If you only need the buying answer
The cheapest short-term routes for Animal Physiology are rental and short digital access, not the current hardcover listing. But the current hardcover is almost identical to the sampled used-hardcover market and dramatically below the sampled new-hardcover market. So if you want ownership rather than temporary access, the current hardcover still has a strong case.

This is another split market. Rental and short eText win on immediate cost. But the current hardcover is close enough to the used-hardcover market and so much lower than the new-hardcover market that ownership is still defensible for readers who expect long-term use.
What this book actually teaches
An animal-physiology text matters because it teaches how organ systems, regulatory processes, adaptation, and comparative biological function fit together across species. A good physiology book is often not something students outgrow after a single exam because the same systems-level reasoning returns in upper-level biology, veterinary, and animal-science work.
That is why ownership can still make sense. A durable physiology reference can remain useful later in advanced coursework or professional pathways. The market simply says that if you only need the material briefly, cheaper access exists.
Who should choose short-term access and who should buy hardcover
Choose rental or short digital access if your only goal is lowest short-term cost. Buy the hardcover if you want a kept physiology reference and prefer ownership over temporary access. In the current market, short-term access wins on price and hardcover wins on ownership value.
