When the young hatch, they use the quiet waters of the marsh to gain strength before they venture out into the open ocean. Marine Habitat Laguna San Ignacio is one of the few remaining undisturbed marine lagoon habitats in North America. It supports a large number of vertebrate and invertebrate species different from the ones that live in the lagoon's other habitats. Imagine the tides flushing and recharging the lagoon ecosystem. Each rising tide stirs up nutrients from the bottom sediment and recharges areas of stagnant water with oxygen.
Ocean fish ride in with the tide to feed.
Ebb tides flush out dissolved material and carry decaying organic matter as well as living organisms offshore. The marine habitat is home to green sea turtles, bottlenose dolphins, numerous species of fishes, and humans. A small population of Mexican fishing families depends on the lagoon for their livelihood. They fish the lagoon in harmony with nature, and coexist with all the other creatures that call this lagoon home. San Ignacio Lagoon is one of the Earth's true natural wonders.
