Drymarchon means "Forest Ruler". I'll give rep points to anyone who can tell me what cribo means.........
As far as temperment goes, it depends on the snake. I breed black tails (including unis - which are really a blacktail), erebennus, easterns and yellowtails. I have animals that are aggressive and I have some that are downright placid. Most calm down once in hand but there are exceptions to that rule.
They need a lot of room as adults and care must be taken to not overheat them (I keep my ambients in the low 70s). They eat a lot and they poop alot. I clean indigo and cribo enclosures multiple times a week. While not technically hard to keep, there are some husbandry quirks that they require.
Once or twice a year, I do a speaking gig on drymarchon. I probably still have the powerpoint on my computer somewhere. If I can find it, I'll email it to you.
Do that please Skip. I'm interested in the species but I want to get everything as far as information goes. I'll send you a PM with my email.
