Atergatis roseus, the pancake crab, is a species of reef crab from the family Xanthidae with a natural range extending from the Red Sea to Fiji. It has colonised the eastern Mediterranean by Lessepsian migration through the Suez Canal. The flesh of this crab, like many other species in the family Xanthidae, is toxic.

This colourful round crab can be very commonly seen on many of our shores in coral rubble areas and reefs. Slow moving, it usually hides under large coral rubble pieces, but can be quite active at night.

The primary tool for identification of brachyuran is usually based on classical taxonomy mostly on morphological attributes. The red egg crab, Atergatis integerrimus is sometimes mistaken for stone crabs Menippe rhumpii because of morphological similarity (Vartak et al. 2015).It was, therefore, the objective of this study to provide a complete mitogenome of toxic crab Atergatis …
