In the spring? Millions of them. "Vernal" pools are low-lying areas that are filled with springtime rain, and which dry up each summer. That's what "vernal" means; springtime.
Tide pools can be the size of a backyard pond to the size of 2 semi trucks! Tide pools have many sizes and many widths.

one year. the vernal equinox is on March 21, or the first day of spring. an equinox is when day and night is equal (12 hours daylight, 12 hours nighttime). there is a Vernal equinox in spring, and an autumnal equinox on the first day of autumn (or fall), September 21.
Tide pools (also tidal pools or rock pools) are rocky pools by oceans that are filled with seawater. Tide pools can either be small and shallow or large and deep. The small ones are usually found far back on the shore and the large ones are found nearer to the ocean. Tide pools are formed as a high tide comes in over a rocky shore. Water fills depressions in the ground, which turn into isolated pools as the tide retreats. This process, repeated twice a day, replenishes the seawater in what otherwise might be a stagnant pool. Many types of organisms live in these pools such as starfish, crabs, and sea urchins.Source: http://www.answers.com/rockpools?gwp=11&ver=2.3.0.609&method=3

Vernal pools support a variety of animal species, including amphibians like salamanders and frogs, invertebrates such as fairy shrimp and water beetles, and birds like red-winged blackbirds and mallards. These species rely on vernal pools for breeding and feeding due to their unique water levels and seasonal nature.
San Diego fairy shrimp are threatened by habitat loss, altered hydrology of their habitat and off-highway vehicle activity. They are listed as Endangered by the US Fish and Wildlife Service. By 1998, their habitat (vernal pools) was reduced to less than five percent of its historical extent (USFWS 1998). Remaining vernal pools are threatened by continuted urban development, increases or decreases in water flow into the pools, and physical destruction of habitat by vehicles. San Diego fairy shrimp occur in vernal pools in mesas from Northern Baja California through Orange County; Most of the historical vernal pool habitat was converted to residential development.
Non vernal
Ok, how many seasonal pools, or disposable pools are sold annually in the US?
There is 1 day for each equinox: the vernal equinox in spring and the winter equinox in winter.
Fairy shrimp live in vernal pools. They are approximately one inch long, and related to lobsters. They swim upside down so they can eat the algae on the water's surface.
