Animals that don't swim but scurry, crawl, hop, scoot, burrow or slither across the bottom of a body of water.
Sea animals that stick themselves to one place and don't move such as sponges and corals.
Eat to get food, often eating phytoplankton. Weak swimmers so they drift on the current. The lion's mane jellyfish is an example of a large one.
Animals that clean up the oceans and rivers of the world by eating the microscopic creatures and debris that float about in the water. "Cleaning Crew"
Water that is either moving closer to the shore or farther away. High tide is when the water is closer, low tide is when it is further away.
During a new moon or full moon the high tide is higher than usual and the low tide is lower than usual. Caused by the sun working with the moon to pull on the oceans.
When the sun's gravity works against the moon's gravity causing the high tides to be lower and the low tides to be higher.
