A pair of parotoid gland, which locates near the tymphanic membrane is definetely a poison gland, but it is not on frog but toad ;)

See the two big ovoid "bumps" at the caudal part of eyes

Ha! Actually there are some differences between them, some of them are:
- Skin surface, frog's is smoother and moist while toad's is rough (since the presence of tubercles) and dry.
- Body shape, frog's is slimmer than chubby toad.
- Teeth, frog doesn't have teeth in "V" bone while toad doesn't
- Bone shape, frog's is slender than toad's
- The presence of parotoid glands on toad
- Habitat, frog prefers watery place like ponds, rivers, etc. while toad is somewhere drier.
- Frog can swim well, toad cannot.
- Eggs, frog's are scattered, toad's are arranged in string.
- Food preference.

Also, I and 4 friends of mine founded "Herpetology Study Club" in our campus :)

@Tina
Think of how many people you help ! And I know this feeling but as I said be a good doctor and then the possibility of an accident is actually very little.

:oops: Naaah, I am not genius at all. "Mad scientist" could be the appropriate term for me :P When you were me, you would find out that there was nothing you could do except to do all those courses ;)
