- Velella velella (Linnaeus, 1758) Fig. 1c Medusa velella Linnaeus, 1758: 660. Velella mutica.—L. Agassiz, 1862: 366.—A. Agassiz, 1865: 217.— Fewkes, 1886: 974. Velella velella.— Bayer, 1963: 454, figs. 5–7. Type locality. Mediterranean Sea (Schuchert 2010). Voucher material. Beach north of Jupiter Inlet, 26°56’45”N, 80°04’16”W, stranded on shore, 20.ii.1991, collected manually, one young colony, left-sailing form, 5 mm long x 2 mm wide, without gonophores, coll. D.R. Calder, ROMIZ B1113. Remarks. Strandings of the pleustonic hydrozoan Velella velella (Linnaeus, 1758) on beaches of south Florida vary from one year to another (Bayer 1963). Bayer noted that strong easterly winds during winter tend to blow this species and the related Porpita porpita (Linnaeus, 1758) ashore from the Florida Current just off the coast. The specimen from the beach at Jupiter Inlet examined here was a left-sailing form, as defined by Edwards (1966). Of more than 2500 specimens from the Tortugas studied by A. Agassiz (1883), all were likewise of the “left-handed” (left-sailing) form, with the sail extending from NW to SE along the longitudinal axis of the float. Distributions of left and right-sailing forms of the species in the Atlantic Ocean and Mediterranean Sea were reviewed by Edwards (1966). Sailing characteristics of the species were investigated in a wind tunnel by Francis (1991). Early on considered siphonophores and later as “chondrophores,” both V. velella and P. porpita are now classified amongst the hydroids, as anthoathecates (Calder 1988, 2010; Schuchert 2010, 2012a, b). Sometimes reported from Florida as Velella mutica Lamarck, 1801, that binomen is considered a junior synonym of V. velella (Calder 1988; Schuchert 2010). Reported distribution. Atlantic coast of Florida. “ Coast of Florida ” (L. Agassiz 1862, as Velella mutica).— Cape Florida (A. Agassiz 1865, as V. mutica).— Gulf Stream; Straits of Florida (Fewkes 1886, as V. mutica).— Miami area (Bayer 1963). Western Atlantic. New England (A. Agassiz 1883, as Velella mutica) to Argentina (Oliveira et al. submitted), including Bermuda (Calder 1988), the Gulf of Mexico (Calder & Cairns 2009), and the Caribbean Sea (Fewkes 1885, as V. mutica). Elsewhere. Circumglobal in tropical and temperate waters (Calder 2010; Schuchert 2012b).
