Help identifying a type of Maltese Cross

[Caradoc]

I've tried Google under "Dolphin, cross" and "Whale, cross" with no luck. It's kind of a neat pendant and I thought that if there is a story to the design the rabble would know.

You might also look for references to the fylfot in addition to the swastika.

It looks similar to a symbol on a Celtic cross from the Early Middle Ages. I have a replica of it in my kitchen. It's got the four arms that double back on themselves. That one is supposed to represent the sun and the Divine, but your's looks to much like fish for it to be much else, I think.
