Fuente: ar.whales.org

The speckled or spotted Pacific dolphin is a slender cetacean of medium size. Its falcate dorsal fin is pointed and very narrow and the pectoral fins are pointed, small and dark on both sides. It has a dark gray mantle, which widens on the flanks in the middle region of the body, to then reduce towards the back, behind the dorsal fin. The sides and belly are lighter gray. As the name implies, the body is covered in spots in varying degrees, according to age and location, there are individuals who in some areas have few or no spots. The coastal subspecies is usually larger, more robust, with a thicker bill and more spots. The lips and tip of the beak are white and a dark band runs from the jaw to the pectoral fin on both sides. The young are born without spots and have a dark gray mantle and very pale sides and belly. The juveniles develop dark spots on the belly and lighter spots on the dorsal region. The number of spots increases with age, getting to merge with each other in older animals. This species can be confused with several other oceanic species of long-beaked dolphins, including the rotary dolphin, bottlenose dolphin and Atlantic spotted dolphin in the areas where the two species overlap. The characteristics that identify the spotted dolphin are its smaller and slender size, the distinctive dorsal mantle and a smaller and narrow dorsal fin.





Frigatebirds

Frigatebirds are seabirds that manage to fly for months without perching and can cover up to 410 kilometers on average every day thanks to their detailed knowledge of atmospheric conditions. In their journey, the frigates need to save as much energy as possible to face such long distances. To do this, they stay at altitudes between 30 and 2,000 meters, a point where they do not need to beat the wings too much, and during the flight they make circular movements to get hooked to the updrafts that originate under the clusters. Each stream is an opportunity to ascend up to 1,600 meters simply by planning and on the ascent they manage to reach vertigo speeds of up to 4 or 5 meters per second.

Flattened fish of the order Myliobatiformes and of the family Mobulidae and as its name suggests, is the largest of the striped species and is closely related to sharks. It is a species that is distinguished by the flat shape of its body and its dimensions. It measures up to 9 meters wide and weighs around 1,350 kilograms. There is little sexual dimorphism although the female is slightly larger than the male. The skeleton of the stingray is composed of cartilage and this allows a great capacity to perform various movements. It has two pectoral fins and a small dorsal fin, as well as a long tail without stings and gills in the lower part of its body. It does not have caudal fins. Two cephalic lobes extend from the frontal area of the head and a row of small teeth is located only in the upper part of the snout.
The skin is rough and scaly and the color of the body varies within the range of dark tones. It is usually black or grayish blue at the top and white with gray "specks" at the bottom.

These turtles belong to the Cholonioidea family and there are currently around 7 living species.

They can live in all the oceans and are characterized because many of them have a large size.

They stand out for their long trips through the gulfs and some like the Laud constitute a great and beautiful spectacle that can be visualized by human beings.
