Definition
'Genus Pollachius' refers to the biological classification grouping that includes pollock and saithe (coalfish). It's like saying they belong to the same family. The genus level is above species but below family in the taxonomic hierarchy. Think of it as a mid-level grouping used to organize living things based on shared ancestry and characteristics. It helps scientists categorize and study these fish more effectively. So, 'genus Pollachius' is just the formal way of saying 'pollock and saithe's family'.
