I concur. Bigguy is right here. This list is a mess and the department need to redo it. I think it's important that they do so asap, otherwise new keepers will unknowingly produce hybrids. Someone should write to the department to let them know.
The problem with this though is that different distinct species shouldn't be able to produce offspring that can then go on and produce more offspring. A bredli can mate with a diamond and produce fertile offspring.
