Although you may have seen octopuses in books and TV shows, pictures do not do justice to the fascinating features of this aquatic animal. Signing up for a Hawaiian snorkeling adventure is the best way to observe these oceanic creatures. Before you embark on an enlightening trip, review these four fun facts about octopuses.

Snorkeling Experts Share 4 Octopus Fun Facts

They Have Existed for Millions of Years

Scientists estimate that octopuses have existed in some form for more than 296 million years. They have drawn this conclusion after researching the fossils of an animal that bore close semblance to present-day octopuses.

Octopuses Have Blue Blood

SnorkelingThe blood of an octopus is blue because it contains copper, which transports oxygen throughout their body. Known as hemocyanin, the protein in their copper-based blood helps them survive cool temperatures in the deepest parts of the ocean. 

Much of an Octopus’ Brain Is in Its Arms

Around two-thirds of an octopus’ brain is located in its arms, which allows it to perform many different tasks at the same time. In fact, octopus arms retain their sensitivity even after they are disconnected from the body.

They Have 3 Hearts

While one octopus heart supplies blood to its organs, the other two keep the oxygen in circulation past its gills. The heart pumping blood to its organs stops beating once this sea creature starts swimming. Experts believe this is reason octopuses prefer walking across the ocean floor instead of swimming.
