Diagnosis: 24-33 pairs of slime pores in front of the gill openings, 51-70 between the gill openings and the anus, and 10-13 posterior to the anus, giving a total count of 88-102 slime pores. Total cusp count of teeth 32-36 (Fig. B). Usually six pairs of internal gill pouches. Size: in the eastern Atlantic lengths were reported to be between 600 and 790 mm. Anatomical details are given by Marinelli & Strenger (1956), and systematical information is given by Fernholm (1981).

Habitat: littoral to meso-abyssal (20-600 m) on muddy bottom. In Norwegian fjords reported to occur to 1,100 m. Food: see family. Reproduction: eggs are few in number (19-30) and large (20-25 mm), the horny shell has a cluster of anchor-tipped filaments at each end (Fig. C).

Distribution: Mediterranean Sea around African coast (Dieuzeide, 1956), absent in eastern Mediterranean and Black Seas; Atlantic coast from Portugal to the North Sea, Skagerrak, Kattegat and Varanger Fjord; from Davis Strait to Florida (unpublished). Abundant in many areas.

Eggs, larvae and young stages. No larval stages in M. glutinosa; eggs few but large (circa 20 mm) (Schnakenbeck, 1931:1, fig. I | Walvig, 1963, in Brodal & Fange: 546-556, fig. 10-14).
