Rocky Shore Info
http://www.ypte.org.uk/environmental/seashore-a-rocky-seashore-ecosystem/98
Seashore life occurs in zones on the shore, according to how tolerant different species are of exposure to air and sunlight. Above the level of the highest tides is the splash zone, strongly affected by salt spray. The upper shore is not covered by every high tide, usually only those of spring tides. Very few species can tolerate the relatively dry conditions of the upper shore. Most seashore animals and plants live in the middle shore, the main area of the shore which is covered and uncovered by every tide. The lower shore is only exposed during the low tides of spring tides, and this is where many delicate species may be found – those that cannot withstand much exposure.
The seaweeds of a rocky shore grow in different areas – zones – depending on their ability out of the water. The animals show a similar zonation, but because they can move around it is not so obvious. Like the plants, the animals are greatly influenced by the tide. Some species live almost as land animals around the high water-mark of spring tides, and others are only briefly exposed to the open air at the low water-mark of spring tides.

Marine Birds
I chose to do marine birds as my organisms because they can be found feeding off of other organisms that inhabit rocky shores. Marine birds don't get wet when they enter the water. They have a preening gland which secretes waxes and fats over the feathers to "waterproof" the bird. They also have salt glands in their body. This allows them to drink salt water, and sneeze the salt of out the water so it doesn't go into their body.

Sea urchin
The animal which I will be covering is the sea urchin. Here is some information which will allow you to better understand the sea urchin.
| Diet | seaweed, algae and bits of plants and animals |
| Size | up to 4 inches ( 10 cm) |
| Color | purple and light pink |
| Life Cycle | |
| Predators | Who wants to eat a pincushion? |
| Neat Facts | They have five teeth. |
| Types | Caribbean sea urchin, pencil urchin, Slate pencil urchin, purple sea urchin and sea potato |
| Relatives | star fish and sea cucumber |
I want to begin by apologizing by taking so long to get this post up. I have been dealing with a lot of things throughout my life. But I have it all under control now and am good to go.
I am in the Rocky Shore Group and will be focusing on the Non-Vertebrates. I am very excited for this topic and will be posting some interesting information about this topic. Stay tuned for more.
