Salt Marsh

Grade 4 Salt Marsh

Nursery The salt marsh provides protection for baby animals from predators.
Filter Removes small harmful materials and makes the water clean.
House Provides shelter for many animals so they can hide from predators.
Rest Stop or Pillow Important resting and feeding stops for migrating birds.
Sponge Absorbs excess water during heavy rains, high tides, and floods
Grocery Store Provides food for animals.
Adaptation A change or adjustment that an organism makes over time to help it survive in its environment.
Physical Adpatations Part of the organism’s body and help it meet the challenges of living in its habitat. Examples: Webbed feet for swimming, sharp claws, long legs for hunting in deep water, extra eyes to spot food or predators.
Behavioral Adaptation Things an organism does to survive in its habitat. Examples: hibernating and migrating in winter; periwinkle snails climbing up the grass to escape high tide; a muskrat building a lodge for shelter.
Tidal Channel Changing tides - floods and empties twice a day. Animals need to adapt to wet and dry conditions. Provides habitat for fish, like mummichogs, shrimp, and crabs.
Mudflats Changing tides - floods and empties twice a day. Animals need to adapt to wet and dry conditions. The mud can be hard to move through. Low tide allows land animals and birds to find prey or food.
Low Marsh The salty water and daily flooding make it hard for plants to grow. The tall cord grass provides small fish a place to hide from predators.
High Marsh Floods during really high tides. Lots of salt in the water makes it hard for plants to grow. Salt marsh hay provides protection for coffee bean snails and mussels. Good place for nesting.
Uplands Less salinity means there is more plant competition. Provides habitat for birds.
Tides The salt marsh is flooded twice daily. Water levels vary. The water can be very salty. The tides bring fish and other organisms into the marsh providing food.
