Smilisca baudinii tadpoles

Smilisca baudinii (eaten here and a froglet here) is one of two hylid tadpoles that are being reared (Hyla microcephala is the other).  The tadpoles are medium-sized, with a broad tail and they are somewhat light in color, especially compared to the bufonids.  The mouth is similar to that of the other tadpole species here in that it has 2/3 denticles (with the second anterior denticle medially broken) and a prominent beak; however, the large, complete oral disk is completely surrounded by many rows of papillae; some of the other tadpoles have gaps in the papillae surrounding the oral disk.  Additionally, the toe pads are visible on the budding feet of the tadpoles, which is a good indicator that this is a hylid.

Senticolis triaspis

Colubridae - Senticolis (Elaphe) triaspis - 06.26.2010 - 08.23.23

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… Colubridae - Senticolis (Elaphe) triaspis - 06.26.2010 - 08.21.00

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.

Snake predation

In Palo Verde, a student noticed this Leptophis mexicanus preying on a tree frog (I think it’s Smilisca baudinii).  This is the second time I was able to observe a Leptophis attack a frog, although this occasion was quite different, given that the snake had captured the frog by the hind legs; the frog made distress calls and the snake had some difficulty dragging and controling its prey.

Additionally, I’ve been feeding frozen rats to the two corn snakes I’ve recently inherited.  Below is 1 (that’s its name) gulping down a rat.
