Platypuses are shy, semi-aquatic mammals native to eastern Australia, and unlike many animals they are seldom recorded vocalising, which is why a genuine clip stands out online. Their calls are usually described as low growls, purrs and chattering sounds made during social or defensive moments, rather than the cartoon quacks people often expect. As short animal sounds have become popular for edits, reactions and classroom clips, this recording is mainly used as a curiosity piece, giving creators an authentic noise to match an animal most viewers have only seen in pictures.
