= Eudyptes Chrysolophus =

**Animal Classification**

**Endangered Species Act**
- Year Assessed: 2008 - Justification: The population of the Eudyptes Chrysolophus has declined rapidly over the last 36 years.

**Location of Ecosystem**
- 4 cm and 0.45 cm - Location on Globe: Atlantic-Antarctic; Atlantic-southeast; Atlantic-southwest - Where animal lives in habitat: Polar and Terrestrial habitats

**Physical Habitat Features**
- Currents: Labrador Current, Gulf Stream, North and South Equatorial Current, North Brazil Current, Guinea Current, Angola Current, Brazil Current, Benguela Current, South Atlantic Current. - Temperature: 0 to -2 degrees Celsius - Salinity: 34 PPT

**Migration Patterns**
- Macaroni Penguins range from the sub-Antarctic to the Antarctic Peninsula to breed

**Population Estimates**
- 9,000,000 are alive

**Survival trend of species**
- Population is decreasing

**Appearance of Species**
- Size: About 71 cm - Weight: 5 to 6 kg - Color: Yellow-crested; Black and White penguin; - They have long yellow, orange and black crests that project from the top the head - They are look the same in all external features in both the male and female

**Reproduction**
- Macaroni penguins breed once yearly - Generally the younger females are going to want to mate with the older males. - Usually breed in the sub-Atlantic. - Adult penguins breed in October and lay their eggs in November. - Time to hatching: 33 to 37 days - Two eggs are laid with a period of 4 to 5 days between the the two - Time to independence: 60 to 70 days

**Anatomy**
- Their wings have become flippers which are useless for flying - They are very agile in the water because of their streamlined bodies. - All penguins are countershaded for camouflage - They can drink salt water because of their supraorbital gland. This gland filters excess salt from the bloodstream - Penguins either waddle on their feet or slide on their bellies across the snow. This movement conserves energy while moving quickly. - The bill of penguins who feed on krill, like the Macaroni penguin, are shorter and stouter than penguins that primarily eat fish. - Penguins have an average sense of hearing for birds - Their eyes are adapted for underwater vision. They use their eyes for locating prey and avoiding predators. - Penguins have a thick layer of insulating feathers which keep them warm in the water.

**Food Chain**
- Macaroni penguins mostly eat krill - They also eat some fish and amphipod crustaceans - What eats it: leopard seals and killer whales

**Economic Importance**
- Even though Macaroni penguins represent a large food resource they are insignificant to humans. - The parts of the Macaroni penguins are a source of valuable material. - Ecotourism: There are programs that profit from the appreciation of animals.

**Threats**
- Some reasons for endangerment are commercial fishing, ocean warming and oil pollution. - The biggest threat are humans due to the overfishing of their food.

**Conservation Efforts**
- Long-term monitoring progams are put in breeding colonies
