Remembering Thelma and Louise

It has been an uncommonly hard year for us here at the Reptile Zoo. Shortly after the loss of our beloved Twinkie, we found that our dynamic duo, Thelma and Louise had too passed. It seems unfair and tragic that after the loss of such a big part of our team, we must say goodbye to another member that made our little zoo so special. The two-headed Texas ratsnake who delighted kids and adults for the past 14 years has sadly gone on to snake heaven, leaving a two-headed hole in our hearts.

Thelma and Louise was an incredibly special snake. Most polycephalic (that’s science talk for more than one head) creatures are stillborn, and even fewer survive longer than a few days or weeks once born. Our two-headed duo surpassed all odds, surviving to an incredible 14 years. Considering that a normal one-headed Texas ratsnake has a lifespan of 10-15 years we’re ultimately saddened but unsurprised by her passing.

Polycephalic creatures are formed when twin embryos fuse inside the egg or womb they are developing in. Any animal can have two heads, but snakes are one of the few species that can generally survive, or even in special cases like Thelma and Louise, thrive. The ability of a two headed animal to survive generally depends on just how well individual parts and organs formed. Thelma and Louise each had their own throat and windpipe, which joined up to share one stomach and set of lungs. In general, whichever head got to the food first was the one that got to eat. This occasionally led to some funny conundrums, like when Thelma and Louise each had one end of a mouse and wouldn’t let go, leading to a Lady and the Tramp-esqe dinner.

In the end, Thelma managed to wrestle the mouse away from Louise (Louise was the left head) and send it down to their shared stomach. Either way, they were both fed!

Showing off their pearly whites...

Rest in Peace lovely girls, you’ll be sorely missed.

Good day! I know this is kind of off topic but I was wondering which blog platform are you using for this website? I'm getting sick and tired of Wordpress because I've had problems with hackers and I'm looking at alternatives for another platform. I would be fantastic if you could point me in the direction of a good platform.
