Currently there are over five thousand active volcanoes underwater varying from ones larger than any on the surface to cones no larger than an automobile.

Underwater volcanoes are called submarine volcanoes. They form in a similar way as their continental counterparts, that is close to plate boundaries.

underwater volcanoes
Volcanoes aren't exactly hidden, but over the years, the sea level gets higher & higher, & some volcanoes go underwater, were we cannot see them at all.
Underwater volcanoes and mountains can form at both convergent and divergent boundaries.
Underwater volcanoes introduce substances into the water that bacteria can feed on. These bacteria are the source of nutrition for miniature ecosystems that emerge around such volcanoes.
No, some volcanoes are underwater and when they erupt the magma gets higher and higher and forms on the ocean which is land. (that is how Hawaii was made)
All volcanoes have some dangers, of course. Some underwater volcanoes can lead to tsunamis or other forms of water disasters. Land volcanoes spit ouot hot ash and lava and molten rock, and smoke as well, so much so that you could be burned alive by boiling hot ash, choked to death by smoke or gas or burned by lava, or even crushed by falling rock.
