Big Bertha was first identified in 1992. She was not named “Little Bertha” at that time, which let us to believe that she always been a large female. We estimate her wingspan at 12-14 feet.
Big Bertha is a regular guest at the manta ray experience and is comfortable with close encounters to divers and snorkelers. She frequents Manta Heaven and Manta Village. She is a favorite manta seen by many guests and her size leaves most speechless.
We have seen Big Big Bertha pregnant several times. Her belly bulges out and in the last few months being close to term, her back will fill out as well.
DESCRIPTION OF MARKINGS
Big Bertha’s identifying markings have a definite trident as her main spot pattern. It includes the spear like sharp tips. In addition, she also has “ The Hawaiian Island Chain” going up her left side. Lastly she has three dots off by themselves up to her right that seem to make a triangle.
