The remaining rays will be placed back into the main exhibit and the zoo is not commenting on weather they will be replenishing the original population of rays.

Rob Laidlaw, executive director of ZooCheck Canada, was quoted by Cnews stating “”We don’t believe animals should be taken from the wild so people can play with them.” Ultimately questioning the educational value of such ray petting exhibits.
