Uca arcuata
Name:
Bowed Fiddler Crab
Physical Features:
Bowed fiddler crabs are common in muddy places near river outlets in Taiwan. For their dark geometrical back patterns, they are also called “net-patterned” fiddler crabs. The males have tiny orange-red dots on their claws, while the females are characterized by pure red claws. Baby crabs have rather different colors. Some are orange-red and others light blue.
Living Habits:
Bowed fiddler crabs like to pile up soil around their caves. This makes their homes look like tiny volcanoes which range from 1 to 8 cm tall. The crabs mainly live under mangrove trees and the muddy area beside a river. They love loamy soil.
