Red-spotted Goby Shrimp

The Red-spotted Goby Shrimp, also known as the Red-spotted Snapping Shrimp (scientifically referred to as Alpheus rubromaculatus or sometimes Alpheus karplusi), is a fascinating tropical marine species found in the 🌊 Western Indian Ocean, including regions like the 🌊 Red Sea near 🇸🇦 Saudi Arabia, 🇪🇬 Egypt, and 🇮🇱 Israel. This small to medium-sized shrimp typically grows to about 3 to 5 centimeters (1.2 to 2 inches) in length and is recognized by its translucent white body adorned with distinct red spots or markings, particularly on its carapace and appendages.

These shrimp inhabit depths ranging from 5 to 40 meters (16 to 131 feet) and are benthic creatures, meaning they live on the sea floor. They are known for their unique symbiotic relationship with the White Cap shrimp goby (Lotilia graciliosa). In this partnership, the goby acts as a lookout, standing guard outside the burrow and warning the shrimp of potential dangers.

One of the shrimp's most notable features is its large claw, which serves as a multifunctional tool. This claw is capable of producing a loud snapping sound by creating a cavitation bubble, which can be used to stun prey or ward off predators. This distinctive snapping behavior is a characteristic feature of the Alpheidae family and is crucial for the shrimp's survival. As an opportunistic feeder, the Red-spotted Goby Shrimp consumes a variety of small invertebrates, detritus, and organic material.

Interestingly, although the shrimp is often referred to as Alpheus rubromaculatus, the World Register of Marine Species (WORMS) notes that this specific name has never been officially published and is thus considered a nomen nudem, or an unpublished name.
