Heya clamperl does have an evolved form....if you trade it when it's holding either a deepseatooth or a deepseascale. It can evolve into gorbyss or another one...I forgot...Just try out both deepsea things. Oh ya, you can't get both, so you gotta trade.

Hope i helped!

1) Yes Clampearl does evole, I also happen to be able to tell you where I found all my information on the pokemon, their numbers, and if they evole or not(continue to bottom of post)

2)
#91-Bellosom (1foot4inches, 13pounds, ability- Chlorophyll, grass type) (evolves from a Gloom w/ a Sun Stone)

#129-Corphish (2foot,25pounds, ability- Hyper Cutter/Shell Armor, water type)

#130-Crawdaunt(3foot7inches,72pounds, ability-Hyper Cutter/Shell Armor, water-dark type)(evoles from a Corphish, I forget waht level, I think around 30 something, if not 40 something, but not sure)

#151-Chimecho (2foot, 2 pounds, ability-Levitate, psychic type)(I think that you have to look around the orbs on top of Mt. Pyre, could be someother pokemon I'm thinking of if not there, I think you have to trade it from Pokemon Colloseum(spelling?)- good luck)

#177-Huntail (5foot7inches, 60pounds, ability-SwiftSwim, water type)(evolves from trading Clampearl w/ a deepseatooth)

***Clampearl is found on sea floor***

#178-Gorebyss(5foot 11inches,50pounds,ability-SwiftSwim, water type)(evolves from trading Clampearl w/ Deepseascale)

#180-Corsola (2foot, 11 pounds, ability-Hustle/Natural Cure, water-rock type)(I found it in water by the waterfall near Evergrande, but I think I've heard that it's found near 128 or something like that)

#199-Groudon (11foot6inches, 2,095pounds, ability-Drought, ground type) (only in Ruby game-unless you trade it-found in Cave of Origin (or something like that) anyways, where you found Kyogre)

In case you were wondering,
# 201-Jirachi(1 foot,2pounds, ability-Serene Grace, steel-psychic type) (don't know where to find it, if anyone knows, PLEASE help me out on this one.)

Then all your rare ones,

#198-Kyogre(14' 9", 776lbs, ability-Drizzle, water type)

#197-Latios (6' 7",132lbs, ability-Levitate, dragon-psychic type)

#196-Latias (4' 7", 88lbs, ability-Levitate, dragon-psychic type)

If you need anymore information like this ask about the # or Pokemon name, I'll give you as much as I can, even though my Pokedex only has like 87 or so hehehe. (147 or so seen :P) You can also ask for GrimCheatJr's help with that in question.

1. Get your Scanner and give it to Captain Stern in the Slateport terminal. He will offer you a choice of Deepseascale or Deepseatooth. Attach Deepseatooth to Clamperl and trade it and you get Huntail. Attach Deepseascale and trade it, instant Gorebyss.

2. Here's your list:
91. Bellossom: Evolve Gloom with Sun Stone
129. Corphish: Fish on Route 102 or in Petalburg City
130. Crawdaunt: Evolve Corphish at level 30
151. Chimecho: Mt. Pyre, high summit
177. Huntail: See above
178. Gorebyss: See above
180. Corsola: Fish on Route 128 or in Evergrande City, Pokémon Center area
199. Groudon: Do on Ruby what you would do on Sapphire to get Kyogre

To evolve clampearl just give it a deepseascale or tooth and trade it. Voila. Either huntail or gorebyss is now yours. Note: Scale= Gorebyss and tooth=Huntail.
