Identify mystery water creature.

I'm in benidorm and in the pool I just found a strange creature. Its about an inch long, brown on top with a lighter coloured underside, solid body as best I can tell. It has 2 very long "arms", that appear to bend in multiple places. It can swim under water and scull on the surface. It possibly has some sort of camouflage as I was looking right at it and it disappeared.
It has 2 bulging eyes at the front, very close together and when we caught it, it used its arms to jump around.

It seemed to me to be some sort of fish but I don't know how it got in the pool unless it came from the sea on someone's clothes (a few of us went sea kayaking yesterday)

A water boatman?

I'm assuming you can't/didn't take photos?

I agree with pipeski that the "2 very long arms" and swimming underwater or skulling on the surface sounds like something in the water boatman family (corixidae). Most of them are able to fly (although they don't do it often), so they can easily show up in a pool

Another possibility, if it looked more insect than amphibian, is a Giant Water Bug. These bugs are really big. They are pretty charming, great swimmers and divers. They can take a bubble of air with them and dive under water for a long time, using it like a scuba tank.

Possibly a dragonfly or damselfly larvae?

Or a great diving beetle (as you're in Europe).
