Some vertebrate species have the ability to reproduce asexually even though they normally reproduce sexually. These include certain sharks, turkeys, Komodo dragons, snakes and rays. However, most reports have been in females who have never had male partners.

How do stingrays reproduce?
Freshwater stingrays reproduce through internal fertilization. A male impregnates the female by using a modified pelvic fin as he bites the female's back. The unborn young are ovoviviparous, meaning they are nourished by egg yolk inside the mother's body.
What animals do asexual reproduction?
Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts.
What organisms are both sexual and asexual?
Asexual versus Sexual Reproduction
Many organisms can reproduce sexually as well as asexually. Aphids, slime molds, sea anemones, and some species of starfish are examples of animal species with this ability.
How long do stingrays stay pregnant?
The yolk provides the nourishment they need, and when this is depleted, they begin feeding off their mother's milk. The gestation period of stingrays is not set; research has shown some pregnancies that last for 125 days and others that last for 226 days. The mean length of gestation is 175 days.
How do Southern stingrays reproduce?
Like in most whiptail stingrays, the southern stingray's tail is very long, often longer than the body width. This species reproduces via internal fertilization and gives live birth. However, southern stingrays do not connect to their young through a placenta, like in most mammals.
Are snakes asexual?
Are Snakes Sexual or Asexual? A majority of snakes are born from sexual reproduction. Sexual reproduction means that two parents mate with each other. The male uses his hemipenes in order to fertilize the female eggs.
Are bees asexual?
Most animals reproduce sexually, which means that both males and females are required for the species to survive. ... In the Cape bee, female worker bees are able to reproduce asexually: they lay eggs that are essentially fertilised by their own DNA, which develop into new worker bees.
Are sharks asexual?
Where do the babies come from? In sharks, asexual reproduction usually happens via a process called "automictic parthenogenesis," explained Feldheim. During egg development, one egg is produced along with three other products called polar bodies. Usually these polar bodies are simply reabsorbed by the female.
Are fish asexual?
The fish reproduces using a strategy in which a female's egg cell develops into a baby without being fertilized by a male's sperm cell. But that does not mean the fish does not need some hanky panky. ... About 50 vertebrates are known to use asexual reproduction including fish, amphibians and reptiles.
Are lizards asexual?
It's a genetic-diversity advantage that today's females still enjoy and propagate. Without females, lizards in the Aspidoscelis genus, like this New Mexico Whiptail (Aspidoscelis neomexicana), reproduce asexually. Unlike other animals that produce this way, however, their DNA changes from generation to generation.
Are snails asexual?
Different snails reproduce differently, but most snails are "hermaphrodites." Being a hermaphrodite means that any given snail can be both male and female at the same time. ... Some hermaphrodite snails do not need another snail to reproduce, but can make more snails all by themselves (this is called asexual reproduction).
Do stingrays have teeth?
Stingrays don't have teeth like we do. They have dental plates with rows of small, flat teeth. Much like sharks, rays replace their teeth.
Do stingrays stay with their mom?
After birth, most juvenile stingrays swim away to start their lives away from their parents. In some species, such as the freshwater whipray (Himantura chaophraya), the mother cares for her young by having them swim with her until they are around one-third of her size.
Are stingrays friendly?
STINGRAYS AREN'T NORMALLY AGGRESSIVE.
While a run-in with a stingray has the potential to be deadly, they normally act kind and gentle around humans.
How does the stingray attract a mate?
McCourt, R.M. & A.N. Kerstitch. 1980. Mating behavior and sexual dimorphism in dentition in the stingray Urolophus concentricus from the Gulf of California.
Do sting rays have Claspers?
Male rays and skates (as well as sharks) have claspers, while females do not. Claspers are modifications of the pelvic fins and located on the inner margin of the pelvic fins.
What's the difference between a mantaray and a stingray?
Both have flattened body shapes and wide pectoral fins that are fused to the head. One of the biggest differences between manta rays and stingrays is that manta rays do NOT have a tail "stinger" or barb like stingrays. ... Stingrays dwell on the ocean bottom, but manta rays live in the open ocean.
