I'm not finding what you are looking for, but my google image skills aren't that great so I will try to explain in a few too many words.
Each type of clef has some sort of centre that defines the note on one particular line. With what you are used to calling a bass clef, it is the : and the line that goes through the middle of the dots is an F, in this case the one below middle C. When you are playing bass this is the F on your D string. To make things slightly more complicated, the bass actually sounds an octave lower than it is written, so "middle C" as a bass player is the first C on your top string, but real middle C is an octave higher than that. It is written this way so all of the low notes we typically play aren't a million ledger lines below the staff.
In the treble clef, the swirl inside the clef is around the G above middle C. With different fonts/writing styles this isn't always as obvious as the bass clef. The alto and tenor clefs are sometimes called "K" clefs because one of the less stylized ways of writing them is basically a K with the middle of the K being middle C.
Those are the 4 most common clefs, and as a bass player you should really be comfortable with the bass, treble, and tenor. Viola is pretty much the only modern western instrument that uses the alto clef, although it is used for viol/gamba music and some unconventional writing styles as well. To be perfectly honest, the majority of the time you will be using the tenor clef is in solo and very rarely orchestral repertoire when the notes are getting into too many ledger lines above the staff for the bass clef. For that reason my reading in the bottom half of the tenor clef is pretty shaky because typically when it gets lower than middle C you go back to bass clef. Treble clef is very useful for reading melodies, lead sheets, and the solo/orchestra stuff that gets up there.
There are different ways to learn what the notes are and what lines and spaces they go on. Starting at the bottom of the bass clef the lines can be remembered as "Good Boys Deserve Fudge Always" and the spaces as "All Cows Eat Grass" with the treble clef being "Every Good Boy Deserves Fudge" for lines and "FACE" for spaces, and I am sure there are some other different sayings that people use. I am pretty sure there are some apps you can get for your phone that give you little exercises for learning them as well.
Hopefully that makes some sense and helps a bit.
If that hurt your brain this is a good place to stop.
If not, each of the three types of clefs above can be classified as F,G, and C clefs. The bass clef is an F clef because the : indicates where the F is, the treble G, and the alto and tenor C. As demonstrated by the alto and tenor clefs being essentially the same clef just moved up or down a line, the same thing can be done with all the other clefs. The most common occurrences of this is the C clefs moving, where the soprano clef is with the middle of the clef (middle C) as the bottom line on the staff, mezzo soprano is the second line from the bottom, alto is the middle line, tenor is the second from the top, and baritone is the top line. Again, you will only really see these in some editions of choir or viol music or the occasional theory exercise, but they are out there. As I mentioned earlier, this is how some people transpose and is helpful for reading orchestra/band scores with parts in different keys for different instruments.
