Flagellum

A long, multi-segmented sensory appendage found at the distal ends of the antennae. [Mauchline, 1984]
Antennal endopodite; thin, tapering, multiarticulate, elongate extension of antenna and antennule (distal to peduncle). [Hobbs and Jass, 1988]
Multiarticulate appendage of antennule (2 present) and antenna (1 only); also appendage of exopods of maxillipeds.
(pl. flagella) [Poore, 2004]
Multiarticulate distal portion of antennule, antenna, or exopod.
(pl. flagella) [McLaughlin, 1980]
Multiarticulate, usually whiplike terminal part of the antennule or antenna (Fig. 3B).
(pl. flagella) [Perez Farfante and Kensley, 1997]
Slender, multiarticulate distal part of antennule, antenna or exopod. [Moore and McCormick, 1969]
The distal, multiarticulate endite attached to the antennal and antennular peduncle and exopods of the maxillipeds. [Ingle, 1983]
The long, tapering distal part of either the antennula or antenna, generally made of many annuli. [Wilson, 1989]
The multiarticulate, typically filamentous part of an antennule or antenna. [Hobbs, Hobbs, and Daniel 1977]
The multiarticulate, usually whiplike terminal portion of an antennule or antenna.
(pl. flagella) [Chace and Hobbs, 1969]
The multiarticulate, usually whiplike terminal portion of antenule or antenna.
(pl. flagella) [Butler, T. H.]
The often long and multi-articled region distal to the peduncle of the antennule and antennae, and the basis of the uropod. [Holdich and Jones, 1983]
(Taxon-specific: Order Diplostraca) One of two multisegmented branches of antenna; each of the up to 25 segments (articles) bears a row of spine-like setae anteriorly and brush-like setae posteriorly. Number of segments is of taxonomic importance. [Stachowitsch, 1992]
(Taxon-specific: Class Cephalocarida) Aesthetasc. [Stachowitsch, 1992]
(Taxon-specific: Order Cumacea) Distal division of antennule of antenna (peduncle, flagellum). In antennule, one may distinguish a larger outer (main) and smaller inner (accessory) flagellum. Flagellum of antennule bears aesthetascs. (multiarticulate, uniarticulate). [Stachowitsch, 1992]
(Taxon-specific: Order Tanaidacea) Distal division of antennule or antenna (peduncle, flagellum). Antennule may bear two flagella (with distal segments bearing aesthetascs). [Stachowitsch, 1992]
(Taxon-specific: Order Decapoda) Distal of two divisions (peduncle, flagellum) of antennule or antenna; typically paired in the former, unpaired in the latter. Slender, consisting of numerous segments (articles). May also refer to branch of mouthpart. (straight, bent; filiform, fusiform, plate-like; cross section: circular, dorsoventrally flattened, U-shaped; hairy, smooth, spinose). [Stachowitsch, 1992]
(Taxon-specific: Order Amphipoda) Distal division of antennule or antenna (peduncle, flagellum). May bear sensory structures (aesthetascs on antennules, calceoli on antennules and antennae). If two flagella are present on antennule, one distinguishes a larger (primary) and smaller (accessory) flagellum. [Stachowitsch, 1992]
(Taxon-specific: Order Isopoda) Distal division of antennule or antenna (peduncle, flagellum); composed of a varying number of articles. [Stachowitsch, 1992]
Schematic representation of an isopod illustrating morphological terms. [Kensley and Schotte, 1989]
(Taxon-specific: Order Isopoda) Distal part of antenna or antennule, usually multiarticulate, occasionally reduced to one or a few articles. [Kensley and Schotte, 1989]
(Taxon-specific: Order Isopoda) Narrow distal part of antenna or antennule, usually multiarticulate, occasionally reduced to one or a few articles, without intrinsic musculature. [Wetzer et al. 1997]
(Taxon-specific: Order Mysida) In antennule, pair of elongate branches of peduncle. In antenna, elongate inner branch of peduncle consisting of three- to four-segmented basal section and multisegmented distal section. Also refers to annulate distal part of outer branch (exopod) or thoracopod. [Stachowitsch, 1992]
(Taxon-specific: Order Stomatopoda) Distal section of antennule or antenna (peduncle, flagellum); slender, consisting of numerous segments (articles). Antennule bears three flagella (one dorsal and divided ventral flagella); antenna, one flagellum (on endopod). [Stachowitsch, 1992]
(Taxon-specific: Order Leptostraca) Distal division (peduncle, flagellum) of antennule. Represents inner branch (endopod). May also refer to endopod of antennule. (long with many small articles, small with few large articles). [Stachowitsch, 1992]
(Taxon-specific: Subclass Branchiura) Palp. [Stachowitsch, 1992]
(Taxon-specific: Subclass Copepoda) Multiarticulate distal section of antennule. [Stachowitsch, 1992]
(Taxon-specific: Class Remipedia) Distal section of antennule. One may distinguish a longer dorsal flagellum composed of 11 or 12 segments (articles) and a shorter ventral flagellum composed of 8 articles (in one case fused into a blade-like structure). Each article bears several setae. [Stachowitsch, 1992]
(Taxon-specific: Superorder Syncarida) Distal division of antennule or antenna (peduncle, flagellum). (paired, unpaired) (See also scaphocerite). [Stachowitsch, 1992]
(Taxon-specific: Order Thermosbaenacea) Distal division of antennule or antenna (peduncle, flagellum), paired in the former, unpaired in the latter. (See also aesthetasc). [Stachowitsch, 1992]
(Taxon-specific: Order Euphausiacea) Elongate, multiarticulate distal end of antennule or antenna. Paired in the former, unpaired and representing inner branch (endopod) in the latter. [Stachowitsch, 1992]
