摘要：

Two widely distributed northern hyperiid amphipods were studied in the Barents, Greenland and Norwegian Seas. The length frequency was analysed in populations from six different regions. The life span of the Atlantic water species Themisto abyssorum was found to be 1 year in the southern part of the investigated area, and 2 years in the northernmost localities. Its body length reached a maximum of 18 mm. The Arctic species Themisto libellula has a life span of 2-3 years and had a maximum body length of 31 mm in the examined material.
