Type locality

Black Sea.

Distribution

Mediterranean; South Africa; South Arabia coast; Bermuda; Venezuela; Brazil; Hawaii; northeastern Pacific; Australia ( McCain and Steinberg 1970; Krapp- Schickel 1993; Guerra-García 2004; Diaz et al. 2005).

Records in the Gulf of Mexico

MEX: Mexican ridges at southwest ( Winfield et al. 2006). USA: Loggerhead Key ( McCain 1968).

Habitat

Caprella danilevskii has been found on algae, seagrasses, sponges, tunicates, bryozoans ( McCain 1968), clinging on different species of algae along the coast of Ceuta, North Africa with high hydrodynamics (Guerra-García 2001), as well as on algae of the Caribbean coastlines of Venezuela and Colombia ( Diaz et al. 2005; Guerra- García, Krapp-Schickel, et al. 2006). The depth range reported is shallow water extending to 2620 m ( Winfield et al. 2006; Winfield, Escobar-Briones, et al. 2007; Winfield and Escobar-Briones 2008; LeCroy et al. 2009).

Remarks

According to McCain (1968) and Guerra-García (2006), C. danilevskii is easily distinguished from the other species of Caprella by its elongate gills with long axis parallel to body, the distinctive male abdomen with a pair of appendages hooked distally, the absence of grasping spine in the pereopods, and the short dactylus on the male ganathopod 2.

Caprella danilevskii has been studied in detail, especially its life history ( Takeuchi and Hirano 1991, 1992) and the toxic effects of tributyltin ( Takeuchi et al. 2001; Ohji et al. 2004).
