Scientific Name: Parablennius ruber (Valenciennes, 1836)
Common Name(s):
English Portuguese Blenny
French Blennie Rouge

Taxonomic Notes: Based on molecular data, Parablennius ruber is a sister species of Parablennius gattorugine, with which it forms a very differentiated clade within the genus Parablennius (Almada et al. 2005). Its validity as a separate species has been confirmed by Almeida (1982) and Bath (1982).

Parablennius ruber is restricted to the northeastern Atlantic Ocean, where it is locally abundant and widespread. There are no known major threats towards this species at this time. Therefore, P. ruber is assessed as Least Concern.

Geographic Range [top]

Range Description:Parablennius ruber is found in the eastern Atlantic. It was thought to be restricted to Portuguese waters (mainland Portugal, Azores, and Madeira). However, P. ruber has been recorded from western Britain and Ireland (Goodwin and Picton 2007) and is therefore likely distributed more widely along western Europe (Almada et al. 2007). It is found from two to 30 m, but preferably at five metres (Zander 1986, Harmelin-Vivien et al. 2001). As this species has previously been confused with Parablennius gattorugine, a revision of the distribution of Parablennius ruber is needed.
Countries occurrence:
France (France (mainland)); Ireland; Portugal (Azores, Madeira, Portugal (mainland)); Spain; United Kingdom (Great Britain, Northern Ireland)

Population [top]

Population:Parablennius ruber is commonly observed in rocky shores of the Azores, most frequently to 10 m depth, but down to 30 m. The number of individuals observed per census (350 to 450 m2) was 2.56 (0 to 10 m), 1.00 (11 to 17 m), and 0.87 (18 to 25 m) (Harmelin-Vivien et al. 2001).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Parablennius ruber inhabits rocky shores and is found solitary or in groups of five to 15 (Zander 1986). The size of first sexual maturation is estimated to be equal or greater than six centimetres for females and the maximum reported size is 14.1 cm total length (Azevedo and Homem 2002, Tsikliras and Stergiou 2014). The diet of P. ruber is dominated by red algae, sponges and amphipods, though it may also consume gastropods and isopods (Azevedo and Homem 2002).
Movement patterns:Not a Migrant
