A pod of dolphins hunting and feeding on a school of fish is an example of.... A. a population interaction. B. a community interaction. C. an ecosystem interaction. D. a biome interaction.
Bottlenose dolphins appear to sometimes work in groups to herd and catch fish and other prey. They organise themselves in wide groups, rather than concentrated groups. Herding may involve the group circling the smaller fish whilst one dolphin at a time takes its turn to go in and feed, or it may involve herding them up onto a sandbank or reef. Sometimes, a couple of the dolphins in the group, or pod, will dive beneath a school of fish, virtually pushing them upward to the rest of the dolphins waiting to feed. They have even been observed hitting the fish with their tails to temporarily stun them. Bottlenose dolphins will not eat all the resources in one area, but always leave some and move on to new feeding grounds. Bottlenose dolphins eat many kinds of fish, squid, shrimp and small rays and sharks. ~Quoted from the answer to a similar question: "How does a bottlenose dolphin get its food?"
