Life Cycle ( Anglèis )

fornì da Fishbase
During courtship, 'the male follows the female and, after both enter dense vegetation (e.g. filamentous algae), the male forms a complete ring around the female's body behind the dorsal as the female releases the eggs' (Ref. 59043).

Biology ( Anglèis )

fornì da Fishbase
Found in burrows mostly in sandy to silty substrate in still to moderately flowing waters during the day. May sometimes inhabit gravel bottom and vegetation (Ref. 59043). Oviparous, possibly with distinct pairing during breeding similar to congeners (Ref. 205). Threatened due to small distribution range, habitat alterations and risk of hybridisation with C. hellenica (Ref. 59043).

Cobitis arachthosensis ( Anglèis )

fornì da wikipedia EN

Cobitis arachthosensis is a species of ray-finned fish in the true loach family (Cobitidae). It is endemic to Greece.[1]

It belongs to the subgenus Bicanestrinia, together with C. hellenica, C. meridionalis, and C. trichonica. According to cladistic analysis of DNA sequence data (nDNA RAG-1 and S7 ribosomal protein intron 1, and mtDNA cytochrome b), the first of these is an extremely close relative and the present species might arguably be included in it. C. hellenica occurs in the Louros and Thiamis River basins, parapatric to the range of C. arachthosensis.[3][4]

Its natural habitats is the Arachthos River basin. It is threatened by habitat loss.[1]
