Quote from Shei DayeAwhile back Bill Crawford turned in a beautiful fish to the IUSA for a record which looked like a giant mangrove at 29 pounds. In that case, it had the tooth patch of a mangrove, but it had the scale count of a cubera, and it had the lower teeth of a mangrove, but it had the upper fangs of a cubera. (By the way, the hook and line record for a mangrove is 17 pounds.) It was very weird, so in the end, the IUSA relied on tissue samples that were sent to a lab. It was determined that that particular fish was a hybrid. I guess in rare cases they can cross breed. The IGFA (for hook and line records) has also received a few hybrids over the years.
