The spitting cobra has evolved to aim the venom that it spits into or as close as possible to the antagonist’s face and eyes. [1] The cobras can measure and adjust the venom dosage being delivered, based on the size and relative distance of their target, in order to ensure the highest envenomation potential possible.

Some moths do not feed after emerging from the pupa, and have greatly reduced, vestigial mouthparts or none at all. All but a few adult Lepidoptera lack mandibles (the superfamily known as the mandibulate moths have fully developed mandibles as adults), but also have the remaining mouthparts in the form of an elongated sucking tube, the proboscis.

For this reason, blindness in animals is a unique topic of study. In general, nocturnal or subterranean animals have less interest in the visual world, and depend on other sensory ...
