, which drift in the water for several weeks before they settle on the bottom and develop into juvenile crabs.
Species
There are several species of Matuta crabs, including:
- Matuta lunaris
- Matuta victor
- Matuta planipes
- Matuta banksii
