How are the platypus’s bill and feet specially adapted for survival in their environment? (Site 2)
lapo4ka [179]
Platypus is an Australian mammal that lives in deciduous forests. Platypus's bill is adapted in order to allow platypus to travell and find its way in the river without using vision. This adaptation is achieved through special receptors that sense touch and electricity. Platypus's feet are webbed, enabling them to swim fast and efficiently and move easily on muddy surfaces.
