Reproduction; Ecological Importance; Lemon Shark: Negaprion Brevirostris. The Sandtiger shark (Carcharias taurus) is another species that practices intra-uterine cannibalism. Examples of species using this method of reproduction include: Great white sharks (Carcharhinus carcaradon), Pelagic thresher (Alopias pelagicus), Nurse Sharks ( Ginglymostoma cirratum) and the Greenland shark (Somniosus microcephalus). Unlike bony fish, who shed eggs and sperm into the water column, sharks have developed internal fertilization as a mode of reproduction. In the early stages, the embryo receives nourishment from a yolk sac, once this is used up the sac attaches to the wall of the uterus and forms a placenta. Once they are mature, sharks will usually mate in the spring and summer. The number of pups in the litter ranges from 2-20. The protective egg capsules are composed of two to three cases and often have interesting shapes, e.g. The Lemon Shark, also known as the Negaprion Brevirostris, is the best known and most researched of all sharks. Often feeding at night, these sharks use electroreceptors to find their main source of prey: fish. The period of gestation can be anything from 9 months to 2 years. In many aspects it resembles the reproductive method of mammals. The lemon shark is a species of shark from the family Carcharhinidae. Lemon Sharks in reproduction are viviparous (refers to development of the embryo inside the body of the mother eventually leading to live birth.) For other species, the energy reserves present in the egg are supplemented by additional nutrients from the mother during gestation, this is referred to as matrotrophic. The vast majority of animals weigh around 200 lbs. Almost 70% of the sharks living today have developed a method to care for their brood inside the female's body. Examples of species using this method of reproduction include: Bulll sharks (Carcharhinus leucas), Lemon sharks (Negaprion brevirostris), Blue shark (Prionace glauca) and the Hammerhead sharks Sphyrnidae. The pup will continue to receive nourishment directly from the mother’s bloodstream and waste products will be transferred to the mother for elimination. How do sharks reproduce? They also have a large yolk which nurtures the embryos sufficiently with nutrients. Examples of species using this method of reproduction include: Zebra shark (Stegostoma fasciatum),  Swellshark (Cephaloscyllium ventriosum), Epaulete (Hemiscyllim ocellatum) and Hornshark (Heterodontus francisci). Examples of species using this method of reproduction include: Bulll sharks (Carcharhinus leucas), Lemon sharks (Negaprion brevirostris), Blue shark (Prionace glauca) and the Hammerhead sharks Sphyrnidae. The certain species is Negaprion Brevirostris. Approximately 30% of all sharks lay eggs. Mating is difficult to observe in the wild, and most sharks will not mate in captivity making it very difficult to study mating habits of sharks. cordlike growths which serve to anchor the eggs on water plants or other objects. © 2020 - 2020 Shark Foundation / Hai-Stiftung. In this website presentation you will find the classifications, adaptations, diets, colorization, habitat, and many more of the well know Lemon Shark. Aplacental Viviparity (Ovoviviparous) –The embryos will develop within an egg, which will hatch inside the female’s body. The eggs are fertilized in the upper part of the fallopian tube and are encased in only a very thin membrane. This form of reproduction is considered a primitive form and is common in more bottom dwelling (benthic) species. Illustration: Viviparous shark - the birth of a lemon shark pup. There is a lack of adequate research to show the overall mating rituals and process for the Lemon Shark. Nutrients are provided from several sources. The female shark deposits egg cases somewhere safe to protect them from being eaten by predators. Like whale and humans, Sharks are k/selected species, which means they adhere to a life history strategy of slow growth, late maturation, long gestation and the production of small litters of high quality pups who are born ready to evade predators and competitors enhancing their survival rate.

Lemon sharks enjoy the many benefits of group living such as enhanced com… Oviparity –Oviparous sharks lay eggs, which are protected by an egg case, these are referred to as “mermaid’s purses”. The females then retain the developing eggs in the last extended section of the fallopian tube which is thus termed the womb or uterus. Protected by the mother's body, the pups develop and are born as self-sufficient sharks following a gestation period of 6 to 22 months.
