How big?
He's the longest, but you be the judge.
I'm not the smallest dude, fairly muscular and athletic to boot but I'm no NBA sized fella either.
When people need to see some type of reference for size, quarters, cellphones and dollar bills don't always cut it.
I'm not much for posting pictures of myself on the web, but I have a couple modified pictures with 2 different snakes here.
The first is the retic, Wallace. He's my longest snake and I'm guessing he's 7.5 to 8.5 feet in length. If you think a male SD x Dwarf x Mainland retic at 8 feet is big you may feel differently after seeing this.
If you follow the boa constrictor forum, you've seen these. Sniper, my 6 year old male BC. He's MAYBE 7 feet long. Possibly under, or doubtfully just over.
The density of a BC at a shorter length makes the boa seem huge IMO. They are so strong too.
That said, the boa is a much better handling animal.
Wallace often becomes annoying in a short time and handling becomes unrelating.
