Royal Red Shrimp: Everything You Need to Know About Pleoticus robustus

What is Royal Red Shrimp?

Royal Red Shrimp (Pleoticus robustus), a decapod crustacean belonging to the family Solenoceridae, has emerged as a highly sought-after species in the seafood industry. Boasting a unique flavour profile and striking red coloration, these shrimp have become popular for their culinary applications. This article delves into the various aspects of Royal Red Shrimp, elucidating their biology, distribution, ecological significance, and commercial value.



Royal Red Shrimp possess a robust, cylindrical body of approximately 15-20 cm long. Their body consists of a cephalothorax and a segmented abdomen, which terminate in a fan-like telson and uropods. The exoskeleton is characterized by a vibrant red coloration, distinguishing them from other shrimp species. The red hue is attributed to astaxanthin, a carotenoid pigment.


The reproductive process of Royal Red Shrimp is marked by sexual dimorphism, with males being smaller than females. The mating process involves the transfer of a spermatophore from the male to the female, after which fertilization occurs internally. The female carries the fertilized eggs on her pleopods (swimming legs) until they hatch as planktonic larvae. The larvae then undergo multiple moults before developing into juveniles and eventually reaching adulthood.

Distribution and Habitat


The Royal Red Shrimp has a relatively wide distribution, primarily found in the Western Atlantic, ranging from North Carolina to Brazil, including the Gulf of Mexico and the Caribbean Sea.


These shrimp inhabit deeper waters, typically found at depths of 180 to 730 meters, although they can occasionally be found in shallower regions. They favour muddy or sandy substrates, where they can burrow to escape predators and search for food.



Royal Red Shrimp are omnivorous, with their diet consisting of a diverse range of organisms, including detritus, plankton, small fish, and other invertebrates. Their feeding habits contribute to the cycling of nutrients in the benthic ecosystem.


Various marine species prey on Royal Red Shrimp, including fish such as groupers, snappers, and demersal sharks. Predation is crucial for maintaining a balanced ecosystem and ensuring population control.

Commercial Importance and Sustainability:


The Royal Red Shrimp has experienced a surge in commercial value due to its unique taste and colour. The species is primarily caught using trawls or traps, with the United States, Mexico, and Brazil being the primary harvesters.


The deep-water habitat of the Royal Red Shrimp has resulted in lower fishing pressure than other shrimp species, contributing to its relative sustainability. However, sustainable management practices, such as size-selective gear and seasonal closures, are necessary to prevent overexploitation.

Climate Change Implications:

The potential impacts of climate change on the Royal Red Shrimp are not yet fully understood. Temperature, ocean acidification, and alterations in current patterns may affect their distribution, reproductive success, and habitat preferences. Research is ongoing to assess the potential consequences and inform adaptive management strategies to ensure the long-term viability of Royal Red Shrimp populations.


As ocean temperatures continue to rise due to climate change, the thermal preferences of the Royal Red Shrimp may shift. This could alter their distribution, potentially affecting the species’ geographical range and local abundance. Additionally, temperature changes may impact their reproductive success and the availability of prey resources.

Ocean Acidification

Increasing carbon dioxide levels in the atmosphere have led to ocean acidification, which can harm marine organisms, particularly those with calcified structures. Although the impact of ocean acidification on the Royal Red Shrimp is not yet clear, it could potentially affect their growth, development, and survival.

Current Patterns

Climate change can alter oceanic current patterns, which may impact the dispersal of Royal Red Shrimp larvae and the distribution of their prey. This could have implications for the connectivity of populations, genetic diversity, and overall resilience to environmental changes.

How to Cook Royal Red Shrimp

Royal Red Shrimp are renowned for their rich flavour and tender texture, making them an excellent choice for various culinary applications. Here are a few ways to prepare and enjoy this delicious crustacean:

Royal Red Shrimp Scampi

Sauté minced garlic in butter and olive oil over medium heat until fragrant. Add the peeled and deveined shrimp, cooking for 1-2 minutes per side until they turn pink. Deglaze the pan with white wine, and add lemon juice, salt, and red pepper flakes. Cook for another 2 minutes before adding chopped parsley. Serve the shrimp scampi over pasta or with crusty bread.

Royal Red Shrimp and Grits

Cook grits according to package instructions, adding butter and grated cheese for a creamy texture. In a separate pan, cook bacon until crispy, then set aside. In the same pan, sauté diced onion and bell pepper until tender. Add the shrimp and cook until pink and opaque. Stir in a mixture of chicken broth, Worcestershire sauce, and hot sauce, and simmer until the sauce has thickened. Serve the shrimp and sauce over the prepared grits, and garnish with crumbled bacon and chopped green onions.

Royal Red Shrimp Ceviche

Combine diced Royal Red Shrimp with fresh lime juice, diced tomatoes, onions, jalapeños, and chopped cilantro. Allow the mixture to marinate in the refrigerator for at least 30 minutes or until the shrimp have turned opaque due to the acidity of the lime juice. Serve the ceviche with tortilla chips, sliced avocado, and hot sauce.
