sorry if you don't under stand my answer (i don't remember any of the towns names.)but you know town that has the museum( i think it is slateport but i am not sure)? go to the top right corner of that town. inside the building where the ship is. he will let you chose from two items that let you evolve clampearl. but you have to trade clampearl while holding that item. to get clampearl you need to get dive and dive under the water and look in the grass. and you got yourself a clampearl. well good luck sorry if that's not the town but i am sure it is. the boat is supposed to take you to lilycove (i think that's the name)
With the deep sea tooth or scales that you traded it for you give it to a clampearl to hold (The clam pokemon). Then you trade it, depending on what you traded the scanner for you will either get a Huntail or Gorebyss. Hope this helps.
Capt. Stern is not in Pokemon Leaf Green. He is only in Pokemon Ruby, Saphire or Emerald.
You can't use it for much, but you can exchange it for either a deepseatooth, or a deepseascale. The deepseatooth raises Clamperl's Sp. Atk, and the deepseascale evolves Clampearl into huntail. To exchange the scanner bring it to Capt. Stern in Slateport at the Slateport Harbor.
It is only obtainable in Ruby, Sapphire, or Emerald by giving Capt. Stern the scanner in the harbor at Slateport. You obtain the scanner by finding it in the abandoned ship. In Diamond and Pearl, you can also find the DeepSea items on wild Pokemon. Wild Chinchou, Lantern, and Relicanth may hold a DeepSeaScale, and Carvahna and Sharpedo may hold a DeepSeaTooth. There is a 5% chance that one of these wild Pokemon may be holding those items.
when you want to give him the scanner he is in the harbor house in slateport.he will give you a deepsea tooth that raises a clamperl's sp attack or a deepsea something i forgot but it raises a clamperl's sp def. your chooce.
Give it to capt. Stern in Slateport city. the boat house northeast of the Pokemon center.
That's how you get the items in the first place by giving capt stern the scanner.
The Deepseatooth is an item that you receive from Capt. Stern when you trade for the Scanner. If you give it to Clamperl to hold while trading, it will evolve into Huntail.

You have to beat Norman at the Petalburg Gym and the twins at Lilycove Gym to get HM's Surf and Dive. Then, go to the Abandoned Ship (you will see the ship when you ride from Dewford to Slateport on Capt. Briney's ship) and find the scanner. Then, show the scientist on the ship that you have the scanner and he will ask you to deliver it to Capt. Stern who is at the harbor in Slateport. Give him the scanner and in return he will give you either the deepseatooth or deepseascale (which ever you choose).
Near the SS Tidal in Slateport City.
In Slateport city harbour you will see capt. stern being interviewed with a large crowd talk to capt. stern and you will go into the harbour thing and then go to their hideout in lilycove city.
Clampearl doesn't evolve by leveling up. Clampearl can either evolve into Huntail or Gorebyss. To get Huntail, you have to choose to receive the Deepseatooth from Capt. Stern in exchange for the Scanner and then have Clampearl hold it while trading. To get Gorebyss, you have to choose to receive the Deepseascale from Capt. Stern and then have Clampearl hold it while trading. You have to choose one or the other. You cannot choose both.
