Olive Ridley Turtle

Olive ridley turtles live globally in the coastal waters of at least 80 countries. Generally, olive ridley turtles are not known to move between or among ocean basins. They may migrate between neritic and oceanic zones near their nesting beaches. Olive ridley turtles are the most abundant sea turtle species largely due to their mass … Read more

Kemp’s Ridley Turtle

Of the six marine turtle species living in U.S. waters, the Kemp’s ridley is the smallest of them all, coming in at under 30 inches on average and weighing about 100 pounds once fully grown. The Kemp’s ridley is also distinguishable by its almost circular carapace, or shell, that is almost as wide as it is long … Read more

Marine Iguana

Marine iguanas are most noted for their ability to feed in shallow, marine waters. They are herbivores and eat marine algae growing along rocky shores and underwater. In the water, they swim with a snake-like motion and hold themselves against the bottom with their long claws in order to graze. Though they feed in the water, marine iguanas are … Read more

Saltwater Crocodile

Though crocodiles and their relatives have a negative reputation among people, most species are relatively harmless and would rather avoid people rather than confront them. The saltwater crocodile, however, is known to show aggression towards people – partly a result of its strong territoriality – and is responsible for at least several dozen attacks on people … Read more

Flatback Turtle

Flatback turtles have the smallest geographic range of all seven marine turtle species, and do not undertake long, open ocean migrations. These turtles are typically found shallow waters less than 60 meters in depth along the coast or continental shelf of Australia. Though this species is known to visit the waters of Papua New Guinea … Read more

Banded Sea Krait

Like the sea turtle, saltwater crocodile, and other reptiles, these snakes must come ashore to nest. They must also occasionally drink freshwater and seek out coastal sources of water for that purpose. Furthermore, they often digest their food and rest on land and use terrestrial rocks to shed their skin. Though they spend much of their time on … Read more

Olive Sea Snake

Growing to lengths over six feet (2 m), this species is well adapted to a life on coral reefs. It has a flattened, paddle-like tail and a large lung that allows it to go hours between breaths at the surface. Given its length, it has special light sensing organs in the tail that allow it to remain … Read more

Leatherback Turtle

Having the widest global distribution of all turtle species, leatherbacks are found in the tropic and temperate waters of the Atlantic, Pacific and Indian Oceans as far north as Alaska and as far south as New Zealand. Unlike many other reptile species, leatherback turtles are able to maintain warm body temperatures in cold water due … Read more

Hawksbill Turtle

Hawksbill turtles are generalist predators that forage on reefs for their favorite food, sponges, as well as a variety of other invertebrates that they find. Some of the sponges and small animals that the hawksbill turtles consume are toxic. Fortunately, their body fat can absorb the toxins without making the turtle ill, but their meat is … Read more

Green Turtle

Similarly to other sea turtles, green turtles are known to travel incredibly long distances during their lifetimes. In some cases, individuals may travel across entire ocean basins from their feeding areas to nesting beaches in the tropics and sub-tropics. Green turtles use the earth’s magnetic field like an invisble map to navigate throughout their migrations. Like … Read more
