Captivating Facts About Nepenthes Rajah, Earth's Biggest Carnivorous Plant
Carnivorous plants are predatory flowering plants. They trap and consume small mammals, reptile,and insects to get vital nutrients from their bodies. They attract their “victims” with ingenious methods such as colorful leaves, sticky hairs, attractive scents, and sweet nectar.
The main features that define carnivorous plants include having an attraction device, a trap mechanism, and multiple methods of digestion and absorption.
Charles Darwin laid the foundation of modern research on carnivorous plants. In “Insectivorous plants” (1875) he provided the first detailed descriptions of plants that entrap insects. These plants can dissolve animal protein using enzymes.
Joseph Dalton Hooker, botanist, and explorer, when first noticed pitcher plants in 1859, described them as “one of the most striking vegetable productions hither-to discovered.”

Nepenthes Rajah, Earth's Largest Carnivorous Plant
Borneo’s Nepenthes Rajah is the largest carnivorous plant in the world. It is also famous as “the king of pitcher plants.” It’s a trap containing up to 3 liters of water and two and a half liters of other digestive fluids. Moreover, they can seduce insects, frogs, and other small-sized mammals with their juicy looking flesh and sweet nectar. After trapping them, it digests their prey with acids.
Although ants are the favorite meal of the Nepenthes Rajah, it can also trap much larger organisms in its urn-shaped cavity. For example, rats, lizards, or even birds. N. Rajah and one other pitcher plant, the Nepenthes Rafflesiana are the only plants that can catch mammals as prey. Also, Nepenthes Rajah is a very sturdy plant, with a shrew-shaped orifice and a non-slippery rim. This unique feature allows the victim to stick around and feed longer.
In 2011, a team of scientists led by carnivorous plant expert Dr. Charles Clarke published their discoveries after studying interactions between tree shrews, rats, and Nepenthes Rajah. But, their main observation clearly can be cataloged as awkward. The report’s main finding was that these small mammals often rests on the rim of the plant. Moreover, they feed on nectar from the lid while defecating into the urn. The distance from the front side to the nectar of the plant corresponds to the length of the three shrew’s body dimension. This unusual structure allows it to feed and defecate simultaneously.
This exchange is not a bad thing for N. Rajah. The rat and three shrew manure provide the plant with valuable nitrogen and other nutrients. Thus, they are crucial for their growth and development.
