Great stuff, Frank
I have always been interested in the learning ability of animals (as well as humans). I agree that turtles are able to learn complex tasks and evidently along with the monitors are the smartest reptiles. I have seen some limited studies on determining the learning ability of amphibians. Newts are able to distinguish color and patterns to ensure mating with the proper mate of the same species. Salamanders have a remarkable sense of navigation and able to find their home pool even when relocated 2 or 3 miles away. As far as frogs go, most learning tests have failed.
Andreas Elepfandt writes, in part: "
Xenopus shows good learning abilities for wave and sound stimuli, and to some degree for visual and chemical stimuli. It is the only frog so far in which long-term memory and complex learning have been shown. Thus
Xenopus is capable of learning rules in its environment. The form of acquisition of the learning tasks by
Xenopus conforms to that known from other vertebrates." Elepfandt has written several articles on
Xenopus sensory perception and underwater acoustics and hearing. From
The Biology of Xenopus (1996)
I have been keeping
Xenopus for many years. I enjoy watching them and recording their calls. I have identified at least 3 distinct calls: one male and two female.
Keep up the great work, I really enjoy your blog.
