    ..5 cm and 11 cm). During the spitting act the cobras performed fast undulating head movements that lead to a larger distribution of their venom. This behavior increases the probability that at least one eye of the aggressor is hit...

    Zoology (Jena) 108:195-200. 2005
    ..Although this low sensitivity may be sufficient for the detection of fish-generated water motions, it makes it unlikely that L. curtus has a special hydrodynamic sense...

    J Comp Physiol A Neuroethol Sens Neural Behav Physiol 195:753-7. 2009
    ..Our results show that the spray pattern of spitting cobras is not fixed. Instead the snake matches its venom distribution to the size of the target independent of target distance...
