Sub-adult basking on a partly-submerged log next to the water. Several crocodilian species have been shown to exhibit "metachrosis", whereby skin colour can gradually change over a period of time. Basking alligators can appear almost black during basking, which would be beneficial in terms of their ability to absorb both heat and UV rays. Water is also important for temperature regulation in crocodilians, acting as a buffer to extreme temperatures.
