Species often confused with {name}
Red scorpionfish
Scorpaena scrofa
Key differences: S. scrofa is generally larger (up to 50 cm), typically redder in coloration, and possesses a distinct pit behind the eye and on the occiput, which S. porcus lacks. S. scrofa also has more prominent dermal flaps and tentacles, especially on the lower jaw.
Small red scorpionfish
Scorpaena notata
Key differences: S. notata is smaller than S. porcus (max 20 cm) and often has a more reddish hue. A key distinguishing feature is a prominent black spot on the spiny dorsal fin between the 7th and 10th spines, which is usually absent or very faint in S. porcus. S. notata also has fewer pectoral fin rays (15-17 vs. 16-19 for S. porcus).
Madeira scorpionfish
Scorpaena maderensis
Key differences: S. maderensis is generally smaller (max 14 cm) and has a more compressed body. It typically has a dark blotch on the operculum (gill cover) and often a more uniform reddish-brown coloration without the strong mottling of S. porcus. The number of pectoral fin rays can also differ.
