What I suspect is that these shapes are an ILLUSTRATOR STYLE... is there an equivalent to "create layers" to turn the style as a regular path?
Shay , you can create dashed lines in Photoshop as well :
check these tutorials :

But beware! he is wrong when he says that shapes cannot follow paths!!!!
EDIT: I AM wrong! the information on the following paragraph was for Photoshop 6.. I did not read it correctly.. sorry Mr Bauer!
Thus, disregard this paragraph :
Remember, however, that these dashes will not follow the paths of the cursor, but instead stay oriented to the page. This figure shows the difference between a dashed line created in Photoshop (top) and one created in Adobe Illustrator (bottom). The Illustrator dashes follow the path no matter how it curves.
In this one, he shows how to make the tip shape follow the path! :
