Nimble Spray Crab
Nimble spray crabs, also known as "urchin crabs," are found in both the Atlantic and Pacific oceans. However, this crab likes to move and was recently discovered in the Mediterranean Sea. This behavior has given it the title of "most invasive decapod species to enter the Mediterranean."
Despite this intimidating title, nimble spray crabs only grow to about 3 inches in length. They are strict herbivores, feeding on various types of algae. They live almost exclusively among rocks and boulders, which they use to hide from fish and predatory invertebrates.
Debelius Cleaner Shrimp
Debelius cleaner shrimp can be found throughout the Indo-Pacific, and are also referred to as fire shrimp, blood shrimp or scarlet cleaner shrimp. As indicated by these various names, this shrimp is a bright scarlet color, with white dots and white tips on its third to fifth pereiopods.
Evidenced by their name, the debelius cleaner shrimp play a cleaning role in their reef environments. These shrimp clean parasites and dead tissue from the reef, along with scraps of food not consumed by other animals. Growing to about an inch in length, these shrimp are small but mighty when it comes to cleaning up their reef environments!
