Punta Albemarle lies on the very northern tip of Isabela and Cape Marshall (Puerto Egas) on the eastern side of Isabela island. This are rocky volcanic cliffs, that drops down to the ocean floor as an almost vertical wall.

You might see large animals like manta rays, marbled rays, hammerhead sharks and marine turtles, but also Chevron barracuda, snappers, yellow fin tuna, rainbow runners, wahoo and groupers. There are also a lot of smaller fishes like creole fishes, parrotfishes, scrawled filefishes, pacific boxfishes and tiger snake eels.

Interesting are the schools of endemic black striped salemas which are often found here. Salemas belong to the family of grunts. They can join in large, dense aggregations, most often over rocky slopes and protected areas. Other endemic fishes in the Galapagos.

An other endemic fish living here is the white-spotted rock sea bass, a sea bass with a row of white spots on the side. This fish is common here and around Isabela and likes cold water, so it is found mostly in areas of upwelling where it feeds on fish. Length about 25cm.

Another sea bass is the sailfin grouper which is common around the entire archipelago. While it usually is of a gray or brown color, it can also be bright golden yellow. These are known as bacalao rey (king bacalao). This is the economically most important fish in the Galapagos. They prefer open water near walls. Can grow to 1m long.

The Harlequin wrasse or Galapagos hogfish is an interesting looking multicolored wrasse. Not one fish looks like the other, they have various designs of orange, black, white and yellow. Most have a white chin patch and all a black spot at the base of the pectoral fins. Large adults have a distinctive bump on their forehead. They prefer cold water and are thus more common on the western islands. Another hogfish with a distinctive bump is the Mexican hogfish  which has longish fins and is gray to green-blue.

The Zebra moray eel which is uncommon in the entire archipelago is also found here. This moray has an unique black and white color pattern which gives it its name. The snout of the zebra moray is very blunt with pebble-like teeth, so it can feed on large, heavily armored crabs and other crustaceans as well as snails and sea urchins. With the large crabs it will crush the claws and walking legs, with smaller crabs the entire animal. Hunts in reef crevices and rarely ventures out into the open. Length 88cm.
