Ковровые акулы - это акулы , классифицированные в порядке Orectolobiformes / ɒ r ɛ K ˈ T ɒ L ə b ɪ f ɔːr m iː z / . Иногда общее название «ковер -акула» (так называемое так, потому что многие виды напоминают богато узорчатые ковры ) используется взаимозаменяемо с «Wobbegong», что является общим названием акул в семействе Orectolobidae . У ковровых акул есть пять жабр , два бесконечных дорсальных плавника и маленький рот, который не простирается мимо глаз. Многие виды имеют варки .
Характеристики
[ редактировать ]Ковровые акулы представляют собой разнообразную группу акул с разными размерами, внешностью, диетами и привычками. Сначала они появились в ископаемом отчете в ранней юре ; Самыми старейшими известными родами по общему количеству являются Folipistrix (известный от Toarcian до аалениана в Бельгии и Германии ), Palaeobrachaelurus (от Aalenian -Barremian ) и Annea (Toarcian to Bajocian в Европе). [ 1 ] Все виды имеют два дорсальных плавника и относительно короткий, поперечный рот, который не простирается за глазами. Кроме того, ноздри - варки , тактильные сенсорные органы и канавки, известные как носоральные канавки, соединяют ноздри ко рту. Пять коротких прорезей жабры находятся прямо перед началом грудного плавника, а пятая щель имеет тенденцию перекрывать четвертый. [2] A spiracle occurs beneath each eye which is used in respiration. The only exception to this rule is the whale shark, the spiracles of which are situated just behind the eyes.[3] Carpet sharks derive their common name from the fact that many species have a mottled appearance with intricate patterns reminiscent of carpet designs. The patterning provides camouflage when the fish is lying on the seabed.[4] The largest carpet shark is the whale shark (Rhincodon typus) which can grow to a length of 14 m (46 ft). It is the largest species of fish, but despite its size, is not dangerous, as it is a filter feeder, drawing in water through its wide mouth and sifting out the plankton. The smallest carpet shark, at up to about 30 cm (12 in) long, is the barbelthroat carpet shark, (Cirrhoscyllium expolitum).[3] Некоторые из наиболее впечатляющих цветных членов Ордена - это колье -ковровая акула ( Parascyllium variolatum ), акула зебры ( фарсатор стегостомы ) и украшенное воббегонг ( orectolobus ornatus ). У медсестер -акул и китов есть бахрома баржельков на своих мордах, а ковровые акулы из шариль -платы ( Cirrhoscyllium expolitum ) заставляют шарли, свисающие из их горло.
Behaviour
[edit]Most carpet sharks feed on the seabed in shallow to medium-depth waters, detecting and picking up molluscs, crustaceans, and other small creatures.[3] The wobbegongs tend to be ambush predators, lying hidden on the seabed until prey approaches. One has been observed swallowing a bamboo shark whole.[5]
The methods of reproduction of carpet sharks varies. Some species are oviparous and lay eggs which may be liberated directly into the water or may be enclosed in horny egg cases. Some female sharks have been observed to push egg cases into crevices and this would be an added protection for the developing embryos. Other species are ovoviviparous and the fertilised eggs are retained in the mother's oviduct. There, the developing embryos, which are usually few in number, feed on their yolk sacs at first and later hatch out and feed on nutrients secreted by the walls of the oviduct. The young are born in an advanced state, ready to live independent lives.[3]
Distribution
[edit]Carpet sharks are found in all the oceans of the world but predominantly in tropical and temperate waters. They are most common in the western Indo-Pacific region and are usually found in relatively deep water.[3]
Classification
[edit]The order is small, with seven families in 13 genera and with a total of around 43 species:
| Family | Image | Common name | Genera | Species | Description |
|---|---|---|---|---|---|
| Brachaeluridae | 
|
Blind sharks | 1 | 2 | Blind sharks are found in shallow coastal waters up to 110 m (360 ft) deep off the eastern coast of Australia.[6] They are distinguished by the presence of long barbels, large spiracles, and grooves around the nostrils. They have two dorsal fins, placed close together on the back, and a relatively short tail. Blind sharks feed on small fish, cuttlefish, sea anemones, and crustaceans. The female retains the eggs in her body until they hatch (ovoviviparity), during which time the embryos feed solely on the egg yolk.[6] Despite their name, blind sharks are not blind; their name comes from their habit of closing their eyes when taken out of water.[6] There are only two species. |
| Ginglymostomatidae | 
|
Nurse sharks | 3 | 4 | Nurse sharks have long tails and distinctive mouths which are far ahead of the eyes and before the snout (subterminal), an indication of the bottom-dwelling (benthic) nature of these sharks. Also present on the lower jaw are two fleshy barbels, chemosensory organs which help the nurse sharks find prey hidden in the sediments. Common in shallow, tropical, and subtropical waters, these sharks are sluggish and docile bottom-dwellers. Nurse sharks typically attack humans only if directly threatened. The largest species can reach a length of 4.3 m (14 ft).[7] |
| Hemiscylliidae | 
|
Bamboo sharks | 2 extant 4 extinct | 16 extant 6 extinct | Bamboo sharks, sometimes called longtail carpet sharks, are distinguished by a relatively long snout with subterminal nostrils.[8] They are relatively small sharks, with the largest species reaching only 121 cm (48 in) in length. They have elongated, cylindrical bodies, with short barbels and large spiracles. As their common name suggests, they have unusually long tails, exceeding the length of the rest of their bodies. They are found in shallow waters of the tropical Indo-Pacific. They are sluggish fish, feeding on bottom-dwelling invertebrates and smaller fish.[9] |
| Orectolobidae | 
|
Wobbegong sharks | 3 extant 1 extinct | 12 extant 1 extinct | Wobbegong sharks are well camouflaged with symmetric, bold patterns resembling a carpet. The camouflage is improved by the presence of small weed-like whisker lobes surrounding the jaw, which help to camouflage it and act as sensory barbs.[10] Wobbegongs are bottom-dwelling and spend much time resting on the sea floor. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia. Most species have a maximum length of 1.25 m (4.1 ft) or less, and the largest reach about 3 m (9.8 ft) in length. Wobbegongs are generally not dangerous to humans unless provoked.[11] |
| Parascylliidae | 
|
Collared carpet sharks | 2 | 8 | Collared carpet sharks have elongated, slender bodies, cat-like eyes, and barbels behind their chins. They are found only in the shallow waters of the western Pacific. They are relatively small sharks, with the largest species reaching no more than 91 cm (2.99 ft) in adult length.[12] |
| Rhincodontidae | 
|
Whale sharks | 1 | 1 | The whale shark is the largest extant fish species, growing over 12 m (40 ft) long and weighing over 20 tonnes (45,000 lb). It is a slow-moving filter feeder with a very large mouth, feeding mainly, though not exclusively, on plankton. The whale shark is a pelagic species, living in the open sea in tropical and warm oceans with a lifespan around 70 years.[13] The IUCN has assessed it as Endangered.[14] |
| Stegostomatidae | 
|
Zebra sharks | 1 | 1 | Zebra sharks are distinctive in appearance, with five longitudinal ridges on a cylindrical body, a low caudal fin comprising nearly half the total length, and a pattern of dark spots on a pale background. They grow to a length of 2.5 m (8.2 ft), and are found throughout the tropical Indo-Pacific, frequenting coral reefs and sandy flats to a depth of 62 m (210 ft). They are nocturnal and spend most of the day resting motionless on the sea floor. They are innocuous to humans. The IUCN has assessed them as endangered and their populations are likely in decline.[15] |
