Nurse sharks food-13 Facts About Nurse Sharks | Mental Floss

Jump to navigation. Tropical to warm temperate latitudes in the eastern Pacific and eastern and western Atlantic oceans. The nurse shark is one of the most commonly observed sharks on coral and rocky reefs of the eastern Pacific Ocean and the eastern and western Atlantic Ocean. Given that nurse sharks give live birth and that individuals even juveniles have relatively small home ranges, it is surprising that all individuals across this large, tropical to warm temperate distribution are the same species. An extensive genetic study of the nurse shark may reveal the existence of different species in different ocean basins e.

Putting up with algae and coral in their diet is another mark of how little effort the nurse shark puts into eating. The nurse sharks are primarily feed on mollusks, sea snakes, fish, stingrays, algae, coral, crustaceans, and tunicates. Nurse sharks are slow-moving bottom-dwellers and are, for the most part, harmless to humans. Their diet consists primarily of crustaceans, mollusks, tunicates, sea snakes, and other fish, particularly stingrays.

The nurse shark Ginglymostoma cirratum is an elasmobranch fish within the family Ginglymostomatidae. They are directly targeted in some fisheries and considered as bycatch in others. The conservation status of the nurse shark is globally assessed as being data deficient in- the IUCN List of Threatened Species owing to the lack of information across its range in the eastern Pacific Ocean and eastern Atlantic Ocean.

Nurse sharks are an important species for shark research predominantly in physiology. The origin of the name "nurse shark" is unclear. It may come from the sucking sound they make when hunting for prey in the sand, which vaguely resembles that of a nursing baby. Or it may derive from an archaic word, nusse, meaning cat shark.

The most likely theory though is that the name comes from the Old English word for sea-floor shark: hurse. The nurse shark genus Ginglymostoma is derived from Greek language meaning hinged mouth, whereas the species cirratum is derived from Latin meaning having curled ringlets. Based on morphological similarities, Ginglymostoma is believed to be the sister genus of Nebrius , with both being placed in a clade that also include species Pseudoginglymostoma brevicaudatum , Rhincodon typus , and Stegostoma fasciatum.

The nurse shark has two rounded dorsal fins, rounded pectoral fins, an elongated caudal fin, and a broad head. Maximum adult length is currently documented as 3. The nurse shark has a wide but patchy geographical distribution along tropical and subtropical coastal waters of the Eastern Atlantic, Western Atlantic, and Eastern Pacific.

Nurse sharks are a typically inshore bottom-dwelling species. Juveniles are mostly found on the bottom of shallow coral reefs, seagrass flats, and around mangrove islands, whereas older individuals typically reside in and around deeper reefs and rocky areas, where they tend to seek shelter in crevices and under ledges during the day and leave their shelter at night to feed on the seabed in shallower areas.

Nurse sharks are opportunistic predators that feed primarily on small fish e. Nurse sharks are obligate suction feeders capable of generating suction forces that are among the highest recorded for any aquatic vertebrate to date. Nurse sharks are exceptionally sedentary unlike most other shark species. Nurse sharks are occasionally prey for American alligators Alligator mississippiensis where they share the same habitat.

Recent studies based on photographs and historical accounts indicate that these encounters may be more common than previously thought. Nurse sharks are ovoviviparous , producing young by means of eggs that are hatched within the body of the pregnant female. The mating cycle is biennial, taking 18 months for the female's ovaries to produce another batch of eggs. The mating season runs from late June to the end of July, with a gestation period of six months and a typical litter of 21—29 pups.

The Nurse Shark Is An Interesting Species Of Shark - Shark Sider

It may come from the strange sucking sounds they make when searching for prey in the sand. As with all sharks, this giant fish is incredibly interesting and very important to the delicate marine ecosystem, especially near fragile coral reefs. They can get quite large with a length of up to 4. These large creatures reach weights as high as kilograms pounds. Typically, they live to between 25 and 35 years of age.

While most fish, including sharks, must keep moving in order to breath, Nurse Sharks can remain motionless while resting on the sea floor by facing against the flow of water and pumping the water through their mouths and gills. As a bottom dweller, they spend much of their time on the sea floor in tropical waters around coastal shelves, reefs, and channels.

This is generally a shallow water fish. During daylight hours, they are seen in groups as large as While in these groups, they mostly remain hidden under submerged ledges and around reefs.

Scientists believe they stay in these groups for protection purposes only with very little dominance or hierarchy. Being bottom dwellers with small mouths, they are unable to consume large fish. They hunt alone and catch their prey from the sea floor, mostly by sucking their prey into their mouths.

The preferred prey includes sea snails, crustaceans, mollusks, and other small fish. In addition, they have been seen grazing for algae and ground corals.

This shark species is Viviparous , meaning eggs develop within the uterus of a female until birth. The pregnancy period usually lasts about 6 months with births occurring generally in the months of June and July.

After birth, an adult female Nurse Shark is unable to produce eggs for 18 months. In average, 30 pups are born at a time. Cannibalism between pups does occur, with the larger and stronger pups eating the underdeveloped ones. When pups are born they are only about 30cm long 12in and have a spotted colored skin. As with Tiger Sharks , they lose the spotted patterns with age.

This species is not typically hunted by commercial fishers or for sport fishing. However, some small operations capture this fish for its skin, which is used in high quality leathers. Their liver is also harvested for certain types of oils. Due to their relatively slow speeds, they are very easy to catch. The threat to humans is very minimal. There have only been a few attacks ever recorded, and only one of those attacks was unprovoked.

No fatal attacks have ever been recorded. Page Created By: Mike Rogers.
