Land snails move by gliding along on their muscular foot, which is lubricated with mucus and covered with epithelial cilia. [9] This motion is powered by succeeding waves of muscular contractions that move down the ventral of the foot. This muscular action is clearly visible when a snail is crawling on the glass of a window or aquarium. [10]
The rotation is fast, the golden wheel spider (Carparachne aureoflava) moving up to 20 revolutions per second, moving the spider at 1 metre per second (3.3 ft/s). [ 14 ] Coastal tiger beetle larvae when threatened can flick themselves into the air and curl their bodies to form a wheels, which the wind blows, often uphill, as far as 25 m (80 ft ...
The highest reliably measured running speed for ostriches is 61 km/h (38 mph), obtained by speedometer reading when a car was chasing an ostrich in a straight line chase to force it to move as fast as it could. [53] Although there are reports of speeds of 72–97 km/h (45–60 mph) for ostriches, none are confirmed. [54] Emu (on land)
The snail takes 30–40 days to hatch and is then considered young (before sexual maturity). Sexual maturity begins between 4 and 16 months after hatching. The snail is relatively fast moving at about 8 mm/s. [3] The snail has a light grey or brown body, with its lower tentacles being long and almost touching the ground.
The anatomy of a common air-breathing land snail: much of this anatomy does not apply to gastropods in other clades or groups. Snails are distinguished by an anatomical process known as torsion, where the visceral mass of the animal rotates 180° to one side during development, such that the anus is situated more or less above the head. This ...

The snail secretes thixotropic adhesive mucus that permits locomotion by rhythmic waves of contraction passing forward within its muscular foot. Starting from the rear, the contraction of the longitudinal muscle fibres above a small area of the film of mucus causes shear that liquefies the mucus, permitting the tip of the tail to move forward.
