lungfish





Lungfish aren't that bizarre. Everyone knows they have the ability to breathe air. What is really bizarre is their estivation. Estivation is is a rare state of dormancy similar to hibernation, but during the months of the summer. Animals that estivate spend a summer inactive and insulated against heat to avoid the potentially harmful effects of the season (such as the increase in temperature or relative lack of water), or to avoid contact with other species with which they may otherwise be in competition, or for which they are prey.The lungfish estivates by burying itself in mud formed at the surface of a dried up lake. In this state, the lungfish can survive for many years.Lungfish can be extremely long-lived. The Queensland species lungfish at the Shedd Aquarium in Chicago has been part of the permanent live collection since 1933.

Glass frogs



the general background coloration of most glassfrogs is primarily lime green; the ventral skin of some members of this family is transparent. The internal viscera, including the heart, liver and digestive tract can be seen due to the translucency of the ventral skin.

Mimic Octopus


Not officially discovered until 1998, the Mimic octopus can change its texture, arm positioning, and movement, the mimic octopus is able to imitate around seventeen other animals, including lionfish, sea snakes, flatfish, and brittle stars.
Although all species of octopus have the ability to change the color and texture of their skin, and many species can blend in with the sea floor and look like rocks, the mimic octopus is the first octopus species ever observed to impersonate other animals.

Coconut crab








The coconut crab is the largest land-living arthropod in the world. It is a derived hermit crab and is known for its ability to crack coconuts with its strong pincers in order to eat the contents. It is also called the robber crab or palm thief, because some coconut crabs are rumored to steal shiny items such as pots and silverware from houses and tents.

this is NOT a snake!



The 7-inch (18-centimeter) creature is not a serpent at all, but actually a completely new species of limbless lizard. The lizard is new to science and is an important discovery. It is not found anywhere else in the world but India.

Almiqui




A farmer in Holguin province recently discovered an almiqui, a worm-eating, nocturnal creature recently believed to be extinct. The almiqui was last sighted in 1999 and before that in 1977. It's presence in eastern Cuba was first noted by naturalists in the 19th century and since then has been seen only a handful of times. The almiqui was a victim of development - - the deforestation of Cuba - - and the importation of alien species to the largest island in the Caribeann, especially dogs.
