![]() Many lagoons do not include "lagoon" in their common names. When used within the context of a distinctive portion of coral reef ecosystems, the term "lagoon" is synonymous with the term "back reef" or "backreef", which is more commonly used by coral reef scientists to refer to the same area. Coastal lagoons are classified as inland bodies of water. Kusky characterizes lagoons as normally being elongated parallel to the coast, while estuaries are usually drowned river valleys, elongated perpendicular to the coast. Davis does state that the terms "lagoon" and "estuary" are "often loosely applied, even in scientific literature". restricts "lagoon" to bodies of water with little or no fresh water inflow, and little or no tidal flow, and calls any bay that receives a regular flow of fresh water an "estuary". The distinction between "lagoon" and "estuary" also varies between authorities. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Lagoons are common coastal features around many parts of the world. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. They have also been identified as occurring on mixed-sand and gravel coastlines. Lagoons are commonly divided into coastal lagoons (or barrier lagoons) and atoll lagoons. Garabogazköl lagoon in Turkmenistan Venetian LagoonĪ lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. The shallow lagoon is separated from the Mediterranean Sea by narrow shoals connecting to a small, rocky mountain. ![]() Balos coastal lagoon of northwestern Crete.

If removed from their home area, they are able to return to the area using their highly developed sense of smell. Tidepool sculpins have a keen sense of smell. If disturbed, they quickly propel forward with a snap of their tail to another hiding place. Tide pool crowding may affect their growth rate. After thirty to sixty days, they move back into rock pools and become juvenile fish. No further egg guarding or parenting is done. Females typically lay several batches of eggs each year. Fertilization doesn’t take place until the eggs are laid in seawater. The males use their pectoral fins to hold the female while fertilizing the eggs as she is depositing them on a surface. Tidepool sculpins mature in approximately one year. ![]() These fish feed on small invertebrates such as worms and small crustaceans. Tidepool sculpins may grow to a maximum length of 3.5 inches (9 cm). They are able to tolerate warmer water or water with lower salinity. They are able to change color to camouflage themselves. Tidepool sculpins are splotchy, with colors varying from brown, grey, and white to possibly greenish or reddish and dark splotches on their back. It also has small tendril-like appendages called cirri on top of the head. It is not as heavily spined as other sculpin species, with only a single spine on its jaw. This small fish has a large head, tapering body, and large dorsal and anal fins. They are able to tolerate both brackish and normal ocean water. This intertidal temperate water species lives in sheltered areas and is typically found in tidepools. Tidepool sculpins are found in the North Pacific Ocean, from the Sea of Okhotsk and Bering Sea down the west coast of the United States to Los Angeles County, California. Tidepool sculpins are on view in the oyster exhibit in Pacific Visions culmination gallery on the second floor.
