the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.  

barometer is an instrument used to measure the atmosphere's pressure. the high air pressure relative to average levels is associated with calm and sunny weather. on the other hand, low pressure is associated with bad weather, high winds, and rain.
