Instead of flopping or crutching, the cave fish were using what looked like a full-blown tetrapod gait.

Crutching has to be repeated at regular intervals as the wool grows continuously. Frequent crutching of Merinos reduces the incidence of flystrike, but not as much as mulesing. At the time mulesing was invented, crutching was done with blade shears. In Australia, these have been almost universally replaced with machine shears.

Docking (removing) sheep's tails has much the same benefits for the sheep as crutching. While this procedure may reduce the care needed to keep wool clean, regular crutching may still required for the reasons outlined above. Crutching is different to mulesing where part of the wrinkled skin is removed, although they are closely related in that mulesed sheep require much less crutching. It is the excess wool which gets most soiled from urination and faeces, and which can be perceived to be particularly dirty due to green feeding, rapid changes in feed, or from problems such as internal parasites.

Crutching a sheep that has been wigged (eye-wooled). Freshly crutched and wigged Merino sheep. Crutching refers to the removal of wool from around the tail and between the rear legs of a sheep for hygiene purposes. It can also refer to removing wool from the heads of sheep (wigging or eye-wooling).

Hand shears were being used when Mules inadvertently carried out the procedure during crutching. Mulesing would not inadvertently occur using modern machine shears.

Mulesing is different from crutching. Crutching is the mechanical removal of wool around the tail, anus (and vulva in ewes) in breeds of sheep with woolly points where this is necessary. Mulesing is the removal of skin to provide permanent resistance to breech strike in Merino sheep. Other breeds tend to have less loose skin and wool so close to the tail, and may have less dense wool.

Shearing a Merino in Lismore, Victoria, Australia. Shearing shed, meat house and shearers' quarters on a station, Northern Tablelands, New South Wales, Australia. A sheep shearer is a worker who uses (hand-powered)-blade or machine shears to remove wool from domestic sheep during crutching or shearing.

Urine and watery faeces from eating spring grass can also lead to myiasis (fly-strike), which occurs when flies lay eggs in warm, damp wool and the fly larvae grow and eat into the sheep. Crutching is an effective way to help prevent this; in some areas, crutching is carried out at the start of the fly season (which depends on local climatic conditions) and may be needed at intervals of 6–8 weeks in high fly risk conditions. Rams and wethers may also be rung (crutched) on the belly around the pizzle (cock) to prevent fly- strike there. Wigging (removal of wool from the head of sheep) is carried out to prevent the sheep from becoming "wool blind", in which the wool covers the sheep's eyes.

Routine procedures include supervising crutching, mating, shearing, treating for ticks, lice and maggots (if necessary), lambing and lamb marking. Lambs are weaned at about five months of age. Drenching for internal parasites is an important routine on a sheep station. Other activities include ram buying and classing the sheep in order to determine the inferior types that are to be culled.

Due to this process, the energy of the sheep is directed into meat and milk, not wool. The breed is, therefore, very low maintenance as it has no need for shearing, crutching, mulesing, jetting, dipping, and docking of tails. The Wiltipoll is grass seed-resistant and fly- and lice-resistant, reducing the need for chemicals or the painful practice of mulesing. All this equates to less expense and less work.

The Dorper has a thick skin, which is highly prized and protects the sheep under harsh climatic conditions. The Dorper skin is the most sought-after sheepskin in the world and is marketed under the name of Cape Glovers. The skin comprises a high percentage of the income (20%) in South Africa. Unlike Merinos, Dorpers do not need shearing, crutching, or mulesing, and they are much less prone to flystrike.

The limbs could not move alternately as they lacked the necessary rotary motion range. In addition, the hind limbs lacked the necessary pelvic musculature for hindlimb-driven land movement. Their most likely method of terrestrial locomotion is that of synchronous "crutching motions", similar to modern mudskippers. (Viewing several videos of mudskipper "walking" shows that they move by pulling themselves forward with both pectoral fins at the same time (left & right pectoral fins move simultaneously, not alternatively).

In addition to other treatments, crutching (shearing wool from a sheep's rump) is a common preventive method. Some countries allow mulesing, a practice that involves stripping away the skin on the rump to prevent fly-strike, normally performed when the sheep is a lamb. Nose bots are fly larvae that inhabit a sheep's sinuses, causing breathing difficulties and discomfort. Common signs are a discharge from the nasal passage, sneezing, and frantic movement such as head shaking.

