Scarlet shrimp

Plesiopenaeus edwardsianus, known as the scarlet shrimp, is a deep-sea crustacean species within the order Decapoda and the family Aristeidae. It is essential to clarify that this organism is not a plant pest. Reports labeling this species as a pest affecting agricultural crops are scientifically incorrect and arise from a fundamental misunderstanding of its habitat and biological requirements.

The scarlet shrimp is strictly adapted to marine environments, typically inhabiting the continental slopes at depths ranging from 400 to 1800 meters. Its biology is entirely focused on surviving in high-pressure, cold-water abyssal zones. The diet of this shrimp consists of small benthic organisms and organic marine debris, which is incompatible with the nutritional requirements of herbivorous plant-consuming pests.

There are no documented cases of Plesiopenaeus edwardsianus causing damage to crops. As an obligate marine species, it lacks the physiological capacity to survive in freshwater or terrestrial environments, such as garden soils or greenhouse setups. It cannot physically interact with plants, nor does it possess the biological adaptations to feed on terrestrial flora.

The life cycle of the scarlet shrimp occurs exclusively in oceanic waters. Reproduction and larval development take place in the water column, far removed from any agricultural land. These crustaceans are highly specialized animals that serve as an important link in the deep-sea food web, feeding on plankton and detritus within the ocean depths.

• Classification: Arthropoda / Malacostraca / Decapoda / Aristeidae.
• Distribution: Deep waters of the Atlantic, Pacific, and Indian Oceans.
• Economic impact: Commercial target for deep-sea fishing; no agricultural significance.

No protective measures are required for this species regarding plant protection. Any advice suggesting pesticides or traps for this shrimp in a farming context is misleading. As agricultural professionals, we emphasize that scientific verification is necessary when identifying pests, as species like the scarlet shrimp are beneficial or neutral members of marine ecosystems, posing absolutely no threat to plants.
