i do not know how to get deep sea scale but if you catch a carvanha in D/P or platinum there is a 5% Chance of getting a deep sea tooth
You can find the Deep Sea Scale and the Deep Sea Tooth on Routes 13 and 17.
it does not evolve at any level. to evolve it, trade it while its holding a deep sea scale or a deep sea tooth
You get it when you find the scanner on the abandoned ship and he will trade you a deep sea scale or a deep sea tooth the scale evolves clampearl or seadra into kingdra or gorebis via trade and the tooth evolves clampearl into huntail
When you trade Clamperl with the deep sea scale you get Gorebyss with the deep sea tooth you get Huntail.
You can't find this item to get it receive the scanner in the abandoned ship and give to capt stern he will let you have deep sea scale or deep sea tooth pick the tooth.
random clamperl held item
You can find a deep sea scale in Slateport City, Captain Stern will give it to you after you give him the Scanner which you can find on the Abandoned Ship.
In the third generation of Pokemon games, a Deep Sea Scale will help Clamperl evolve into Gorebyss when traded. After giving the Scanner to Captain Stern in Slateport Harbor, he will offer the player a Deep Sea Scale.
The Deep Sea Tooth and the Deep Sea Scale are both used to evolve Clamperl into either a) Huntail or b) Gorebyss. - Badminton
Trade a Clamperl to any random person. Note: It needs to hold Deep Sea Scale while trading. I'm not sure where you can get Deep Sea Scale in any game so try hard to find it.
If you want a deep sea scale then you have to catch a wild relicanth and hope it has one. If you want a deep sea tooth then you have to catch a wild carvanha. An easier way would just be to get a bannete and use frisk instead of catching everything you see!
