Blackwing Searobin

Prionotus rubio

The Blackwing Searobin, belonging to the family Triglidae, is a distinctive marine fish known for its broad pectoral fins, which feature a unique blue margin on the lower edge. These fins have modified rays that resemble legs, aiding in benthic locomotion and allowing the fish to probe the substrate for prey. This species is typically found in the Western Atlantic, ranging from North Carolina to the Yucatán Peninsula, with a notable presence in the Gulf of Mexico. Blackwing Searobins inhabit marine and brackish environments, often found from bays and estuaries to the mid-shelf, usually at depths of 11 to 13 meters. The majority of recorded sightings are at depths shallower than 40 meters. As a demersal predator, it feeds on a variety of small benthic invertebrates, with a preference for crustaceans like brown shrimp, swimming crabs, and rock shrimp. Encountering a Blackwing Searobin during a dive can be an interesting experience as it uses its 'walking rays' to move along the sea floor. Although there is no dedicated fishery for this species, it is often caught as bycatch. The Blackwing Searobin is listed as Least Concern by the IUCN.
