One of the most common findings is that juvenile squid (>200 mm ML) consume a greater percentage of crustaceans and cephalopods compared to their size than mature squid, which consume a large percentage of fish and virtually no crustaceans.
In general, juvenile squid (over 200 mm in mantle length) eat more crustaceans and cephalopods compared to their size than adult squid, who mostly eat fish with very little consumption of crustaceans.
