What is the difference between a wetsuit and a drysuit?
in one of the them you are wet and in the other one you are dry
honest... it's that simple. a wetsuit is (usually) made of neoprene and allows a limited amount of water into the suit. that is why you want a good fitting wetsuit, because you do NOT want a lot of water moving in and out of the suit, just a little. this small amount of water (debateably) warms up and helps the insulation properties of the wetsuit
a drysuit is just that. you are COMPLETELY dry for the duration of your dive. it is therefor also much more complex in construction to complete this herculean task of keeping all water out of the suit from neck seals, to arm seals and such.
ps: it is easy to weeWee in wetsuit, you need to have all kinds of special apparatus to weeWee in a drysuit.
It's important to understand that there is a difference between wetsuits made for swimming, like triathlon wetsuits, and those made for other purposes, like scuba diving and surfing. Triathlon wetsuits allow the shoulders to move freely, facilitating the swim stroke, and are thinner than other types to stay within rules for the amount of buoyancy they provide.
Has anyone used a triathlon wetsuit for surfing In other words is the tri wetsuit felxible enough to use as a surfing wetsuit?

The wetsuit is made out of closed-cell foam neoprene rubber. That makes it difficult for water to flow in and out of a properly fitted wetsuit except for through the zipper, neck opening and cuffs. Once the cold water enters the wetsuit, your body heats it up. The foam serves to insulate that warm water and that warm water stays warm.
Believe it or not, there are several alternatives. In a wet suit ... just do it. If you are in a dry suit, then you can wear adult diapers ... or if you are a male, you can add a "p-valve" which utilizes an external catheter (i.e. condom type) that attaches to a tube that is attached to the drysuit so a male diver can relieve himself outside the drysuit now.
Everything has a minimum temperature including all swimming pools. If you mean minimum usable temperature, that would depend entirely on the person using the pool. Most people think 68 degree water temp is too cold to swim in, but I have gone swimming in outdoor pools with water temp in the mid 30's to patch holes in the pool liner. And NO, I didn't have a drysuit or wetsuit available to use on that job…
A bathing suit for starters, a rash guard, or most surfers wear nothing under. A common additional item to wear under a wetsuit is a one piece lycra suit. The benefits of this are that it makes the wetsuit easier to put on and off, and the lycra doesn't compress. For instance someone diving a 5mm farmer john (2 piece) wetsuit and a 2mm lycra dives deep enough that the wetsuit has compressed to half…
I would suggest NOT wearing your swimsuit on under your wetsuit. It will bunch up and leave you in a world of discomfort. Instead wear a spandex like short under your wetsuit - i prefer Helo shorts (it's a brand). Then wear your boardshorts on OVER your actual suit. At least that's how we do it when Kiteboarding in MI.
The use of a wetsuit helps reduce the onset of hypothermia but does not prevent it entirely. In very cold ocean waters (Alaska, BC, Washington State) a wetsuit can help a swimmer stay alive for hours especially if properly equipped with booties and a cap. In warmer waters (California, Mexico, Australia) the wetsuit will prevent hypothermia but will not help with the degradation of the skin in salt water. A person can live for days…
This all depends on the way you are going to use the wetsuit. The cooler the water you will be in, the thicker your wetsuit should be. However, with thickness comes a loss of mobility. If the water isn't too cold, and mobility is a major concern, a springsuit would be a good choice (shorter legs/sleeves). But if the water is frigid a fullsuit would be the better choice.
