TUESDAY AMPHIBIAN LARVAE part ii

The past week hasn't added much length to my amphibian larvae. The Barred Tiger Salamanders (Ambystoma mavortium)have increased by about half a centimeter, the Woodhouse's Toads (Bufo woodhousii) have shown no visible increase, although their morphological change has been striking (above). The front legs, virtually invisible last week, are well developed, and the hind legs continue to grow. The body has taken on a new spotted pattern and the head shape is altogether more toad-like, with protrusions at the eye and jawline developing. I can perceive no morphological change in the salamanders over the past week (below).
