Some shallow-water hydroids (Cnidaria: Hydrozoa) from the central east coast of Florida, USA Author Calder, Dale R. text Zootaxa 2013 2013-05-14 3648 1 1 72 http://dx.doi.org/10.11646/zootaxa.3648.1.1 journal article 10.11646/zootaxa.3648.1.1 1175-5326 5264362 22089255-436A-4DBB-BD93-1D3C8CF281FE Plumularia floridana Nutting, 1900 Fig. 10d Plumularia floridana Nutting, 1900: 59 , pl. 2, figs. 4–5.— Jones, 2002: 217 . Type locality. USA : Florida , “two miles west of Cape Romano...” ( Nutting 1990: 59) . Voucher material. Off Vero Beach, 27°41.2’N , 80°14.5’W , 17 m , 13.ii.1974 , small biological dredge, R/ V Gosnold Station 220/226, four colony fragments, up to 1.9 cm high, without gonophores, ROMIZ B1080 . Remarks . Material examined here came from a station on the inner continental shelf off Vero Beach. With the exception of its occurrence on floating Sargassum ( Fraser 1944 ) , Plumularia floridana Nutting, 1900 is a species more frequently recorded inshore than offshore along the southeastern United States . While common in estuaries of South Carolina ( Calder & Hester 1978 ; Calder 1983 ), it has not yet been reported from hard bottom areas on the shelf between North Carolina and Florida ( Cain 1972 ; Wenner et al . 1984 ). As noted earlier ( Calder 1997 ), the species is eurytopic, surviving temperatures down to 10° C and salinities as low as 25‰. An extensive synonymy of this species is listed in Ansín Agís et al . (2001) , who described material from the Canary Islands. Reported distribution. Atlantic coast of Florida . Biscayne Bay ( Jones 2002 ). Western Atlantic. South Carolina ( Calder 1983 ) to Brazil (Oliveira et al . submitted), including Bermuda ( Calder 1997 ) and the Gulf of Mexico ( Calder & Cairns 2009 ). It extends northwards to New England on Sargassum ( Fraser 1944 ) . Elsewhere. Believed to be circumglobal, mostly in tropical and warm-temperate waters ( Ansín Agís et al . 2001 ).
