I was just thinking. Animals in the ocean have so much space. What guides their travel, and what "choices" are they making?

I understand the Earth's magnetic field, food, and maybe predators. What else is there?

There is so much to learn. Watch blue planet or something.. Put some time in.. this is more complicated than a paragraph on reddit.

Passed down knowledge, at least for killer whales. The southern residents pods were captured in Penn Cove in the 1970s and L pod decided to re-enter the cove after 54 years last year.
