Do you really know the difference?
This is a common question that kids always want to know the answer to. Honestly, the answer is very easy. There are two main differences. Insects have three body parts: Head, thorax and an abdomen where as Arachnids have two main body parts: Head, and a cephalothorax (combined thorax and abdomen). There is one more very distinctive differential characteristic.

Anybody?
The legs, that's right. Insects have six legs and arachnids have only eight. Well, both insects and arachnids can either be toxic, poisonous or even venomous for snakes of course. Did you know that some insects like blister beetles, aka Bombideer beetles, are able to physiologically sequester toxins from certain plants and use these toxins as defense mechanisms. Pretty cool, huh. Well, tune in to the next post for more insect-arachnid fun facts.
