Sea Star Lapbook Information

Here are some sample lessons from the Starfish Lapbook:

Sea Stars Physical Traits (Anatomy)
Sea stars have radial symmetry, which means that their arms radiate (like the sun’s rays) from the central part of the body. They tend to have five arms or multiples of five arms. At the end of each arm is a microscopic eye which allow the sea star to only see light and dark and detect movement.

They also have spines on their skin for protection. Although there are many species of sea stars that don’t really have spines, but have a bumpy texture.

The ventral side has the “mouth” in the center and the tube feet on the arms.

Sea stars have two stomachs: the cardiac stomach and the pyloric stomach. The cardiac stomach can come out of the body and envelope the food. The cardiac stomach begins the digestion process. The food is then transferred to the pyloric stomach to be digested.

The sea star’s tube feet are located on the ventral side. They have two functions. They aid in movement and can be used to open scallops or clams.

Habitat and Diet
Sea stars live in tropical, temperate and polar oceans. They are normally found around rocks and coral, but can be found living in the sand. They can live in tidal pools, rocky shores, sea grass, kelp beds, and coral reefs. Sea stars cannot live in fresh water.

Sea star are omnivores. Their diet tends to be shellfish such as scallops, oysters, clams, or plant material.
