The chemical is also used for observing photosynthetic activities or respiratory indicators (turns green then yellow as CO2 is added).

Snake's Description : Generally Taipans are uniformly olive or dark brown, the head is somewhat darker brown. Snake's Toxic Rank 1 : Inland Taipan is the world's most venomous land snake. Its bite is synonymous with death. Maximum survival time recorded after Taipan's bite is not more than few hours.
Two of the most poisonous snakes are also the most sacred -- the rattlesnake and the cobra. Of all the species of cobra, the King Cobra reigns as the largest venomous snake in the world. When the cobra is alert, it rises up and flattens its neck into the distinctive 'hood' that is instantly recognizable.
