The eye-spot umber ( Leiostomus xanthurus ), known as the spot or spot croaker in the USA , is a small umber fish . The eye spot (above the base of the pectoral fin, on the shoulder girdle) probably serves to irritate potential predators. The color is the bluish to purple shimmering light silver common in Umberfishes; approx. 18 yellow oblique bandages fade more and more with increasing size. The scientific name Leiostomus xanthurus means "yellow-tailed smooth-mouthed", which is supposed to indicate his whisker . It has 25 vertebrae. The spot can reach 35 cm, but most of the ones you catch are much smaller and weigh less than 1/2 pound, because as an excellent, tender fish it is stalked a lot and it rarely reaches its maximum age. Nevertheless, it should still represent the most individual species of the Sciaenids on the US east coast. Every year at the end of September , the “Spot Festival” in Hampstead , North Carolina , shows how popular it is .
Fin formula : D1 XIII-XVI, D2 I / 30-33, A II / 12-15.
It occurs on the east coast from Massachusetts to Cuba and in the entire Gulf of Mexico , always near the coast at shallow depth, over sand and mud bottom, from which it extracts worms, crabs and small clams. The mouth is a little subordinate. His fondness for brackish water estuaries and lagoons is unmistakable, especially among juvenile fish, which develop here over the summer, initially eating plankton (from pelagic eggs, often spawning in portions). It is fast growing and only lives a few years.
Is very similar to the earlier also to the genus Leiostomus counted White Umber ( Genyonemus lineatus ) from the North American west coast.
