Starburst Anemones have lines radiating out in all directions from their oral disk, Giant Green Anemones have none. The most reliable way to tell Giant Green Anemones from Starburst Anemones is to look at the coloring in the middle of their bodies (on their oral disk). Other Info - Their lifespan is estimated to reach upwards of 80-150 years old.Size? - Approximately 6-10 inches in diameter.When not submerged they tend to appear dark green or even brown-ish. But this color is usually only found on anemones that are submerged under water and relatively close to the surface, receiving plenty of sunlight. Colors? - Famously a bright, vivid green.They’re commonly seen attached to rocks or manmade structures like support columns for bridges or piers. Where? - Found around the low to middle tide zones, along the entire west coast.Sunlight plays a role in producing the green pigment seen on most starburst anemones. If you see an anemone with gray or even white coloring, that means they probably spend most of their time in the shade under rocks. Other Info - These are the most common non-aggregating anemones around.Size? - Generally about 5-10 inches in diameter.Colors? - Typically somewhere between bright green and pale green, but you can also find them closer to the yellow and grayish end of the spectrum.Where? - Most likely to be found around southern California, where the water temperature is a bit warmer.Tide pool visitors should take extra caution not to step on them when walking along rocks, as they are regularly covered in sand, bits of shell, and other ocean debris. They are quite small but they tend to live in large tightly-packed colonies, which can give the appearance of one large moss-like lifeform. Other Info - This is the most common anemone you’ll find on the west coast.Those found in the colder waters of the Pacific Northwest tend to be on the smaller side of the range, about 1-inch across.

But when they’re closed they look more like a gray-ish, rocky, shell-covered mess. Colors? - Usually a pale-green color when open.Regularly seen throughout California, Oregon & Washington. From the low end of the middle tide zone, to the high tide zone. Where? - Usually seen at or above sea level.These zones are split up based on how much time they spend submerged in water or exposed to the air.įor the purpose of this article, we will try to avoid getting lost in the details of the different intertidal zones, and focus our energy on the interesting, colorful and sometimes freaky lifeforms that you’ll find in tide pools up and down the west coast. However, the intertidal zones are then further divided into high tide, middle tide, low tide, and a lesser used fourth category called the spray zone. According to NOAA (the National Oceanic and Atmospheric Administration), tide pools are isolated pockets of seawater that are found in “intertidal” zones-which are just areas where the ocean meets the land. Let’s start with an oversimplified review of what tide pools are.

The sunny shores of southern California are home to some dramatically different sea life than the creatures you’ll find living in the cold waters of the pacific northwest, and learning the differences could take you a lifetime. But the types of tide pool creatures you’ll find will change, depending on where you’re looking and where you are. There’s a truly mind-bending variety of creatures living in tide pools up and down the west coast of the United States. Their eco-conscious, coral reef-safe sunscreens will protect your skin and our tide pool friends alike. This article about tide pool creatures is brought to you by Stream2Sea.
