“…There is high variability in the development of the fish retina, both intra and interspecifically (Evans & Browman, ). Thus, while altricial fish species, such as the turbot Scophthalmus maximus (L. 1758) (Doldán et al , ; Cid et al , ), the tench Tinca tinca (L. 1758) (Bejarano‐Escobar et al , ) or the Senegalese sole Solea senegalensis Kaup 1858 (Bejarano‐Escobar et al , ) hatch with an undifferentiated retina and do not complete retinal development until late in larval life, precocial fish species, such as the brown trout Salmo trutta L. 1758 (Candal et al , , ), the small spotted catshark Scyliorhinus canicula (L. 1758) (Ferreiro‐Galve et al , 2008, 2010 a , b , 2012; Bejarano‐Escobar et al , 2012 a , 2013) or the brown banded bamboo shark Chiloscyllium punctatum Müller & Henle 1838 (Harahush et al , ) complete their retinal development before hatching. Detailed comparative studies of additional species of fishes, examining maturational features such as histogenesis and cell differentiation, should advance understanding of interspecific differences.…”
