Arrow worms primarily feed on small planktonic organisms such as copepods, krill, and other tiny invertebrates. They are active predators, using their well-developed grasping spines to capture their prey. Some species are also known to feed on fish eggs and larvae.

98% of animals have vertibrates. the only ones that wouldn't are things like worms, clams, and animals that live on the sea floor of the twilight zone.
Arrow worms are important in marine ecosystems as they are voracious predators of small planktonic organisms, helping to regulate their populations. They also serve as a food source for larger predators, contributing to the transfer of energy up the food chain. Additionally, arrow worms play a role in nutrient cycling by recycling organic matter in the water column.
