Magnificent, rare worm with its own campaign song: the giant Gippsland earthworm

The Gippsland earthworm produces only one amber-coloured egg cocoon each year, which emerges about 12 months later as a 20cm-long big baby. Composite: Guardian Design/Alamy

The giant Gippsland earthworm already has an upbeat campaign song.

“I am a real worm, I am an actual worm,” bangs the chorus of Doctor Worm, a late-90s novelty hit by the American indie rock band They Might Be Giants.
