Turtle(Aquatic or Land)

Turtles are reptiles of the order Chelonii^[2] or Testudines characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield.^[3] Turtle may refer to the chelonian order as a whole (American English) or to fresh-water and sea-dwelling chelonians (British English).^[4]

The order Chelonii or Testudines includes both extant (living) and extinct species. The earliest known turtles date from220 million years ago,^[5] making turtles one of the oldest reptile groups and a more ancient group than lizards, snakes or crocodiles. Of the many species alive today, some are highly endangered.^[6]

Turtles are ectotherms—their internal temperature varies according to the ambient environment, commonly called cold-blooded. However, because of their high metabolic rate, leatherback sea turtles have a body temperature that is noticeably higher than that of the surrounding water.

Turtles are classified as amniotes, along with other reptiles (including birds) and mammals. Like other amniotes, turtles breathe air and do not lay eggs underwater, although many species live in or around water.

Koi Fish (Aquatic Fish)

Koi (鯉^?, English /ˈkɔɪ/, Japanese: [koꜜi]) or more specifically nishikigoi (錦鯉^?, [niɕi̥kiꜜɡo.i], literally "brocaded carp"), are a group of fish that are ornamental varieties of domesticated common carp (Cyprinus carpio) that are kept for decorative purposes in outdoor koi ponds or water gardens.

Koi varieties are distinguished by coloration, patterning, and scalation. Some of the major colors are white, black, red, yellow, blue, and cream. The most popular category of koi is the Gosanke, which is made up of the Kohaku, Taisho Sanshoku, and Showa Sanshoku varieties.

ChihuAchuA'S history (lanD animalS)

The Chihuahua’s history is puzzling and there are many theories surrounding the origin of the breed. Both folklore and archaeological finds show that the breed originated in Mexico. The most common and most likely theory is that Chihuahuas are descended from the Techichi, a companion dog favored by the Toltec civilization in Mexico.^[2] No records of the Techichi are available prior to the 9th century, although dog pots from Colima, Mexico, buried as part of the western Mexico shaft tomb tradition which date back to 300 BC are thought to depict Techichis.^[3] It is probable that earlier ancestors were present prior to the Mayans as dogs approximating the Chihuahua are found in materials from the Great Pyramid of Cholula, predating 1530 and in the ruins of Chichen Itza on the Yucatán Peninsula.^[2]
In fact, wheeled dog toys representing both the "deer head" and "apple head" varieties of Chihuahua have been unearthed across Mesoamerica from Mexico to El Salvador. The earliest of these were found at Tres Zapotes in Veracruz, Mexico, which date to 100 AD.^[4] Dog effigy pots dating to around 1325 AD discovered in Georgia and Tennessee also appear to represent the Chihuahua^[5] It has been argued that these pots arrived with survivors from the Casas Grandes site in Chihuahua, Mexico, after it was attacked and destroyed around 1340 AD. Pots unearthed at Casas Grandes include representations of the "deer head" variety of Chihuahua.^[4] Hernan Cortés wrote, in a 1520 letter, that the Aztecs raised and sold the little dogs as food.^[6] Colonial records refer to small, nearly hairless dogs at the beginning of the 19th century, one of which claims 16th-century Conquistadores found them plentiful in the region later known as Chihuahua.^[7]
A progenitor of the breed was reputedly found in 1850 in old ruins near Casas Grandes in the Mexican state of Chihuahua from which the breed gets its name,^[8] although most artifacts relating to its existence are found around Mexico City. A pot featuring the "deer head" variety of Chihuahua has been unearthed at Casas Grandes which dates from 1100–1300 AD showing the long history of the breed at this site.^[4] A wheeled dog toy which has been dated to 100 AD from Tres Zapotes in Veracruz, Mexico, depicts a dog identical in appearance and size to the modern Chihuahua, indirect evidence that the breed was in Mexico over 1400 years before the first Europeans arrived.^[4] The Chihuahua has remained consistently popular as a breed, particularly in America when the breed was first recognized by the American Kennel Club in 1904.^[2]

