They didn't. The two forces both operate under the Department of the Navy and have a close relationship. Marine forces often provide security on Navy ships, and many Navy ships have Marine units stationed on them (including an air wing) on a semi-permanent basis. Certain "Behind the Scenes" jobs, such as chaplains or medics, are filled in the Marine Corps ranks by Navy personnel because the Marines don't train those positions. These personnel wear Marine uniforms with Navy insignias. Marine officers are trained at the Naval Academy, and Navy officer training includes some training by a Marine Corps drill instructor.
No, you are not. The Navy and the Marines are two separate services. But the Marines are a part of the Navy. Some Navy personnel are assigned to the Marine Corps, such as Corpsman.
No, Marines are not considered part of the Navy. While they fall under the Department of the Navy and share some administrative functions, the Marine Corps is a separate branch of the military with its own unique missions, capabilities, and command structure.

Marines are typically linked to the Navy - often as a separate force within the bureau responsible for the maintenance of the Navy, but sometimes as an actual part of the Navy itself. The term 'Marines' isn't exclusive to that type of infantry - just as frequently around the world, they can be found with the designation of 'naval infantry' or similar.
None. Navy Seals are all Navy. Marines are a completely different branch of military.
The Esperanto word for navy is mararmeo but there is no word for marines in Esperanto.
This may come as a shock to you, but the US Navy SEALs are under the Navy and not the Marine Corps
The United States Marine Corps and the United States Navy are two separate armed services, but both fall under the Department of the Navy, making them part of the same military branch. The Marine Corps is a separate branch of the military, but it operates under the administration and support of the Navy.
The motto of Spanish Navy Marines is 'Per Terra et Mare'.
The Navy
You let your enlistment with the Navy expire and then join the Marines. There is no 'transfer' between the two units. If you are a Corpsman, you can be asked to serve with the Marines.
