seven fins are on a sailfish.
Sailfish have fins, which they use as wings or sails. I have heard conflicting reports from various people who have real life experience, regarding the scales. There are several varieties of sailfish. It could be that some varieties have scales, and others do not. Both of my sources, which conflict with each other, are credible. However, each source lives on a different continent, and may be talking about different species of sailfish. Better safe than sorry; assume sailfish aren't kosher unless you can inspect the scales for yourself.
Some examples of fish that have single fins are: Orca, White shark, Indo-pacific sailfish, common dragonet, whales, porposies, cetacenas, ichthyosaurs.
Dorsal fin
Sailfish lay at least 200 young.
The sailfish enemies are the Mako Shark being the main threat, many other sharks, and the marlin.
Both the Marlin and the Sailfish have a spined "fan" as their dorsal fin. The marlin's fin starts with a pointed ridge, then drops off as it travels toward the tail of the fish. (The fin resembles a Nike "swoosh") The sailfish's fin, on the other hand, has a high ridge in the MIDDLE of the fin, like a hump. If you were to use the fins to sail with, that of the sailfish would work much better, given the greater surface area. By the way, you didn't ask, but a swordfish has a pointed bill, but it has no "fan" on its dorsal fin. Hope this helps.
