• First record of a tanaidacean crustacean fed upon by an arrow worm (Chaetognatha)

抄録

This paper reports the first observation of a tanaidacean crustacean in the gut of a chaetognath. The female tanaidacean was identified as Pseudotanais sp. in Pseudotanaidae and the arrow worm was a member of Sagittidae. The chaetognath was collected with a small plankton net attached inside a larger beam trawl. The net included bottom sediments, and female pseudotanaids are generally benthic whereas chaetognaths are planktonic, this case of predation thus may have been the result of cod-end feeding in the net.
