Carpet shark

life science Maturity 5-7 Next article →

Carpet sharks belong to the biological order Orectolobiformes. This group is highly diverse, containing about 43 different species. They are characterized by specific physical traits that distinguish them from other sharks. All carpet sharks possess two dorsal fins on their backs. They also feature five short gill slits located just in front of their pectoral fins. Most species have a small, transverse mouth that does not extend past their eyes. Many also possess barbels, which are tactile sensory organs used to feel their surroundings.

Many species in this order use specialized anatomy to navigate and breathe. Besides their nostrils, they have grooves called nasoral grooves that connect the nostrils to the mouth. Most carpet sharks also use spiracles for respiration. A spiracle is a small opening used to take in water for breathing. In most species, these are located beneath the eyes. The whale shark is the unique exception to this rule. Its spiracles are positioned just behind its eyes instead.

The group is famous for its incredible variety in size and appearance. The whale shark, or Rhincodon typus, is the largest species of fish in the world. It can grow to a length of over 12 meters and weigh more than 20 tonnes. Despite its massive size, it is a filter feeder. It draws in water through a wide mouth to sift out tiny plankton. At the opposite end of the scale is the barbelthroat carpet shark. This tiny species grows to only about 14 centimeters in length.

Carpet sharks are categorized into seven distinct families. The Brachaeluridae family includes blind sharks, which are found near Australia. The Ginglymostomatidae family contains nurse sharks, which are docile bottom-dwellers. Bamboo sharks belong to the Hemiscylliidae family and are known for their long tails. The Orectolobidae family includes wobbegong sharks, which use bold patterns for camouflage.

The Parascylliidae family consists of slender collared carpet sharks. Finally, the Rhincodontidae family contains only the massive whale shark.

The history of Orectolobiformes stretches back to the Early Jurassic period. Scientists have identified several ancient genera in the fossil record. These include Folipistrix, which lived in what is now Belgium and Germany. Other ancient genera include Palaeobrachaelurus and Annea. These fossils provide a timeline for how these sharks have evolved over millions of years.

Reproduction methods vary significantly across the different species. Some carpet sharks are oviparous, meaning they lay eggs. Some females will even push their egg cases into rocky crevices for protection. Other species are ovoviviparous, meaning they retain fertilized eggs inside the mother's oviduct. In these cases, the embryos initially feed on their own yolk sacs. Later, they consume nutrients secreted by the walls of the oviduct. When these young are born, they are in an advanced state and ready to live independently.

Most carpet sharks live in tropical and temperate waters. They are most commonly found in the western Indo-Pacific region. Many species are benthic, meaning they live and feed on the seabed. They use their patterns to blend in with the ocean floor. This camouflage helps wobbegongs act as ambush predators. They lie hidden until prey, such as molluscs or crustaceans, approaches. This specialized way of life connects their physical appearance directly to their survival in the ecosystem.