Description

Chihuahuas are very small dogs, and are the smallest breed recognized by some kennel clubs.^[9] There are two main varieties recognized by kennel clubs, the short-haired and the long-haired.^[9] There is a second varietal split as well, having to do with the shape and size of the dog's head. These two descriptive classifications are "apple head" and "deer head", but only the apple head is conformationally correct.^[10]

Appearance

Breed standards for this dog do not generally specify a height; only a weight and a description of their overall proportions. Generally, the height ranges between 15 and 23 cm (6 and 9 in);^[9] however, some dogs grow as tall as 30 to 38 cm (12 to 15 in).^[11] Both British and American breed standards state that a Chihuahua must not weigh more than 2.7 kg (6 lb) for conformation.^[9] However, the British standard also states that a weight of 1.8–2.7 kg (4–6 lb) is preferred ^[12] and that if two dogs are equally good in type, the more diminutive one is preferred. The Fédération Cynologique Internationale (FCI) standard calls for dogs ideally between 1.5 and 3.0 kg (3.3 and 6.6 lbs.), although smaller ones are acceptable in the show ring.^[13] Pet-quality Chihuahuas (that is, those bred or purchased as companions rather than show dogs) often range above these

hammEr heaD sharK(aquaTic fiSh)

The hammerhead sharks are a group of sharks in 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 not necessarily mutually exclusive functions have been proposed for the cephalofoil, including sensory reception, maneuvering, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and continental shelves. Unlike most sharks, hammerheads usually swim in schools during the day, becoming solitary hunters at night. Some of these schools can be found near Malpelo Island in Colombia, Cocos Island off Costa Rica, and near Molokai Island in Hawaii. Large schools are also seen in southern and eastern Africa.

whalE(aquatIc fiSh)

 Whale (origin Old English hwæl from Proto-Germanic *hwalaz) is the common name for various marine mammals of the order Cetacea.^[1]The term whale sometimes refers to all cetaceans, but more often it excludes dolphins and porpoises, which belong to the suborderOdontoceti (toothed whales). This suborder includes the sperm whale, killer whale, pilot whale, and beluga whale. The other Cetacean suborder, Mysticeti (baleen whales), comprises filter feeders that eat small organisms caught by straining seawater through a comblike structure found in the mouth called baleen. This suborder includes the blue whale, the humpback whale, the bowhead whale and the minke whale. All cetaceans have forelimbs modified as fins, a tail with horizontal flukes, and nasal openings (blowholes) on top of the head.

Whales range in size from the blue whale, the largest animal known to have ever existed^[2] at 30 m (98 ft) and 180 tonnes (180 long tons; 200 short tons), to pygmy species such as the pygmy sperm whale at 3.5 m (11 ft). Whales inhabit all the world's oceans and number in the millions, with annual population growth rate estimates for various species ranging from 3% to 13%.^[3] Whales are long-lived, humpback whales living for up to 77 years, while bowhead whales may live for over a century.

Human hunting of whales from the 17th century until 1986 radically reduced the populations of some whale species. Whales have appeared in literature since the time of the Old Testament, play a role in Inuit creation myths, and are revered by coastal people in Ghana and Vietnam.

raT sNakE(laNd anImalS)

Rat snakes are medium to large constrictors found through a great portion of the Northern Hemisphere. They feed primarily on rodents and birds. With some species exceeding 3 m (10 ft) in total length, they can occupy top levels of some food chains. Many species make attractive and docile pets and one, the corn snake, is one of the most popular reptile pets in the world.^{[citation needed]} Other species can be very skittish and sometimes aggressive, but bites are rarely serious. Like nearly all colubrids, rat snakes pose no threat to humans. Rat snakes were long thought to be completely nonvenomous, but recent studies have shown that some Old World species do possess small amounts of venom (so small as to be negligible to humans).^{[citation needed]}
Previously, most rat snakes were assigned to the genus Elaphe, but many have been since renamed following mitochondrial DNA analysis performed in 2002. For the purpose of this article, names will be harmonized with the TIGR Database
