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

Etymology: < scientific Latin Megalops (1803 in sense 1: B. G. E. de la V. de Lacépède Hist. nat. des poissons V. 289) < megalo- megalo- comb. form + -ops -ops comb. form. With sense 1 compare French mégalope (1809), and with sense 2 compare earlier megalopa n.

Zoology.

1. Now in form Megalops. A genus of marine fishes including the Indo-Pacific or ox-eye tarpon, Megalops cyprinoides, and the Atlantic tarpon, M. atlanticus (family Megalopidae).

1834 E. Griffith et al. Cuvier's Animal Kingdom X. 443 Elops, L., have all the characters of megalops, but want the elongated filament of the dorsal.

1840 E. Blyth et al. Cuvier's Animal Kingdom 321 Megalops, fins and jaws generally formed like those of the Herring, but the belly not trenchant, nor the body compressed.

1880 A. Günther Introd. Study of Fishes 661 Megalops.—Body oblong, compressed, abdomen flat. Scales large, adherent; lateral line distinct.

1961 E. S. Herald Living Fishes of World 72/2 In the other genus in the elopid family—that of the tarpons, Megalops—the last ray of the dorsal is extended as a long filament.

2. A free-swimming larval stage in the developments of crabs, following the zoea stage and having the adult number of trunk segments and legs, and large eyes; a crab in this stage. Also called megalopa.These larvae were at first mistakenly thought to represent a distinct genus, named Megalopa by W. E. Leach (see quot. 1815 at megalopa n.).

1855 W. S. Dallas in Syst. Nat. Hist. I. 312 In this form the young animals have received the name of Megalops.

1896 J. W. Kirkaldy & E. C. Pollard tr. J. E. V. Boas Text Bk. Zool. 226 There is no mysis-stage, but the young one passes through a prawn-stage (the so-called megalops).

1974 Nature 4 Jan. 30/2 Crabs, mostly still in the megalops stage.

1976 W. W. Warner Beautiful Swimmers v. 106 A larva metamorphoses rather radically into something known as a megalops.

1985 Sci. Amer. May 77/3 The megalops has eyes on stalks (as the adult crab does), three pairs of walking legs and crude claws.
