Video shows juvenile jacks mimicking Striped Catfish

Over on the Blennywatcher Blog, Anna DeLoach has posted a video showing juvenile Bluespotted Trevally (Caranx bucculentus) that have adopted the striped coloration of the Striped Catfish (Plotosus lineatus). Jack expert, Dr. William Smith-Vaniz explained that this is likely a case of opportunistic mimicry and the jacks may benefit both from access to prey flushed out by the swarming catfish and protection from predators. This is the first time such behavior has been documented between the two species.
