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.
