Uca jocelynae
Physical Features：
Uca jocelynae is a new species of crab that was only announced in recent years. It looks similar to the Northern Calling Fiddler Crab (Uca borealis) and was previously mistaken for a different colored Northern Calling Fiddler Crab. It is now listed as the 11th species of fiddler crab in Taiwan with bright yellow or orange major chelipeds. The main difference is that there is an obvious light blue area on the lower half of the shield and two deep depressions on the immovable finger connected to the major chelipeds. The major chelipeds of the immovable finger on male crabs point to the distal triangular teeth.
Living Habits：
It mainly inhabits muddy land above the low tide line, or sedimentary mudflats between reefs or pebbles beside rocks.
