Description

Habitat

Biome: Marine .

Ecology: The common guitarfish is a bottom dwelling species with an aplacental viviparous mode of reproduction mode (the maternal adult gives birth to live young which do not have a yolk sac placenta). It can be found over sandy, muddy, shell and occasionally macro-algal covered substrates (Whitehead et al. 1984, De Buen 1935). It inhabits shallow waters in the intertidal zone to waters of up to 180 m in depth. This guitarfish tends to swim slowly along the sea bottom or partially buries itself under the substrate, feeding upon benthic invertebrates and fish (Patokina and Litvinov 2005). Scientific trawl surveys in Moroccan waters recorded the depth range of the common guitarfish as 17 to 80 m in depth (M. Hicham and A. Mouni pers. comm. 2006). Bottom trawl surveys carried out off the coast of Sierra Leone indicate that this is a sublittoral species which occurs between 10 and 100 m in depth. It was only found in waters deeper than 50 m during the summer and autumnal months and during the winter-spring seasons this guitarfish moves northwards (Litvinov 1993).

Whitehead et al. (1984) reported the maximum size of the common guitarfish as approximately 100 cm in total length (TL ). However, within the Southern Mediterranean (the Gabés Gulf ), the maximum reported sizes were slightly larger with 140 cm TL for males and 162 cm TL for females (Capapé et al. 1996). Males reach maturity at 75 cm in TL, females at 85 cm TL. The age at maturity is not known for either sex, nor the longevity of this species. The females have between one and two litters per year, with the gestation period spanning four months. Between 4 and 6 pups are produced per litter, measuring 30 cm at birth.

There is no information available on the natural rate of mortality that this species population experiences, or any further details on its population and reproductive biology . [1].
