Ruber

Academic Name: Globigerinoides ruber

Type: Planktonic (surface-dweller)

Rarity: Common (60%)

Description: Identifying a ruber is all about spotting the "hoodie". Look for a distinct, three-chambered arrangement where the final chamber sits like a person wearing a hoodie with the hat standing straight up. Unlike its cousin, all its chambers look round, aligned and perfect (somethings the third chamber might not tho).  Under the microscope, you'll notice a classic "pitted" or "honeycomb" texture across the surface. And if you spot a pink one, congratulations! They were already extinct 120,000 years ago in the Indian & Pacific Oceans!
