Two rare blue cray-fish found in the Boston area have been named.
The two white crays were found in a Boston park in March, but it wasn’t until now that they were named, officials said Monday.
The crayFISH program, which provides samples to state and local fish and wildlife officials for identification, identified them as the small crayFish and the big crays.
Both species are white crickets, and they have an adult length of less than four inches and weigh between two and five pounds, officials with the state Department of Fish and Wildlife said.
The white crayers, which have a yellow or orange body, are native to North America, but the big ones are not, officials added.
They are also found in North America’s Northeast and Midwest, according to the department.
The small crays are smaller, weighing less than three to five ounces.
