What is the difference between perch scales and shark scales?

Answer 1

Sharks don't have scales, if I remember right. Technically, they aren't true fish because they have cartilage skeletons and are more closely related to manta rays.

Answer 2

Of course there's a difference! Minor keys/melodies sound different than major keys/melodies. The biggest difference is that in F major, F is the tonic; in D minor, D is the tonic. What's the tonic? Well it's sort of the main note. All the other notes want to be the tonic, and everything sort of revolves around the tonic. I can't think of a really good and simple example for a minor key right now, but this should make it clear for you: C major and D Dorian also have the same notes. Play the song "Drunken Sailor" in D (it will start on A). It's a Dorian melody. The last note is D, and it sounds good that way. That's because D is the tonic. The whole melody sort of steers you towards that D at the end, and when you get there, it sounds wonderful. Now play the song "Happy Birthday" in C (it will start on G). Now stop at the second to last note (which will be a D). Are you okay with that? Does the melody sound "complete"? Of course not! It sounds awful. The melody almost demands that it resolve to C, the tonic. The same goes for major/minor, or any mode/scale that uses the same notes as some other scale. It's not just the notes you're using, it's how they're being used.

Answer 3

Regular fish have scales such as your Perch; Sharks do not have scales, their skin is covered with a sand paper like coating which is made up of the same thing as their teeth are made of. Nights of old used shark skin to make the cover on the handles of their swords, this ruff texture gave them a strong gripe even when covered in blood. Shark skin has and still is used as a sand paper for wood working by craftsman's throw out the world. Shark skin can give you a nasty cut, and is not covered with fish slim either.
