fish taxon to exhibit more diversity of species at higher latitudes. A cool, temperate to polar water in the deep sea can be a favorable environment for skates. As the water becomes more shallow and warmer, skates are seen to be replaced by stingrays. Skates are absent from brackish and freshwater environments. However, there is a single estuarine species that has been found in Tasmania, Australia. Also, the Connecticut Department of Environmental Protection has caught and studied skates within the Long Island Sound estuary. Some skate fauna have been found inhabiting areas of rock cobble and high rocky relief.

lateral musculature of the notochord. The impulses put out by the electric organs of the skate are considered to be weak, asynchronous, long-lasting signals. Although the anatomy of the skate's electric organ is well described, its function is poorly understood. Some research suggests the electric impulses are too weak to be a mechanism used for defense or hunting. It is also too irregular to be useful for electrolocation purposes. The most reasonable explanation in the literature suggests that the electric organ discharges may be used as a form of communication used for reproduction purposes.

The size of the fibrous shell around the case is another characteristic. Some species have thick layers on the exterior.

The flattened body shape, ventral eyes and well developed spiracles of the skate allows them to live benthically, buried in the sediment

Skates are like stingrays in that they have five pairs of gill slits that are located ventrally, which means on the underside of their body (unlike sharks that have their gills located on their sides). Skates and rays both have pectoral fins that are flat and expanded, which are typically fused to

to glide along the water floor. Current research suggests that some species of skates, in addition to their Rajiform locomotion, use their pelvic fins to perform ambulatory locomotion. This form of locomotion performed by the skate is being explored as a possible origin for our own development of

Skates are primarily found from the intertidal down to depths greater than 3,000 m (9,843 ft). They are most commonly found along outer continental shelves and upper slopes. They are typically more diverse at higher latitudes and in deep-water. In fact, skates are the only cartilaginous

Skates produce their young in an egg case called a mermaid's purse. These egg cases have distinct characteristics that are individualized to each species. This makes a great tool for identifying different species of skates. One of these identifiable structures is the keel. The keel is a flexible

Skates are different from rays in that they lack a whip-like tail and stinging spines. However, some skates have electric organs located in their tail. The main difference between skates and rays is that skates lay eggs, whereas rays give birth to live young.
