Types of Prey Consumed
Fish Varieties
Fish varieties constitute a significant portion of the orca diet. These fish, including salmon, herring, and mackerel, provide essential nutrients for the orcas' survival. One key characteristic of fish in their diet is the high protein content, aiding in muscle development and overall health. Additionally, the Omega-3 fatty acids found in fish are vital for maintaining the orcas' neurological functions. While fish are a popular choice for orcas due to their abundance and nutritional value, changes in fish populations can significantly impact the orcas' dietary patterns and health.
Cephalopods
Cephalopods like squid and octopus are another vital component of the orca diet. These marine mollusks offer a more diverse range of nutrients, including essential minerals like copper, zinc, and manganese. One unique feature of cephalopods is their high intelligence, presenting a challenge for orcas during hunting.
