Where Land Meets the Sea
We have been able to see a large part of the intertidal zone lately, because a full moon happened recently. Near Nanaimo, there has been about a 12 foot 4 meters difference between low and high tide.
This zone will decrease by a little bit tomorrow and even more the next day. Why am I giving you all this information about tides? Well, this motion of the ocean up and down a beach creates different zones, where certain plants and animals to live.

In other words, there are four zones within the intertidal zone. By understanding a bit about these parts of the intertidal zone, you can learn what types of plants and animals prefer to live there. The spray or splash zone is the very upper part of a beach that occasionally gets splashed, but never gets covered by the ocean.Where The Atlantic Ocean And The Caribbean Sea Meet Is Stunningly Breathtaking
Plants and animals that live here are very well adapted to living exposed to the air, sun, rain, and even frost. We have found one plant in this zone: A mollusc we found living in this area is the Fingered Limpet. The upper intertidal zone is the upper part of the beach that gets covered by high tide.
Plants and animals that live here are underwater for a little while, but mostly they are used to living above the water surface. Plants we have seen living here are little rockweed and sea lettuce. These animals can actually survive at lower zones too. The middle intertidal zone is covered by water half of the time. More plants and animals live here, because they are not exposed to drying conditions for too long.
The lower intertidal zone is the lowest part of the beach. It is only exposed to air for a short period of time at low tide.

There is a lot of life here! This predictable pattern has gotten them into trouble. Jean-Michel Cousteau and the team explore mangroves forests to learn more about their vital role in keeping our oceans, and people, healthy. Once listed as critically endangered, goliath groupers have been rebounding in recent years due to increased protection over the last two decades. They are immensely important habitat for juvenile fishes.
As researchers learn more about the life cycle of groupers and other fishes, they are realizing the various life stages and the importance of particular habitats, like mangroves, in supporting new generations of fishes.
Because of the intricate branches and roots, mangroves provide the perfect sanctuary for young fishes and invertebrates like crabs and shrimps.
Here, they are safe from bigger predators, and can hide and hunt among the complex branching structures of the mangrove roots. For Goliath groupers, juveniles will spend the first five to six years of their lives living among these tangled undersea nurseries. In South Florida alone, it is estimated that up to 90 percent of commercially valuable sea life depends on the mangrove forests for some stage of their life cycle.
Along the edge of the sea, they can form dense aggregations, turning shorelines into forests. To survive this harsh environment, mangroves have special adaptations, including filtration systems that keep salt out and complex roots that anchor mangroves upright in shifting sediments.

Their complex root structures help trap and recycle nutrients, as well as filter toxins from the water. Particularly important for us, mangrove forests are responsible for keeping our shorelines intact.
They act as buffers, protecting the coastline from erosion due to major storms and hurricanes. And up in the treetops, mangroves provide nesting grounds for hundreds of bird species like brown pelicans, magnificent frigate birds and roseate spoonbills. Without the mangroves, coastlines erode, birds leave, juvenile fish loose their nursery home, and the link between open sea and coastal realm is lost.
Disappearing mangroves around the world In the Florida Keys, as much as 60 percent of shallow mangrove forests have disappeared from coastlines. Worldwide, the declining trend is alarming. The greatest threats come from unsustainable development and land clearing for commercial enterprise or agricultural use.
As global tourism increases, the demand for coastal development is likely to rise. However, great progress can be made if visitors understand the value of mangroves, and choose travel destinations that conserve and protect mangroves and the rich ecosystems they support. One of the larger fishes in the sea, Goliath groupers, spend the first five to six years of their lives in the sheltered branching roots of the mangroves.
The relationship between mangroves and the ocean is interconnected within the larger complex oceanic system. It amazes me to know that one of the bigger fish we find in the sea, the magnificent Goliath grouper, first begins its juvenile life swimming around the dangling branches of the mangroves, seeking shelter in the nursery grounds of nature.
