Recognition of poisonous spider (toxicity level)
Spiders are the largest class of arachnids and rank seventh in total species diversity among all living organisms. There are potentially hundreds (maybe thousands) of spider species anywhere in the world. While many are harmless to human, some are very poisonous. It would be nice to tell if a spider is poisonous (or extremely poisonous) by an image or an instantly taken photo.
