T4. REPRODUCTION SEA HORSE

Amazing! I felt this site as a better option to select the blog so I came here.

I am so much excited after reading your blog. Your blog is very much innovative and much helpful for any industry as well as for person.

As a biology student, I've had my deepest interest on the sea animals and their breeding habits. Seahorses were a rare species and I've had my keen enthusiasm over their living style and fertilisation. Thanks for the video.

I don't know anything about these sea horses and a few species related to them, until I got here and watch the video. Thanks for the share.

It is always wonderful to know more about sea creatures. I am quite surprised to know these interesting facts about sea horses. I could find some similarities with our horses! Keep sharing similar posts about other organisms!

good share

1) What type of reproduction does sea horse have?<br /> It has sexual reproduction<br /> <br /> 2) What fertilisation does the sea horse have? Why?<br /> It has external fertilization because the female releases outside the unfertilised eggs and then the male releases sperm to fertilise them.<br /> <br /> 3) Explain the reproductive process in this animal<br /> The female releases the unfertilised eggs and when its occurs, the male realeases their spermatozoon to fertilised them.<br /> <br /> 4) What embryonic development does the sea horse have? Why?<br /> The &quot;Sea horse&quot; have ovoviviparous embryonic development because the eggs hatches inside the mother´s body.

1) What type of reproduction does sea horse have?<br /> The sea horse has sexual reproduction, because this reproduction requires two parents: a male and a female.<br /> 2) What fertilisation does the sea horse have? Why?<br /> The sea horse has external fertilisation, because the female places over eggs in the male. Finally, the male releases the sperm and later, it expels the eggs.<br /> 3) Explain the reproductive process in this animal.<br /> Seahorses reproduce in an unusual way. The male seahorse becomes pregnant instead of the female.Most seahorse pregnancies lasts approximately 2 to 3 weeks. The males incubate the eggs that are received from the female. Females do not play any parental care after mating. Fertilization and incubation of oocytes received from female takes place in a sac-like brood pouch located under the tail. Male brood pouches in seahorses are the most advanced among all syngnathid species, opening only through an anteromesial pore. The seahorse is sex role reversed. The males exhibit higher levels of behavior patterns and males have the two most overtly aggressive behaviors in courtship, such as tail wrestling and snapping with the snout. Sex role is not synonymous of parental care. The main idea is that male seahorses have a brood pouch which protect, osmoregulate and aerate the eggs in compartments located in the placenta. The fertilized eggs get embedded in the pouch wall and are bathed in a fluid that proves nutrients and oxygen, as well as carefully regulating salinity levels to make sure the embryos develop normally.Gestation usually last only about two to three weeks. Then the males go into “labor”. The young emerge as little replicates of their parents and can feed and defend for themselves. <br /> 4) What embryonic development does the sea horse have? Why?<br /> Sea horses are oviparous, because the eggs stayed in the male´s body before they´re born.

1) What type of reproduction does sea horse have?<br /> It has sexual reproduction.<br /> <br /> 2) What fertilisation does sea horse have? Why?<br /> It has external fertilization. Because the female expels the unfertilised eggs into the brood pouch of the male body. When they are entering the male releases spermatozoa and fertilizes the eggs. <br /> <br /> 3) Explain the reproductive process in this animal.<br /> The female releases the eggs and they enter into the male’s brood pouch. When they are entering the male fertilizes them. The male keeps the eggs during 10 days or 42 days, it can vary, and finally he expels them.<br /> <br /> <br /> 4) What embryonic development does the sea horse have? Why?<br /> It is ovoviviparous, because the eggs hatches into the male’s body until they go out, and this occurs in this kind. The development of the egg occurs in the interior of the male’s body and they doesn’t spend any day out with the egg.

1) What type of reproduction does sea horse have?<br /> - A sea horse has sexual reproduction.<br /> 2) What fertilisation does the sea horse have? Why?<br /> -Sea horse has external fertilisation. Sea horses reproduce through eggs which are carried by the male in a pouch until they hatch.<br /> 3) Explain the reproductive process in this animal<br /> -The eggs are expelled from the body of the female, the female puts them through a tube into a bag on the abdomen of the male.Then, the male fertilise them, by releasing sperm. Eggs remain there until they hatch.<br /> 4) What embryonic development does the sea horse have? Why?<br /> - The embryonics development is ovoviviparous because the eggs remains in the male's body until they birth.

1) What type of reproduction has the sea horse?<br /> The type of reproduction of sea horses is sexual reproduction.<br /> <br /> 2)What fertilisation does the sea horse have? Why?<br /> The fertilisation in external fertilisation.<br /> Because the union of the gametes occurs outside the female´s body. It is typical of aquatic animals, and somo terrestrial ones such as amphibians and some insects.<br /> <br /> 3) Explain the reproductive process in this animal.<br /> Females will lay 250 to 600 eggs inside the males brood sack. After laying the eggs, the female leaves the male as the sole caretaker of the eggs. Immediately after the last egg is laid, the sack is tightly sealed. The eggs inside the sack attach themselves to the male with umbilical cords. After a gestation period of 40 to 50 days, the eggs hatch. The male may be in a state of labor for hours until the young are ready to emerge from the pouch. The babies emerge looking like miniature sea horses and make their way to the surface of the ocean. On the surface of the ocean, they latch onto anything they can find, whether it be a piece of floating sea weed or each other, and they begin to eat. <br /> <br /> 4)What embryonic development does the sea horse have? Why?<br /> It is ovoviviparous. Because the embryo develops inside an egg which remains inside the female´s body until it hatches. In some cases, the egg hatches inside the mother´s body.

