Sandy Habitats By: Kevin Sheppard, Richard Morgan, and Emma Murray

Presentation Goals

  • To inform people about the characteristics of different sandy habitats
  • to give a realistic idea about how sandy habitats work
  • To show how habitats change as they move farther from the ocean

Sandy Seafloor

Top Right- This pictures shows a fish in a reef. This shows how the sandy seafloor is not always just sand. Different plants colonize there and help provide a better habitat for fish.

Bottom Right- This pictures shows a sea cucumber. They are an example of epifauna that lives on sandy seafloors. Sea cucumbers are one of the many strange creatures that can be found living in sandy sea floors. It shows how sea floors can host a variety of creatures.

Top Left- This picture shows a bunch of star fish. They can be very common is some areas of the sandy seafloor. They tend to clean up any dead organisms on the seafloor as they invert their stomachs, digest them, then take in the nutrients.

Bottom Left- The picture shows a ray. One of the predators that live on the sandy sea floor. It shows how the organisms can vary in size in the same or similar habitat.

Big Picture-This picture shows a relatively empty looking sandy sea floor. It is not as empty as it looks though. Infauna lives underneath the surface. Plants also tend to live on the sandy seafloors, although they are not in this picture

Sandy Beach

Sandy Beach

Seagull- This is a seagull. It is an example of a bird species that is normally found around the beach. They are able to feed on things found this area like invertebrates, and sometimes fish. They also tend to eat foods left on the beach by humans.This is a picture of a lobster band that likely was once on a trap. It is an example of the marine debris that may be found on the beach. Beaches are sometimes litter in marine debris from humans. This can have a negative impact on the organisms that live there as they may ingest it.This is an empty clam shell that was found. It is another of organisms that live on the beach, although nothing currently lives in this shell. Crabs and other mussels can be found in the sand if you dig for them.This is a picture of the waves coming in with a dead leaf. It shows how there are some plants found on or near the beach and it is not all just sand.,This pictures shows the waves coming. These waves can reach different points on the beach depending on if it’s high or low tide. This can affect the organisms living there and creatures need to be adapt to live there. It also gives more of an overview of how the beach we visited were was. Since the beach is flatter and next to the ocean it tends to be windy. This helps the beach continuously change, as all sandy habitats do.

Sand Dunes

Sand Dunes

Sand Dune- A sandy dune could be described as a type of environment in which many species call home. It is a tall structure made naturally by wind out of sand. It forms and moves shape constantly, and is a key environment throughout the world. They are a vital thing for oceans, and for habitats. In the first slide, you will see that this type of landscape has many different sights. Some with trees, some with small plants, some steep, some level to walking areas.

Salt Marsh

Salt Marsh

Salt Marsh- These areas are shallow pools with a large variety of life and very high salinity. Each picture shows different views of the small salt marshes we saw on our trip. 2 of the pictures showing houses along the marsh showing that humans have an influence on the ecosystem. You can see the different species of algae that grow in the marsh’s water.

Top Right- This picture includes the marsh, the plants that live in it, and the houses surrounding it. Bottom Right- This picture demonstrates an overview of the marsh including all the reeds growing in the pond. Top Left- This picture is just a view of the marsh and all of the small areas of land around it. Bottom Left- This picture shows a different angle of the marsh as well as homes that are meant to show human influence on the land.
