| Clark says timber rattlesnakes and other pit vipers may be the most social of all snakes. |
| It's like that fairy tale where vipers and toads jump out of the mouth of the accursed mean little girl when she tries to speak. |
| To enhance this mental picture, boas and the pit vipers have heat-sensitive pits that further confirm the stranger as food or threat. |
| Overseas they have a mixture of cobras, vipers, asps and snake types that we don't have here, that produce quite different effects. |
| While human encounters with cobras, vipers, and pythons can prove fatal, more often than not it is the snakes that are killed. |
| Disturbed that I had been reclining unsuspectingly with vipers, I became snake-paranoid. |
