hello, only this photo has it. i don't know what is that. i never saw anything like that and other photos from the same film look completely normal.

'Crowsfoot' marks like that are typical of static discharge. It usually occurs if film has been advanced rapidly for several frames, and is more prevalent in cold and low-humidity weather conditions.

Nylon cassette light traps and all-plastic cassettes will also provoke it, as will rapidly loading film from a bulk loader. There's no telling where the static fogging occurred. It might have been during cassette spooling, in the camera, during rewind or in loading the processing spiral.

Some people go a lifetime and never see it. I've seen it only on two occasions in real life, and a few times heard 2nd hand accounts and seen examples.

There was a superb example shown on the questionable TV series "NASAs Unexplained Files" where it was mooted to be evidence of a 'space jellyfish'! There was a muttered alternative of electrostatic interaction with the film, but obviously that isn't half as mysterious as the existence of space jellyfish.

thank you, so that is electricity.

the film is not hand rolled, it is tri-x rolled by kodak.

the camera is nikon n2000, it advances the film itself with the motor. may be that was too fast.

or the combination of several circumstances. anyway i know whats that now. (:
