What reliable identification marker on M. merlangus differs significantly from the corresponding feature on haddock?
Answer
The size and definition of the dark spot at the pectoral fin base
A crucial visual distinction used by anglers and consumers when comparing *Merlangius merlangus* to haddock involves the dark spot located near the pectoral fins. While both species possess such a mark, the spot on the haddock is specifically described as being larger and more defined, sometimes referred to as a thumbprint. Furthermore, the lateral line color provides another key differentiation: *M. merlangus* features a brown lateral line, whereas haddock possesses a distinct black lateral line. These subtle yet consistent differences are essential for accurate species identification, especially since the overall body structure can appear similar.
