| valign="top" | Requiem sharks are migratory, live-bearing sharks of warm seas (sometimes of brackish or fresh water) such as the [[Hiu harimau|tiger shark]], the [[blue shark]], the [[Hiu banteng|bull shark]], and the [[milk shark]]. The usual carcharhiniform characteristics include round eyes and [[pectoral finsfin]]s that are completely behind five gill slits. Most species are [[Vivipar|viviparous]], the young being born fully developed. They vary widely in size, from as small as {{Convertconvert|69|cm|ft|abbr=on}} adult length in the [[Australian sharpnose shark]], up to {{Convertconvert|5.5|m|ft|abbr=on}} adult length in the [[Hiu harimau|tiger shark]].<ref>Compagno, L.J.V.

| valign="top" | Weasel sharks are found from the eastern [[Samudra Atlantik|Atlantic Ocean]] to the continental [[Indo-Pasifik|Indo-Pacific]] in shallow coastal waters to a depth of 100&nbsp;m (330&nbsp;ft).<ref name="fishbase">Froese,{{FishBase Rainer, and Daniel Pauly, eds. (family|family=Hemigaleidae|year=2011). |month=February}}</ref> Most species are small, reaching no more than 1.4 m long (4.6&nbsp;ft), though the [[snaggletooth shark]] (''Hemipristis elongatus'') may reach 2.4&nbsp;m (7.9&nbsp;ft). They have horizontally oval [[Mata|eyes]], small spiracles[[spiracle]]s, and precaudal pits. Two [[Sirip punggung|dorsal finsfin]]s occur, with the base of the first placed well forward of the [[pelvic finsfin]]s. The [[caudal fin]] has a strong ventral lobe and undulations on the dorsal lobe margin. They feed on a variety of small [[Osteichthyes|bony fishesfish]]es and [[Avertebrata|invertebratesinvertebrate]]s; at least two species specialize on [[Sefalopoda|cephalopodscephalopod]]s. They are not known to have attacked people.<ref name="compagno">Compagno, Leonard J. V. (1984) ''Sharks of the World: An Annotated and Illustrated Catalogue of Shark Species Known to Date''.

| valign="top" | The only species of barbeled houndshark is ''Leptocharias smithii''. It is a [[demersal]] species found in the coastal waters of the eastern Atlantic Ocean from [[Mauritania]] to [[Angola]], at depths of {{Convertconvert|10|-|75|m|ft|abbr=on}}. It favours muddy [[Habitat|habitatshabitat]]s, particularly around [[Muara|river mouthsmouth]]s. The barbeled houndshark is characterized by a very slender body, nasal barbels, long furrows at the corners of the mouth, and [[Dimorfisme seksual|sexually dimorphic]] teeth. Its maximum known length is {{Convertconvert|82|cm|in|abbr=on}}. Likely strong-swimming and opportunistic, the barbeled houndshark has been known to ingest [[Osteichthyes|bony fishesfish]]es, [[Avertebrata|invertebratesinvertebrate]]s, [[Telur|fish eggsegg]]s, and even inedible objects. It is [[Vivipar|viviparous]], with females bearing litters of seven young; the developing [[Embrio|embryosembryo]]s are sustained by a unique globular [[Plasenta|placentalplacenta]]l structure. The [[UniInternational InternasionalUnion untukfor KonservasiConservation of AlamNature|IUCN]] has assessed the barbeled houndshark as [[Spesies mendekati terancam|near threatened]], as heavy fishing pressure occurs throughout its range and it is used for meat and [[Kulit (produk hewan)|leather]].

| valign="top" | False catsharks are a small [[Familiafamily (biology)|family]] containing false catsharks and gollumsharks. It contains the only ground shark species to exhibit intrauterine [[oophagy]], in which developing [[Janin|fetusesfetus]]es are nourished by eggs produced by their mother.<ref name="Fishbase">Froese,{{FishBase Rainer,family and| Danielfamily Pauly,= eds.Pseudotriakidae| (2012).month = December| year = 2012}}</ref>

| valign="top" | Catsharks are distinguished by their elongated, [[cat]]-like eyes and two small dorsal fins set far back. They usually have a patterned appearance, ranging from stripes to patches to spots. Most are fairly small, growing no longer than {{Convertconvert|80|cm|in|abbr=on}}; a few, such as the [[nursehound]], can reach {{Convertconvert|1.6|m|ft|abbr=on}} in length. They are found in [[temperate]] and [[tropical]] seas worldwide, ranging from shallow [[intertidal]] waters to depths of {{Convertconvert|2000|m|ft|abbr=on}} or more, depending on species.<ref>Froese,{{FishBase Rainer, and Daniel Pauly, eds. (family|family=Scyliorhinidae|year=2009). |month=January}}</ref> They feed on [[Avertebrata|invertebratesinvertebrate]]s and smaller [[fish]]. Some species are [[aplacental viviparous]], but most lay eggs in tough egg cases with curly tendrils at each end, known as [[mermaid's pursespurse]]s. The swell sharks of the genus ''[[Cephaloscyllium]]'' fill their stomachs with water or air when threatened, increasing their girth by a factor of two to three. Some catsharks are called [[Dogfish (disambiguation)|dogfish]].

| valign="top" | Hammerhead sharks are named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a "hammer" shape called a [[cephalofoil]]. Many, not necessarily mutually exclusive, functions have been proposed for the cephalofoil, including sensory reception, manoeuvring, and prey manipulation. Hammerheads are found worldwide in warmer waters along coastlines and [[continental shelves]]. Unlike most sharks, hammerheads usually swim in schools during the day, becoming solitary hunters at night.

| valign="top" | Houndsharks are distinguished by large spineless dorsal fins, an anal fin, and oval eyes with nictitating eyelids. They are small to medium in size, ranging from {{Convertconvert|37|to|220|cm|ft|abbr=on}} in adult length. They are found throughout the world in warm and temperate waters, where they feed on fish and invertebrates on the sea bed and in midwater.<ref>Froese, Rainer, and Daniel Pauly, eds.
