A team of researchers through a latest study has found that pitcher plant that eats bat poop has a unique way to attract their meal. The pitcher shape of the plant stands out against bat’s echolocation cries, the study found.

The pitcher plant Nepenthes hemsleyana grows mostly in the peat forests of Borneo. The plant is a common place to stay for Kerivoula hardwickii bat species.

Researchers in previously conducted studies have found that the bats and the pitcher plants have a mutually beneficial relationship. The plants provide bats with a comfortable place to stay and rest along with a few parasites and an ideal microclimate.

Bats, on the other hand, provide the plant with its poop. Bat guano is rich in nitrogen, which is an essential plant nutrient.

Co-author Michael Schöner of Ernst-Moritz-Arndt-University of Greifswald in Germany said the new study clearly explains how N. hemsleyana can survive, knowing that its other closest plant relatives captures nearly seven times as many insects than it does.

Schöner told Live Science that one-third of the nuitrogen, which is consumed by the picture plants, comes from the bat species.

Researchers said another species of picture plant found in Borneo called Nepenthes lowii relies on shrew poop for the same purpose.

Researchers said once the bats find the plants, they settle at the top keeping them away from the plants’ deadly digestive liquids, and enjoy a cool place to roost. The findings of the study were detailed on Thursday in the journal Current Biology.
