Scandia gigas ( Pieper, 1884) 

Fig. 76View FIGURE 76 A –C

See Boero et al. (1997 a) for a complete synonymy.

Material examined. HCUS-S 0 83 (Hydrozoa Collection, University of Salento—fauna of the Salento Peninsula).

Description (based on our own observations; Boero et al. 1997 a):

Hydroid. Colonies stolonal; hydrocauli as erect pedicels scarcely, dichotomously or irregularly branched and ended in hydrothecae, perisarc undulated or twisted throughout; hydrothecae tubular, elongated, walls sometimes asymmetrical, narrowing gradually towards the base, with a hydrothecal diaphragm, margin everted, rim even. Gonothecae: female gonothecae spherical, male ones sac-shaped and elongated.

Cnidome. Microbasic mastigophores.

Habitat type. Littoral and shelf species that has been found from the tidal level to about 90 m depth in the Mediterranean Sea ( Boero & Fresi 1986; Roca 1986).

Substrate. Hydroids, algae, Posidonia  , other organisms such as bryozoans, sponges, anthozoans, polychaete tubes, bivalve and gastropod shells, cirripedes, ascidians, and non-living substrata.

Seasonality: July –April ( Boero & Fresi 1986) in the Ligurian Sea; January, April –June, August, September, November (for a review see Bouillon et al. 2004); January –December (De Vito 2006; this study) in Salento waters.

Reproductive period. April (Gili 1986); July ( Broch 1933); July –August ( Peña Cantero & García Carrascosa 2002); August –September ( Boero & Fresi 1986) in the Mediterranean Sea.

Distribution. Temperate waters Atlantic and Pacific, Mediterranean ( Stechow 1919; Broch 1933; Fraser 1946; Patriti 1970; Marinopoulos 1979; Isasi 1985; Altuna 1994; Medel & López-González 1996; Boero et al. 1997 a; Peña Cantero & García Carrascosa 2002; Bouillon et al. 2004; Galea 2008; Gravili et al. 2008 a; Puce et al. 2009; Soto Ãngel & Peña Cantero 2013).

Records in Salento. Moderately frequent in the following localities: Grotta del Ciolo ( Moscatello & Belmonte 2007); Il Chiapparo, Otranto (De Vito 2006; Gravili 2006; Gravili et al. 2008 a; this study).

Remarks. In the Mediterranean area many authors used the name Scandia pocillum  for Lafoea gigas Pieper, 1884  . Boero (1981 a) reintroduced the name S. gigas  since Cornelius (1975) showed that L. pocillum  is conspecific with L. dumosa  . Gonothecae and medusae not seen in the present study.
