Remarks. The original account of Turritopsis nutricula  by McCrady (1857) was based solely on the medusa stage. A previously unknown hydroid was linked to it in life cycle studies by Brooks (1883). While he provided no illustration of either hydroid or medusa of the species in that work, an excellent one appeared in another publication three years later ( Brooks 1886: pl. 37). The same drawing was included later in the monograph of Mayer (1910a: fig. 76).

McCrady’s (1857) description of T. nutricula  made no direct mention of the collection locale. However, his pioneering research on hydrozoans of the southeastern United States was carried out in Charleston Harbor and vicinity, South Carolina ( Stephens & Calder 1992). The type locality can therefore be taken to be the Charleston Harbor area. The species was described again in a classic paper on Hydrozoa of Charleston Harbor ( McCrady 1859), and specimens collected from Charleston, by McCrady, were included in a catalogue of the Museum of Comparative Zoology by A. Agassiz (1865).

In a report on anthoathecate hydroids of Bermuda ( Calder 1988), I wrote that the generic name Turritopsis  Mc- Crady was threatened by a virtually unused subjective synonym ( Clavula Wright, 1859  ). McCrady’s paper, in which Turritopsis  was first established, is now known to have been published in 1857 ( Calder et al. 1992) and not in 1859 as generally believed at the time. Turritopsis  therefore has priority over Clavula  , a name proposed by Wright (1959) in the July 1859 issue of Edinburgh New Philosophical Journal. For the same reason, the binomen Clavula gossii Wright, 1859  is not a nomenclatural threat to Turritopsis nutricula  . Indeed, the two species names are no longer held to be synonyms ( Schuchert 2004).

An account of the medusa of T. nutricula  by A. Agassiz (1865) from Naushon, Massachusetts, was based on a misidentification ( Brooks 1882; Mayer 1910a). Reports of the species (misspelled as T. nutricola  ) by L. Agassiz (1862) from the same location, in collections by A. Agassiz, are likewise excluded from distribution records below as likely misidentifications. So too is a report of it from Massachusetts, based on the records of L. and A. Agassiz, by Verrill (1874d: 454, 734). Recent fanciful accounts of the species as “the immortal jellyfish” have largely been based on misidentifications of the European T. dohrnii ( Weismann, 1883)  .

By the mid- and late 20 th century, both hydroid and medusa stages of T. nutricula  were widely thought to be almost circumglobal in distribution ( Kramp 1961; Calder 1988). Evidence from recent reproductive and molecular studies ( Schuchert 2004; Miglietta et al. 2007; Miglietta & Lessios 2009; Miglietta 2016; Kubota & Nagai 2018) indicate that the species is far more restricted in distribution, occurring largely or exclusively in the warm-temperate western Atlantic. As noted by Schuchert (2016), however, 16S sequences of specimens attributed to T. nutricula  thus far are inconclusive in having been based on specimens collected at considerable distances from the type locality in South Carolina. Analyses of topotypic material are needed to confirm results of those sequences.

Medusae of T. nutricula  are dioecious and oviparous ( Schuchert 2004), thereby differing from those of the European T. polycirrha ( Keferstein, 1862)  . Morphological characters distinguishing T. nutricula  from T. polycirrha  , the Mediterranean T. dohrnii  , and the Pacific T. rubra ( Farquhar, 1895)  are outlined in Schuchert (2004), with differences being most apparent in medusae of the species. The hydroid colony examined here from Fort Myers Beach lacked medusa buds, with identification of it as T. nutricula  being based largely on its occurrence within a biogeographic region related to that of the type locality of the species elsewhere in the southern United States. Moreover, medusae of T. nutricula  have been reported nearby from the Dry Tortugas in southwest Florida ( Mayer 1900b, 1910a; Vanhöffen 1916). Hydroids identified as the relatively deep water T. fascicularis Fraser, 1943  also occur in the region ( Fraser 1944; Calder 2013; Miglietta 2016), but they differ in having much larger, polysiphonic colonies. As for T. fascicularis  , it has now been linked through DNA sequence data to Oceania armata Kölliker, 1853  ( Schuchert 2016).

Turritopsis nutricula  has been reported infrequently in the Gulf of Mexico. As noted above, medusae of the species have been recorded at the Tortugas. Medusae were also collected in the Bahía de Campeche, Mexico, by Martell-Hernández et al. (2014). Earlier, Segura-Puertas (1992) reported the medusa stage from the Yucatan Shelf and the Mexican Caribbean, but it is unclear whether the species was collected in the Gulf of Mexico. The hydroid stage has been identified from coastal petroleum platforms in Texas ( Fotheringham 1981) and Louisiana ( Lewbel et al. 1987). Its reported range elsewhere in the western North Atlantic extends from southern Massachusetts to the southern Caribbean Sea (see records below). Records of T. nutricula  from South America are summarized in Oliveira et al. (2016).
