This is a drawing of an arrow worm species Pterosagitta draco (Krohn, 1853), which is cosmopolitan, occurring in warm-temperate seas round the globe. It is from phylum Chaetognatha, which are exclusively marine planktonic predators. They all have long curved chitinous hooks projecting from each side of the head, and these are seizing prey along with multiple rows of teeth! In 1993 Austrian researcher Dr. Sigrid Lutchinger wrote a memoir about the New Zealand species published in the New Zealand Oceanographic Institute (now NIWA) Biodiversity Memoir series.
