Mysisn.

Brit.

/ˈmʌɪsɪs/, U.S.

/ˈmaɪsɪs/

Origin: A borrowing from Latin. Etymon: Latin Mysis.

Etymology: < scientific Latin Mysis (P. A. Latreille Buffon's Hist. Nat.: crustacés et insectes (1802) III. 36), perhaps < Hellenistic Greek μύσις closing of lips or eyes < ancient Greek μύειν to shut the eyes (see mystery n.¹) + -σις -sis suffix.

Zoology.

A genus of malacostracan crustaceans, originally comprising all the opossum shrimps (family Mysidae: see mysid n. and adj.), but now restricted to a smaller number of related marine and freshwater species. Also (usually in form mysis): a crustacean of this genus (also mysis shrimp).

1828 J. V. Thompson Zool. Res. 16 The Mysis, or Opossum Shrimp, a Genus instituted by Latreille, appears to have been hitherto noticed by very few Naturalists.

1842 Penny Cycl. XXIII. 80/2 The second pair of antennæ are inserted below the preceding, as in Mysis.

1870 Amer. Naturalist 4 404 We obtained alive..a Mysis and two species of Gammarus.

1891 Daily News 29 Jan. 5/2 The shrimp-like mysis.

1946 Nature 13 July 71/1 The following arthropods were apparently unaffected: Chironomids, Mysis, Sphæroma and Carcinus.

1971 Oxf. Bk. Invertebr. 132/2 By day, Mysis lives in deep water, rising to the surface at night.

1992 Pract. Fishkeeping Mar. 64/1 Many ‘impossible’ species are specialist feeders so why do some fish keepers still knowingly buy them and hope they will adapt and thrive on mysis shrimp.

attributive. Designating the zoea stage in the life cycle of certain decapods, esp. lobsters and crayfish, in which the larva resembles a crustacean of the genus Mysis. Esp. in Mysis stage.

1902 Proc. Royal Soc. 71 70 The primary system [of chromatophores] appears in the embryo, is completed in the ‘Mysis-stage’, and persists throughout life.

a1933 J. A. Thomson Biol. for Everyman (1934) I. xi. 223 The emerging larva is described as a ‘Mysis’ stage, because it is very like a little old-fashioned crustacean called Mysis.., which is a much less evolved type than the lobster.
