Turtle graphics are often associated with the Logo programming language. [2] Seymour Papert added support for turtle graphics to Logo in the late 1960s to support his version of the turtle robot, a simple robot controlled from the user's workstation that is designed to carry out the drawing functions assigned to it using a small retractable pen set into or attached to the robot's body.

The turtle shell is a shield for the ventral and dorsal parts of turtles (the order Testudines), completely enclosing all the vital organs of the turtle and in some cases even the head. [1] It is constructed of modified bony elements such as the ribs, parts of the pelvis and other bones found in most reptiles.
Turtle robots are commercially available and are common projects for robotics hobbyists. Turtle robots are closely associated with the work of Seymour Papert and the common use of the Logo programming language in computer education of the 1980s. Turtles specifically designed for use with Logo systems often come with pen mechanisms allowing the ...

Odontochelys semitestacea (meaning "toothed turtle with a half-shell") is a Late Triassic relative of turtles [1].Before Pappochelys was discovered and Eunotosaurus was redescribed, [2] Odontochelys was considered the oldest undisputed member of Pantestudines (i.e. a stem-turtle).
When this happens, the turtle's head extends out of its shell at a high velocity in order to grab and then eat the prey. [ 5 ] [ 6 ] In a 2009 video from Animal Planet 's show River Monsters , this turtle is seen quickly extending its head and long retractable neck out of its shell.
