A horseshoe crab marked as (2) had obvious mating scars if female, had some epibionts, and while it still showed a lustrous carapace, it was starting to show wear and tear, the mottling was not as apparent and the eyes were also not quite as clear as a one. In order to be marked as (3), the horseshoe crab had to look much more worn, with larger numbers of epibionts, and a worn shell that lost its lustrous qualities and no longer had any…

The second phase, which differs from most land vertebrates, is the development of a “shelf of bone” above the shaft of the rib bone to form the unique T-shape. The final phase is the development of its teardrop-like shape, which is caused by the widening of the lower ridge of the ribs, which also reinforces the rib. History has shown that the third phase is unique only to the…

    I learned more about the tortoise and iguanas living on the Galapagos Islands from this exhibit. I thinks it’s really cool the marine iguanas on the Galapagos islands have evolved to excrete salt through their nasal cavity. By excreting salt, these iguanas are able to be herbivores eating algae while diving underwater. Another cool fact is that the male marine iguana can dive up to 30ft and can spend close to an hour underwater. I learned more about the difference in carapaces between tortoises…
