The accompanying illustration represents Fishes of the Mediterranean Sea, and it is probable that one of them may be identified, though the passage in which it is mentioned is only an inferential one. In the prophecy against Pharaoh, king of Egypt, the prophet Ezekiel writes as follows: "I will put hooks in thy jaws, and I will cause the fish of thy rivers to stick unto thy scales, and I will bring thee up out of the midst of thy rivers, and all the fish of thy rivers shall stick unto thy scales" (xxix. 4).
Reference is here made to some inhabitant of the waters that has the power of adhesion, and two suggestions have been made respecting the precise signification of the passage. Some commentators think that the "Fishes" here mentioned are the Cuttles, which, although they are not Fishes at all, but belong to the molluscs, are called Fishes after the loose nomenclature of the Hebrew language, just as, even in our stricter and more copious language, we speak of the same creature as the Cuttle-fish, and use the word "shell-fish" to denote both molluscs and crustacea.
Others believe that the prophet made allusion to the Sucking-fish, which has the dorsal fins developed into a most curious apparatus of adhesion, by means of which it can fasten itself at will to any smooth object, and hold so tightly to it that it can scarcely be torn away without injury.
The common Sucking-fish (Echeneis remora) is shown in the upper part of the illustration.
There are, however, other fish which have powers of adhesion which, although not so remarkable as those of the Sucking-fish, are yet very strong. There is, for example, the well-known Lump-sucker, or Lump-fish, which has the ventral fins modified into a sucker so powerful that, when one of these fishes has been put into a pail of water, it has attached itself so firmly to the bottom of the vessel that when lifted by the tail it raised the pail, together with several gallons of water.
The Gobies, again, have their ventral fins united and modified into a single sucker, by means of which the fish is able to secure itself to a stone, rock, or indeed any tolerably smooth surface. These fishes are popularly known as Bull-routs.
The centre of the illustration is occupied by another of the Mediterranean fishes. This is the well-known Tunny (Thynnus thynnus), which furnishes food to the inhabitants of the coasts of this inland sea, and indeed constitutes one of their principal sources of wealth. This fine fish is on an average four or five feet in length, and sometimes attains the length of six or seven feet.
The flesh of the Tunny is excellent, and the fish is so conspicuous, that the silence of the Scriptures concerning its existence shows the utter indifference to specific accuracy that prevailed among the various writers.
The other figure represents the Coryphene (Coryphæna hippuris), popularly, though very wrongly, called the Dolphin, and celebrated, under that name, for the beautiful colours which fly over the surface of the body as it dies.
The flesh of the Coryphene is excellent, and in the times of classic Rome the epicures were accustomed to keep these fish alive, and at the beginning of a feast to lay them before the guests, so that they might, in the first place, witness the magnificent colours of the dying fish, and, in the second place, might be assured that when it was cooked it was perfectly fresh. Even during life, the Coryphene is a most lovely fish, and those who have witnessed it playing round a ship, or dashing off in chase of a shoal of flying-fishes, can scarcely find words to express their admiration of its beauty.
