Onychophorans, also known as velvet worms, are soft-bodied, segmented invertebrates found in moist, tropical environments. They belong to the phylum Onychophora and are characterized by their velvety texture and numerous legs, which are not true jointed appendages. These creatures are primarily nocturnal and are known for their unique method of hunting, using slime to capture prey. These fascinating animals are closely related to both arthropods and annelids, sharing features with both groups. Onychophorans play a significant role in their ecosystems as predators of small invertebrates. Their evolutionary history dates back over 500 million years, making them important for understanding the development of terrestrial life.
