Physophoran.

Inflections: Plural Physophorae, unchanged.

Forms: 1800s Physsophora, 1800s– Physophora.

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

Etymology: < scientific Latin Physophora, genus name ( P. Forsskål Descriptiones animalium(1775) 119; the altered form Physsophora is attributed to Oken 1815) < physo- physo- comb. form + -phora , neuter plural of -phorus -phore comb. form. Compare French Physophores , plural noun (1808). In sense 2, probably after scientific Latin Physophorae, subfamily name ( J. F. Brandt Prodromus descriptionis animalium(1835) 32 ).

Zoology.

1. A genus of pelagic siphonophores, characterized by a long hydrosome, a relatively small pneumatophore, and several nectocalyces; an animal of this genus.

ΚΠ

1834 H. McMurtrie tr. G. Cuvier Animal Kingdom (abridged ed.) 483 In..Physsophora.., between the superior bladder and the tentacula are other bladders placed side by side.

1868 tr. L. Figuier Ocean World viii. 231 The Physophora now resembles a flower posed upon a tuft of roots.

1896 J. W. Kirkaldy & E. C. Pollard tr. J. E. V. Boas Text Bk. Zool. 108 As examples may be mentioned: Physophora and its allies.., with long hydrosoma, terminating in a small pneumatophore, [etc.].

1983 Philos. Trans. (Royal Soc.) B. 301 176 Bigelow (1911) explained the apparent anomaly between the situation in Physophora and that in the rhodaliids by suggesting that Physophora..was unlikely to be the direct ancestor of the rhodaliids.

†2. A member of a division of pelagic hydrozoans including various genera of siphonophore. Obsolete.