1.-They have asexual reproduccion.<br /> 2.-Internal, because the female have a tube to transport the eggs to the male body, the eggs are fertilized when they are transpot to the male body<br /> 3.-I have been explain in the question 2<br /> 4.-Ovoviviparous because the eggs are develop inside the male body

Sea Horses by Ramon Martin Ventas 2ºF<br /> <br /> 1) What type of reproduction does sea horse have?<br /> The Sea Horses has sexual reproduction.<br /> 2) What fertilization does the sea horse have? Why?<br /> It is internal fertilization because the female's put the eggs into the male's sac to fertilize them and hatched.<br /> 3) Explain the reproductive process in this animal.<br /> The female put the eggs in the male sac to fertilize them and hatched, when the eggs break the male spelt them outside. <br /> <br /> 4) What embryonic development does the sea horse have? Why?<br /> The Sea Horses are ovoviviparous, because the eggs are incubate inside the male body.

1) What type of reproduction does sea horse have?<br /> It has sexual reproduction.<br /> <br /> 2) What fertilisation does the sea horse have? Why?<br /> It has external fertilization because the female seahorse places over eggs in the male and the male seahorse releases the sperm and expels the eggs.<br /> <br /> 3) Explain the reproductive process in this animal.<br /> The male seahorse is equipped with a brood pouch on the ventral, or front-facing, side of the tail. When mating, the female seahorse deposits up to 1,500 eggs in the male's pouch. The male carries the eggs for 9 to 45 days until the seahorses emerge fully developed, but very small. Once the seahorses are released into the water, the male's role is done and he offers no further care and often mates again within hours or days during the breeding season.<br /> <br /> 4) What embryonic development does the sea horse have? Why?<br /> It is ovoviviparous because the eggs stayed in the male seahorse´s body until the moment they are born.

1) What type of reproduction does sea horse have?<br /> It has sexual reproduction because this animal requires two parents: a male and a female.<br /> 2) What fertilisation does the sea horse have? Why?<br /> It has a external fertilisation because this is typical of aquatic animals. The female places over eggs in the male. Finally, the male releases the sperm and later, it expels the eggs.<br /> 3) Explain the reproductive process in this animal<br /> 1º- The female seahorse places over 200 eggs through a tube into a pouch in the male´s abdomen.<br /> 2º- The male releases the sperm to fertilise them.<br /> 3º- The eggs hatch inside the male´s body.<br /> 4) What embryonic development does the sea horse have? Why?<br /> This animal is ovoviviparous because the ovoviviparous form inside eggs that are inside the mother, the father in this case. In this uterine way, the shell is broken and the sea horses are born directly.

1)What type of reproduction has the sea horse?<br /> It is evident that as they live in the water, in other words they are alike to small fishes or something like that, they have sexual reproduction.<br /> 2) What fertilisation has the sea horse? Why?<br /> The fertilisation is external because the female expells the eggs from the inside of her bodyan then the male fertilises it outside.<br /> 3)Explain the reproductive process in this animal?<br /> The eggs are expelled out of the female's body and the male releases the huge quantity of spermatozoons which are supposed to fertilise the eggs. After the fertilisation, the male seahorse incubates the eggs until they hatch and are expelled outside the body.<br /> 4)What embryonic development has the sea horse? Why?<br /> It is ovoviviparous because the eggs hatch inside the male's body and when expell they don't release any egg, at least in this video.

1) What type of reproduction has the sea horse?<br /> The sea horse or hippocampus are small fishes, so they have sexual reproduction.<br /> <br /> 2) What fertilisation has the sea horse? Why?<br /> The sea horses have external fertilisation because the female expels the eggs from his body to the male sac. The female deposits around 1000-1500 eggs in the sac of the male. And this process lasts just 6 seconds. There in the male sac, the male kick out spermatozoons to ferilize the eggs. And finally the male carries the eggs from 9-45 days until the sea horses emerge ( and obviously all this happens out the body of the female)<br /> <br /> 3) Explain the reproductive process in this animal?<br /> The female expels the eggs from his body to the male sac. There the male kick out spermatozoons to fertilize the eggs. And he carries the eggs until their emerge.<br /> <br /> 4) What embryonic development has the sea horse? Why?<br /> The sea horses have ovoviviparous embryonic development because the eggs hatch in the moment when they emerge from the father body.

1) What type of reproduction has the sea horse?<br /> It has sexual reproduction.<br /> 2) What fertilisation has the sea horse? Why?<br /> It has external fertilisation because the female realese the eggs into the male´s sac to be hatched(para ser incubados). While this is happening the male releases esperamtozoons which fertilize the eggs.All of this occurs outside female´s body.<br /> <br /> 3) Explain the reproductive process in this animal?<br /> The female realese the eggs into the male´s sac to be hatched(para ser incubados).
