The hammerhead sharks are a group of sharks that form the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a cephalofoil. Most hammerhead species are placed in the genus Sphyrna, while the winghead shark is placed in its own genus, Eusphyra. Many, but not necessarily mutually exclusive, functions have been postulated for the cephalofoil, including sensory reception, manoeuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and continental shelves. Unlike most sharks, some hammerhead species usually swim in schools during the day, becoming solitary hunters at night. Some of these schools can be found near Malpelo Island in Colombia, the Galápagos Islands in Ecuador, Cocos Island off Costa Rica, near Molokai in Hawaii, and off southern and eastern Africa.
Penguins are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere, with only one species, the Galápagos penguin, found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch while swimming underwater. They spend roughly half of their lives on land and the other half in the sea.
A booby is a seabird in the genus Sula, part of the family Sulidae. Boobies are closely related to the gannets (Morus), which were formerly included in Sula.
Accipiter is a genus of birds of prey in the family Accipitridae. With 51 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although almost all New World species are simply known as hawks. They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.
Takifugu is a genus of pufferfish, often better known by the Japanese name fugu. There are 25 species belonging to the genus Takifugu and most of these are native to salt and brackish waters of the northwest Pacific, but a few species are found in freshwater of Asia or more widely in the Indo-Pacific region. Their diet consists mostly of algae, molluscs, invertebrates and sometimes crustaceans. The fish defend themselves by inflating their bodies to several times normal size and by poisoning their predators. These defenses allow the fish to actively explore their environment without much fear of being attacked.
The New Guinea big-eared bat, species Pharotis imogene, is a vespertilionid bat endemic to Papua New Guinea. It is listed as a critically endangered species due to ongoing habitat loss. It is the only known member of the genus Pharotis, which is closely related to Nyctophilus.
Macrochelys is a genus of very large freshwater turtles in the family Chelydridae from Southeastern United States. Only a single extant species was recognized until a 2014 study divided it into two, or possibly three species.
The rasptooth dogfish is a dogfish, found on the Kyushu-Palau Ridge in the northwest Pacific Ocean at depths of 360 m. Its maximum length is unknown. This species was originally described as Centroscyllium sheikoi, and subsequently allocated to the newly-named genus Miroscyllium based on anatomical features not shared with other Centroscyllium. More recent molecular data suggest this species belongs to the genus Etmopterus, but as of June 2014 Miroscyllium sheikoi remains the valid name recognized by FishBase, the Catalog of Fishes World Register of Marine Species, and the IUCN
Avenionia roberti is a species of minute freshwater snail with a gill and an operculum, an aquatic gastropod mollusk or micromollusk in the family Hydrobiidae.
The lesser yellow-shouldered bat is a species of bat in the family Phyllostomidae. It is native to Peru and Ecuador. It is threatened by habitat loss.
Speleoperipatus is a monospecific genus of velvet worm in the Peripatidae family, containing the single species Speleoperipatus spelaeus.
Helicia is a genus of 110 species of trees and shrubs, constituting part of the plant family Proteaceae. They grow naturally in rainforests throughout tropical South and Southeast Asia, including India, Sri Lanka, Indochina, Peninsular Malaysia to New Guinea and as far south as New South Wales.
The montane monkey-faced bat is a megabat endemic to the Solomon Islands. It is listed as a critically endangered species. Due to its imperiled status, it is identified by the Alliance for Zero Extinction as a species in danger of imminent extinction. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation. Only one individual has ever been found.
The Makira flying fox is a species of megabat in the genus Pteropus, found in the Solomon Islands. The species is currently decreasing and is endangered due to threats from logging and hunting. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation.
Cyclostoma is an obsolete genus name of operculate snails with circular aperture.
The olinguito is a mammal of the raccoon family Procyonidae that lives in montane forests in the Andes of western Colombia and Ecuador. It was classified as belonging to a new species in 2013. The specific name neblina is Spanish for fog or mist, referring to the cloud forest habitat of the olinguito.
The Yamdena mosaic-tailed rat is a species of rat belonging to the family Muridae. It was first described in 1995 from specimens found on Yamdena Island in Indonesia. No other examples of this species have been found; as a result very little is known about it. IUCN lists it as Data Deficient.
