Racekiela ryderi explained

Racekiela ryderi is a species of freshwater sponge in the family Spongillidae.^[1] It was first described by Edward Potts in 1882.^[2] It was collected on Sable Island in 1899 by John Macoun, a biologist with the Geological Survey of Canada, and given the name Heteromeyenia macouni by A.H. Mackay in 1900.^[3] It was originally assumed to be endemic to Sable Island but is now considered to be the same species as Racekiela ryderi, which is more broadly distributed.^[4]
