What to know about Who are the secret gardeners of a parasitic plant?

A study by Kobe University botanist Kenji Suetsugu identifies land hermit crabs as both external and internal seed dispersers for the parasitic plant Balanophora fungosa. The research demonstrates that crabs are attracted to the scent of mature plants and transport seeds via their bodies or digestive tracts.

What happened

Phys reports: Who are the secret gardeners of a parasitic plant?.

Why it matters

Sadie Harley Scientific Editor Robert Egan Senior Editor In the coastal forests of a tropical Japanese island near Okinawa grows an inconspicuous plant that is easy to mistake for a mushroom.

Common ground

It is a non-green parasite that feeds on the roots of other plants and produces up to 1 million tiny seeds, each covered in a minuscule, dry fruit.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
