Etymology: Artediellus: Petrus (Peter) Artedi, (10 Mar.) 1705-35 (28 Sep.), a son of a clergyman from Anundsjö named Olaus Arctaedius, in the northern part of Sweden.In 1729 he changed his name from Arctaedius to Arctædi, a name still later simplified to Artedi (Ref. 45335).

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 35388); 10.6 cm SL (female); common length : 10.5 cm TL male/unsexed; (Ref. 4698)
Gill membranes joined to each other under the throat, lateral line scales without bony knobs. Upper spine of the front gill cover curved upwards (Ref. 35388).
Occur on sandy or muddy bottoms (Ref. 4698). Benthic (Ref. 58426). Feed on polychaetes, small mollusks and very rarely small crustaceans (Ref. 4698). Lives at temperatures of -1.7-4°C. Females lay 50-350 eggs with a diameter of 4mm in late summer (Ref. 35388).
