What causes this merger's unique appearance?

What kinds of galaxies are merging in this image? Are the bright spots just artifacts, or do they indicate star forming regions (or something else)? Are the spots to the lower right debris or just foreground/background objects? Thanks for the help.

Hi A002615 and welcome to the Zoo
Both galaxies are seriously disturbed but I think it is two spirals merging.The bright blue/green spots are aareas with very active star formation triggered by the interaction between the two galaxies. The smaller bright spots lower right are conected to this system and are also star forming areas.
Happy hunting ! 😄

This system consists of a pair of galaxies, dubbed IC 694 and NGC
3690, which made a close pass some 700 million years ago. As a result
of this interaction, the system underwent a fierce burst of star
formation. In the last fifteen years or so six supernovae have popped
off in the outer reaches of the galaxy, making this system a
distinguished supernova factory. Arp 299 belongs to the family of
ultraluminous infrared galaxies and is located in the constellation of
Ursa Major, the Great Bear, approximately 150 million light-years
away. It is the 299th galaxy in Arp's Atlas of Peculiar Galaxies.
Despite its enormous amount of absorbing dust, enough violet and
near-ultraviolet light leaks out for it to be number 171 in B.E.