Wiltipolls are large, easy- care, plain-bodied sheep that shed their wool annually. They do not require crutching or shearing and do not suffer readily from fly strike, which makes them a useful breed for small holdings without shearing sheds. These sheep must have at least 96.87% Wiltshire Horn genetics, completely shed their fleece annually, and be polled. The ewes are seasonal breeders, but are good mothers, have high fertility with a high percentage of multiple births.

The Van Rooy, also known as the Van Rooy White Persian, is a breed of domestic sheep native to South Africa. The Van Rooy was first developed in 1906 by (and named for) J. C. van Rooy, a South African Senator and farmer in the Bethulie district. The Van Rooy is cross between indigenous Ronderib Afrikaner sheep, and Rambouillets. It is a fat-tailed sheep and also a hair sheep, removing the need for shearing and crutching.

He dropped out of classes because he says "didn't want to be crutching around campus" and he eventually stopped rehabbing his knee and became irregular with his workouts. After the injury, he dropped out of school and fell onto hard times. Boles compiled 10 100-yard games while rushing for in two years at Michigan. In addition to playing running back, Boles excelled as a kick returner where he accumulated and a touchdown on 25 returns for a per return average.

His machines made in Birmingham, England, by his business The Wolseley Sheep Shearing Machine Company were introduced after 1888, reducing second cuts and shearing time. By 1915 most large sheep station sheds in Australia had installed machines, driven by steam or later by internal combustion engines. Shearing tables were invented in the 1950s and have not proved popular, although some are still used for crutching. In the US, the worldwide shortage of shearers is becoming a consideration for those wanting to expand wool production.

A species of mudskipper (Periophthalmus gracilis) Fin and flipper locomotion occurs mostly in aquatic locomotion, and rarely in terrestrial locomotion. From the three common states of matter — gas, liquid and solid, these appendages are adapted for liquids, mostly fresh or saltwater and used in locomotion, steering and balancing of the body. Locomotion is important in order to escape predators, acquire food, find mates and bury for shelter, nest or food. Aquatic locomotion consists of swimming, whereas terrestrial locomotion encompasses walking, 'crutching', jumping, digging as well as covering.

The BL755 looks like a standard general-purpose bomb but with a hard "saddle" on the spine for ejector release and crutching pad loads and a distinctive large turbine-like air arming vane on the nose. The four rear fins are squared off in appearance, but on closer inspection can be seen to be hollow and telescopic. A central extruded aluminum skeleton is divided into seven bays, each containing 21 submunitions (147 total). The bays are covered by a frangible cover that the submunitions break during ejection.

Mudskippers in The Gambia Terrestrial locomotion poses new obstacles such as gravity and new media, including sand, mudd, twigs, logs, debris, grass and many more. Fins and flippers are aquatically adapted appendages and typically aren't very useful in such an environment. It could be hypothesized that fish would try to "swim" on land, but studies have shown that some fish evolved to cope with the terrestrial environment. Mudskippers, for example demonstrate a 'crutching' gait which enables them to 'walk' over muddy surfaces as well as dig burrows to hide in.

Crutching a sheep that has been wigged (eye-wooled). A professional or "gun" shearer typically removes a fleece, without badly marking or cutting the sheep, in two to three minutes depending on the size and condition of the sheep, or less than two in elite competitive shearing. Shearers who “tally” more than 400 sheep per day when shearing crossbreds, or around 200 for finer wool sheep such as merino, are known as “gun shearers”. Gun shearers using blade shears are usually shearers that have shorn at least 200 sheep in a day.

One alternative prevention method is the sterile insect technique (SIT) where a significant number of artificially reared sterilized (usually through irradiation) male flies are introduced. The male flies compete with wild breed males for females in order to copulate and thus cause females to lay batches of unfertilized eggs which cannot develop into the larval stage. One prevention method involves removing the environment most favourable to the flies, such as by removal of the tail. Another example is the crutching of sheep, which involves the removal of wool from around the tail and between the rear legs, which is a favourable environment for the larvae.

A Wiltshire Horn ewe and her triplets The Wiltshire Horn is a breed of domestic sheep originally from Wiltshire in southern England raised for meat. The breed is unusual among native British breeds, for it has the unusual feature of moulting its short wool and hair coat naturally in spring, alleviating the need for shearing. They are good mothers and have high fertility. The fact that they do not require shearing or crutching and do not suffer readily from flystrike is making them increasingly attractive to the commercial sheep sector, particularly as even pure-bred lambs can reach slaughter weight in as little as 16 weeks.
