The 'Snake Leaf' Fern (also known as Pyrrosia serpens) is a distinctive fern species known for its unique, elongated, and narrow leaves that resemble the shape and texture of snake scales, giving the plant its common name. Native to tropical and subtropical regions of Asia, this fern is an epiphytic fern, often found growing on rocks, tree trunks, drawing moisture from the air. However, when cultivated in gardens or as a houseplant, it is typically grown in well-draining, slightly acidic soil that retains moisture.

Snake Leaf fern prefers warm, humid conditions and is tolerant of low to moderate light. It can grow in both shaded garden areas and as an indoor houseplant in indirect light. It is relatively low maintenance, requiring regular watering to keep the soil moist, and it appreciates higher humidity levels, which makes it suitable for bathrooms or terrariums. 

Snake Leaf Fern (Pyrrosia serpens) is generally considered pet friendly. It is non-toxic to both cats and dogs, making it a safe choice for households with pets. However, as with any plant, it's always a good idea to discourage pets from chewing on plants, as ingesting any kind of plant material can potentially cause gastrointestinal upset, even if the plant itself is non-toxic.
