You mean whales with an 'h'- Wales is the name of a country, so your question came up in the 'Wales' category whereas it should have been in 'marine Biology'!
No, they aren't- whales are mammals and have lungs through which they breath, although they can store air in them for very long periods of time- enough to remain underwater for hours, even sleeping there. They refresh their air supply through the blowholes in their backs, from which they vent carbon dioxide and breathe in fresh air.
Sharks are not mammals, but fish- they have no lungs and breathe through gills, which filter out oxygen from the water and mean that they have no need to surface.
Sharks are related to rays and skates, along with other cartilaginous fish.

That's Pacific ocean and YES, there are heaps of them. enough to warant regular air patrols to spot sharks near beaches and other swimming areas.
Fish are a whole sub category including bass and tuna but Wales are actually mamals, and so are dolphins and sharks.
Do you mean are sharks bigger off the Welsh coast? No, not at all, they are the same size as they are anywhere else in the world. Wales has few sharks in it's waters as it's generally too cold for them- the main species it has is the Basking Shark, a harmless plankton-feeder which is not dangerous to humans. Porbeagles have been known to appear from time to time, and on rare occasions tiger sharks, but in the latter case, this is most unusual. The last recorded sighting of a Great White off Wales was in 1976, when a juvenile male got stuck in the Sound of Cardigan Island and had to be rescued. However, that was during an exceptionally hot Summer, when species more used to warmer climes may have been tempted to venture further North due to the warmer seas. But this was a one-off- normally, dangerous sharks don't venture into Welsh waters.
