Water Monitor Lizard at SBWR

Many times when I heard somebody shouting "Crocodile" in Sungei Buloh Wetland Reserve, very high chance is a water monitor lizard. From a distance they did looks like crocodile. Like with other reptiles, monitor lizards are cold blooded, which means they don't maintain their body temperature instead follow the environment.

Cold blooded also often refer to lacking feeling or emotion. Do monitor lizards really lack of feeling & emotion? Monitor lizards feed on anything that they can find and swallow including other monitor lizards!After seeing this monitor lizard keep the juvenile close to them at all time, they aren't really 'cold blooded' isn't it?
Judging from the size, the lizard on the left should be the father (male lizard are larger in size) and the mother on the right. What a happy family!

Monitor lizards use their fork-tongue to smells the air to look for food.
I am not sure if the monitor lizards also use their tongue to communicate as seen on this photo.
