Atlantic smooth-dogfish

The Atlantic smooth-dogfish (Mustelus canis) is a species of houndshark belonging to the order Carcharhiniformes. It is essential to clarify that this animal is exclusively a marine fish species inhabiting the coastal waters of the Western Atlantic. It has no biological connection to terrestrial agriculture and is in no way classified as a plant pest.

From a systematic perspective, Mustelus canis is categorized within the class Chondrichthyes (cartilaginous fishes) and the family Triakidae. Its ecological role is that of a benthic predator, primarily feeding on crustaceans such as crabs and lobsters, as well as small fish. It lacks any anatomical or behavioral characteristics that would enable it to interact with or damage crops.

The biology and lifecycle of the smooth-dogfish are restricted to marine environments. These sharks are ovoviviparous and spend their entire existence in saltwater habitats. Because they cannot survive or move outside of an aquatic environment, they are incapable of interacting with agricultural fields, greenhouses, or garden plants.

Regarding damage or economic impact on crops, there is no evidence or scientific basis to categorize this species as a pest. There is no such thing as "damage" caused by this fish to agricultural plants, as it does not consume, infect, or physically compromise any vegetable or fruit crops. It represents zero threat to farmers or commercial agriculture.

No protection measures, control strategies, or mitigation techniques are required for this species in an agronomic context. Labeling this shark as a pest is a common database error. Farmers should focus their efforts on monitoring traditional agricultural threats such as insects, weeds, and fungi, rather than marine life which poses no danger to crop health.
