What does a whale eatwhich a barracuda dosent eat?

Whales primarily consume krill, small fish, and other marine organisms depending on the species, while barracudas mainly feed on smaller fish and squid. The significant difference lies in the size and type of prey: whales can consume large swarms of tiny organisms like krill, which barracudas do not eat. Additionally, some whales, like baleen whales, filter-feed on tiny plankton, a food source not targeted by barracudas.
