Taxonomy
Name
The English word "char[r]" is thought to derive from
Old Irish ceara /cera meaning "[blood] red,"
[5] referring to its pink-red underside.
[6]
[7] This would also connect with its
Welsh name torgoch , "red belly."
[8]
The species name obtusus is Latin for "blunt."
Biology
Salvelinus obtusus is
benthopelagic and can grow up to 18 cm (7.1 in). It is distinguished from other
Salvelinus in Ireland by its obtuse
snout , rounded
dorsal profile and short lower
jaw , which is included in the upper jaw when the mouth is closed.
[9] Its body depth is 20–25% of snout length.

[11]
Range
Salvelinus obtusus is only found in
Muckross Lake and
Lough Leane , and is threatened by
eutrophication .
It was formerly found in
Lough Tay ,
Lough Dan ,
[12]
[13]
Lough Nalughraman and
Lough Acoose ,
[14] but is now considered extirpated at those sites and is
critically endangered .
