['thul]

Generally, "many" is to 'thul's experience not more than four. It is counted "one, two, many" so it is 3+, or sometimes 4 or more.

Of course, some common dragons are two-legged, with two arms and two wings, others have two legs and two wings, and the last of the most common varieties is the one with four legs and two wings.

There are a few rare ones without wings or with no legs, but they're rare. Some of those have wings and arms (but not legs).
The spiders (that exist outside fantasy) that you should really fear are not the big ones like tarantulas, as they are generally mostly harmless... its the small ones. Black widow spiders are fairly small, yet deadly.

Same can be said for scorpions. Big Claws = safe, small claws = dangerous. The big-clawed ones need such claws to hold prey while venom spreads. Small-clawed ones have such strong venom that they do not really need claws to hold prey at all.
