Crocodile fern is a tropical species of plant that is part of the Polypodiaceae family. It belongs to the Microsorum genus, which consists of approximately 50 species found across the world. Crocodile Fern’s scientific name is Microsorum musifolium. Like many other ferns, this plant is epiphytic in nature. This means that Crocodile fern has the ability to grow attached to trees or even in between rock cracks. The plant will absorb all nutrients and water it needs through the air, rain, or tree.
