The biggest I have worked was a female burm. She was part of a snake show I worked with in 1993. She was billed at 25’ and 300 pounds. She was legit about 21’ and 200 pounds. A real monster.
The biggest I have seen in person was at Snakes Alive in Cherokee, NC. That one was another female burm. She was billed at 28’. Not sure the legit measurement. I spoke to the owner last year. That snake died some years back. He told me that they weighted her the day she died at 280 pounds.
The largest I have ever owned was a male burm. He is approximately 17 feet and he weights about 80 pounds.
