| You may recall Trimorphodon from the photo I posted here (almost exactly 1 year ago!) and the BioGSC calendar this past year. Again, a fairly aggressive snake, but also very beautiful. This year, I discover that it’s had a name change (T. biscutatus to T. quadrupex). |  |
| A new snake species for me, I had misidentified this juvenile Senticolis (formally Elaphe) triaspis as Trimorphodon quadrupex (now distinct from biscutatus) (Savage and Bolanos 2009 Zootaxa), but the reddish color and round pupils didn’t sit well with me. When I keyed the snake out, I discovered that the juvenile is very different than the adult. Although it’s a very pretty, young constrictor, it’s fairly aggressive and has bitten several times – luckily, I didn’t misidentify a poisonous snake… |  |

With the photographs I took of the snake, I discovered some anomalies on its head – Ticks! It’s a bit difficult to see here, but there are two ticks, buried deep behind its head. I’ve removed them, but the snake was completely ungrateful. |
Much more active than their adult counterparts, juvenile Ctenosaura seem to occupy the same habitat here as some of the Ameiva (maybe leptophys). Additionally, given that juvenile iguanas are more insectivorous than adults, they share some of the same food sources.
