Narrative:

After a short local flight; I was returning to ZZZ. I was cleared in to d-airspace but tower was busy with several flights and radar was inop adding to stress. After visually locating our flight tower put us on a right base for rwy xx and asked if I could conduct a 'short approach' to rwy xx since there was another aircraft on a 5-mile final. I confirmed that I could make the 'short approach' and proceeded inbound for the 'short approach'. While it is certainly not justification; it is the case that with the hectic action I failed to perform my normal verbal gumps check before landing; and failed to extend the landing gear. The landing was otherwise perfect; on speed; on target; on centerline so the touchdown was very soft. I realized my error when I heard the float's stainless steel skid plate skidding rather than the sound of the wheels. The floats are designed with this stainless steel skid plate for just such an error and performed beautifully. Other than a slight bending of the skid plate; there was no damage to the aircraft or runway; and there was no debris left behind. It's clear I dropped the ball on this landing; and will commit to conducting both a visual confirmation and my verbal gumps check to ensure the landing gear is down and locked prior to landing.

Title: Amphibian aircraft pilot reported landing gear up following distractions on the approach.

Narrative: After a short local flight; I was returning to ZZZ. I was cleared in to D-airspace but Tower was busy with several flights and RADAR was inop adding to stress. After visually locating our flight Tower put us on a Right Base for Rwy XX and asked if I could conduct a 'short approach' to Rwy XX since there was another aircraft on a 5-mile final. I confirmed that I could make the 'short approach' and proceeded inbound for the 'short approach'. While it is certainly not justification; it is the case that with the hectic action I failed to perform my normal verbal GUMPS check before landing; and failed to extend the landing gear. The landing was otherwise perfect; on speed; on target; on centerline so the touchdown was very soft. I realized my error when I heard the float's stainless steel skid plate skidding rather than the sound of the wheels.
