Inktober Day 23: Sea Pen



Day 23: Sea Pen



Is it a quill? Is it a feather? Nope! It’s a sea pen!

In a similar way in which corals live in colonies, the sea pen is a group of invertebrates marine animals that live around a central “stalk” (which is actually a polyp that morphs to have a bulb at the bottom to anchor the pen to the sea floor!) and looks like one of those old fashioned quill pens! Sea pens are amazing critters and can even grow up to 6ft tall!
