Rockhopper Penguin (Eudyptes chrysocome)
The Southern Rockhopper Penguin (Eudyptes chrysocome chrysocome) is the smallest of the crested penguins and breeds on the Falkland Islands, southern Chile and southern Argentina. They get their name from the ability to "hop" from rock to rock with the ability to hop up to 6ft (2m) looking for a breeding spot. They have black bodies and flippers, white bellies and a thin yellow crest, called a supercilium, that extends behind their red eyes. They can dive up to 328ft (100m) for several minutes while on the hunt for food and will often stay out in the ocean for days at a time, sleeping while floating on the sea. Penguins have the highest number of feathers of any bird, with more than 100 feathers per square inch which help them swim fast, swimming up to 7km per hour. This is fast enough to launch them out of the water and onto the land. Since penguins spend approximately 75% of their time underwater but also need to see on land, they have a nictitating membrane that acts like a third eyelid and creates a protective barrier when swimming. They also have a supraorbital gland near their eyes that filters salt water out of their system, mixes it with moisture inside their gland and excretes it out of their nose allowing penguins to regulate the salt in their body that they absorb through the water and through the fish they eat.
Clown Triggerfish (Balistoides conspicillum)
The Clown Triggerfish (Balistoides conspicillum) is a benthopelagic (fish which can float in the water column just above the sea floor), demersal (live and feed on or near the bottom of the sea or lake) fish that lives near coral reefs in warm parts of the Pacific and Indian Oceans. They get their name from two things. They have bright orange lips that look like a clown, and they have two spines on the dorsal fins (on their back) that trigger when the smaller fin is pressed onto the larger one. This trigger effect is used for defense from predators and wedging or anchoring themselves into holes or crevices in the coral. When the smaller, posterior spine is pressed on the larger one it disengages allowing the spines to relax and fall back to the body so the fish can remove themselves from their coral nook. They also have strong jaws that allow them to crush and eat sea urchins and shelled prey like clams, crabs, snails and shrimp. To uncover hidden prey they blow jets of water out of its mouth towards the sand. They have teeth that never stop growing which allow them to maintain a diet or sea urchins and coral. They have eight sharp teeth in the front of their mouth, six teeth behind those and molar-like grinding teeth in the throat.
Pinktail Triggerfish (Melichthys vidua)
