Scientific Name: Morone americana
Description: silver toned scales, small head, 6 fins total, 2 beady black eyes, with the size varying from 8-10 in.
Food Source: Mainly eats fish eggs. Also, Mud and Fathead minnows.
Habitat: the Atlantic coast, often in the chesapeake bay, lake Erie, and Ontario.
Niche: they both benefit their ecosystems by serving as predators and prey.
Migration: As they grow, they migrate downstream to brackish waters.
Competition/Cooperation: Fights Yellow perch for zoo plankton. Cooperates with bass to eat Fathead minnows
Challenges: -a parasite called "Lironeca Ovalis" is sometimes found in the gills.
-predators: striped bass, bluefish, and walleye as adults, and bluegills and copepods when they are still eggs.
Symbiotic relationships: Bass tapeworms have a parasitism relationship.
Importance: As a carnivore, it's consumption of many organisms helps maintain the balance of existing animals in its ecosystem.
Interesting facts: -not an actual - perch, but a member of the bass family. 
-People fish white perch for fun and to eat
Average life expectancy is 17 years
-it's diet of fish eggs extends to cannibalizing it's own eggs.

Importance:the gras shrimp provides food for other animals and it eats algae and dead or/and decaying plants which prevents the nitrite keels from getting to high
Interesting Facts:

Scientific Name: Carcharhinus plumbeus
Description: Has a big dorsal fin and has tan-ish skin. It has a skinny/slim body and a long tail.
Food Source: Eats small fish like menhaden and crustaceans like crabs.
Habitat: Lives in the Western North Atlantic and the Chesapeake and Delaware bays are both nursing grounds for them as well.
Migration: They migrate to subtropical waters when it gets too cold.
Niche: It preys on smaller fish and squid.
Competition/Cooperation:
Sandbar sharks cooperate with remoras and pilot fish.
Challenges: Some main problems sandbar sharks face, is over fishing and pollution.
Symbiotic relationships: Commensalism because remoras gets transportation and shark gets clean.
Importance: Keep the population of smaller fish and squid steady.
Interesting Facts: Most common shark found in the Chesapeake Bay.  

Migration: Striped bass migrate to the Chesapeake Bay
Role in community:
pelagic predator
-roam in open water and eat small fish
-Top predator
Competition/Cooperation:
Challenges:
-diseases
-lack of prey
-poor water quality
-Big water temperature change in small period of time
symbiotic relation
-parasitism
Importance:
Certain types of organisms will overpopulate and then the ecosystem will lose its balance

Gender is told through having a "T" on there bellies (male). Female crabs can only mate once. The average lifetime of a Blue Crab is three years.

Critter's Common
 Name: Zooplankton Copepods

Scientific Name: Doridicola agilis
Description:Copepods are cylindrical bodies with multiple segments, for example they have 9 trunk segments. Unlike his body it's head is bear prominent and round! Along with it’s head, this creature has 2 LONG antenna’s that is usually longer than their body. These organisms are 1-5 mm long though some might grow about too 10mm. 

Food Source: Photoplankton, Detritus and smaller zooplankton
Niche: Copepods are used as  the basis of our large stocks of herring and mackerel. They're also sometimes used to be our biodiversity indicator.

Migration: they do not migrate but they live in  freshwater like the Great Lakes and etc.
Competition/Cooperation:
Challenges: Some predator are  dragonet, banded killifish, whales, seabirds, Alaska pollock, and other krill. With all their predator they can sometimes harm its health when they eat too much of the Doridicola agili. Along with not eating a lot of these organisms they aren't usually found in population. With all of this you might think that are they over populate or are they endanger well……...They are not in endangered although they get eaten in 2,200-5,500 pounds. 

Symbiotic relationships: Copepods do have a Symbiotic relationship with sharks. They are in a relationship because when the copepods are ingest they then can feed on the shark which as an effect the shark will slowly die but is good for the copepods. 

Food Source: They eat bay grasses like Pond weeds and wild celery and insects like mollusks and crustaceans. They also dive to find prey
Habitat: The ruddy duck lives in shallow waters in the Chesapeake bay. It also can be found in Tidal Rivers and freshwater ponds and lakes.                     
Niche: They are predator to pondweeds, wild celery, insects, mollusks and crustaceans. Prey to Hawks, Minks, Owls and Red foxes.
Migration: The Ruddy Duck lives in the bay region from autumn through spring and migrates in the summer in the Prairie Pothole region of North and South Dakota and Southern Canada
Competition/Cooperation: They compete with other species of ducks and geese
Challenges: It can be infected by a disease call Salt Toxicosis, this can be a very harmful disease. It's other challenges are it's attempt to survive against the duck's predators.
Symbiotic Relationship: The Ruddy Duck has no symbiotic relationships
Importance: Act as predators invertebrates such as chironomid midge larvae and crustaceans. It also eats aquatic vegetation.
Interesting Facts: The Ruddy Ducks are one of the smallest ducks found in the Chesapeake Bay but they lay some of the largest eggs, they are called ruddy ducks because when they swim their tail moves like a rudder to help them be amazing swimmers... but they are very clumsy on land.
