Adult male platypuses largely avoid each other, outside of this mating rivalry. [6] Platypus venom is likely retained from its distant non-monotreme ancestors, being the last living example of what was once a common characteristic among mammals. [2] Fossil records show that venom delivery systems were not sexually dimorphic in ancestral ...
Venoms have adapted to serve a wide variety of purposes. Their intended effects can range from mild fleeting discomfort to paralysis and death, and they may be highly selective in which species they target, often making them harmless to all but a few specific organisms; what may be fatal to one species may be totally insignificant to another ...
