HETEROPHRYXUS APPENDICULATUS G. O. SARS, 1885 (ISOPODA, DAJIDAE): EXTENSION OF ITS KNOWN RANGE IN THE NORTHEAST PACIFIC AND CARIBBEAN SEA (MEXICO) THAT INDICATES INTER-OCEAN ZOOGEOGRAPHIC DISTRIBUTION

摘要

Heterophryxus appendiculatus G. O. Sars, 1885 (Dajidae) infests at least four species of euphausiids. Since_ 1885 it has been reported from only seven locations worldwide. One free-swimming female specimen was discovered in Zooplankton samples from the northeast Pacific Ocean and three more from the Caribbean Sea of Mexico. In the context of all previous geographical reports and Zoogeographie distribution patterns of their euphausiid hosts, we suggest that H. appendiculatus has a wide Zoogeographie distribution in the tropical-temperate belt worldwide.
