Can speed practice alone help long distance endurance?

If I only practice to improve the speed in short distance, will it help increase the endurance needed for long distance? ~ ~ ~> probably not, there's a lot of variables to address, how much training have you done recently? how much training you did when you were at your peak? how many years of training did you do at your peak? how old are you? how many years did you not train & how out of shape did you get during your break? you'd need to get into the specifics of exactly what sort of training have you been doing and what do you consider long distance my answer to improving your swimming ability is: Tip 265 Train harder, smarter, faster, further, more often, with a coach, with a team, in a convenient facility & at a convenient Time Train harder, smarter, faster, further, more often, with a coach, with a team, in a convenient facility & at a convenient Time it's unlikely that you can "train for several months for (only) speed, could I, one day, suddenly find myself swimming long distance without feeling tired?" you need to specifically condition for the events you plan to swim. I always considered myself a sprinter, but I did a lot of middle distance training my jr & sr years in high school and as a masters swimmer I found that the training we do at Longhorn Masters is plenty to prepare for the 400 IM, 500 fr & 1500. I'm fine if I + ramp up my training for several months before the event and + split my swims correctly.
