Red Sea goby Red Sea goby The Red Sea goby (Silhouettea aegyptia) is a species of true goby from the family Gobiidae. It was once a species confined to the Red Sea but it has colonised the Suez Canal and the south-eastern Mediterranean by Lessepsian migration. The Red Sea goby is marked with many dark vertical spots which have reddish brown edges on a cream background colour. There are 9 or 10 dark spots along the lateral line. It has a short snout and in males the first spine of the first dorsal fin is elongated. There are no scales on the head
Mediterranean Sea some lessepsian species have proven to be considerable mainly in the Levantine basin of the Mediterranean, where they are replacing native species and becoming a "familiar sight". According to the International Union for Conservation of Nature definition, as well as Convention on Biological Diversity (CBD) and Ramsar Convention terminologies, they are alien species, as they are non-native (non-indigenous) to the Mediterranean Sea, and they are outside their normal area of distribution which is the Indo-Pacific region. When these species succeed in establishing populations in the Mediterranean Sea, compete with and begin to replace native species they are "Alien Invasive Species",
