The Birth of a Seahorse
Deep down in the dark blue sea, male pregnancies are not extraordinary. Believe it or not female seahorses are actually the ones that impregnate the males. The reproductive process starts off by the male and female meeting up and “dancing”. One can think of this as being the first date. The two will continue to meet and swim together along with intertwining their tails several days before actually mating. The fish will also grip a strand of sea grass and whirl around it in unison. This kind of dancing and courtship synchronizes the movements of the seahorses and prepares the male to receive the eggs when the female is ready to deposit them (Maia, et al. 2013).

Over the years sea horses have adapted to their environments very well so far. They're good at catching their food and keeping quiet while doing it. Especially with their camouflage skills. All they have to do is stay still, stay in camouflage, wait for the bait, and then jump out and take it. So, sea horses have adapted quite well.
Shark mating rituals vary from the size of the shark and its specie. In smaller, more flexible species, the male coils around the female, while the male of the larger specie orients himself parallel and head-to-head with the female (Woums & Demski 1993). Some species mating rituals also consists of males biting females on the pectoral fins or the middle of the back to hold on to them (Woums & Demski 1993). The female will often bear scars or marks, after the ordeal. Due to the fact that sharks are cold blooded animals, there is no precise gestation time. The development of the embryo will depend solely on the temperature of the water, however, the gestation period can last anywhere from 2 months to 2 years (Woums & Demski 1993). Within shark species there are two methods of reproduction. In some cases a female shark will lay eggs in a coastal nursery where the presence of other sharks are absent. And in other cases, usually in the larger sharks, females give birth to live offspring (Wourms & Demski 1993). In which case the young are born fully developed, and once they are born they shoot away fast or they risk being eaten.
Throughout history, humans have depended on the horse. Horses have contributed to the growth of humankind as transportation, farm workers, and battle steeds. They have been trained to support humans in many ways. When did this relationship begin? At what point did the horse become a vital part of human society? Exploring the evolution of the horse can help to answer these questions.
The word "draft" originally comes from "draught," an old word that means "to pull something." From early plows to carriages to fire trucks, draft horses have pulled them all. Without strong draft horse breeds, this country wouldn't have been built. The original work horse plowed the farms, provided transportation and helped to build the great American railroads. With the onset of the automobile, the number of draft horse breeds in the U.S. rapidly declined, but the proud work horse is enjoying resurgence and making a comeback.
In Pink Sheep’s house, Homie Dolphin was playing video games and eating burritos and Mountain Dew. When these two guys were too focused on the games a hater broke in the house and took their supplies to burritos and Mountain Dew. On his way out he took Homie Dolphin’s gold necklace worth a trillion dollars.
Sea minks are now extinct but were once ranged from Casco Bay, Maine in the south to as far north as New Brunswick, Canada. Their main habitats are coastal regions. Sea minks are usually confused with the American mink, but the sea mink is bigger. Sea minks are on average 914mm but the American mink is 580-700mm, so there is a good difference in size. Also the male sea minks are larger in size compared to the females. Their fur is a reddish dark brown, and it is not known if their fur changes during the summer and winter.
At this point in time, it is getting harder and harder for a man to surprise the love of his life with an engagement ring and the word, “Will you marry me?” Countless men have gotten on bended knee on the beach, at a football game, cruise ship, and the spot where they met their partner.
“Can you imagine being in a small concrete enclosure for your life when you’re used to swimming 100 miles a day?” This is how captive dolphins live everyday, their natural habitat is swimming miles and miles in the ocean. When they get captured their lives change for the worse. In the past decade Seaworld and captive animals has been a controversial subject. Many people believe the keeping orca whales captive is damaging to the animal and affects them in a negative way. Others believe Seaworld is used to rescue animals and save them. The treatment of animals in captivity is cruel and should be stopped. Keeping animals captive is an appalling punishment.
Animal captivity acts as a broad way for the public to view and enjoy wild species. However, “it transforms helpless, harmless animals into aggressive, agitated monsters” (4). “Wild animals should never be kept in captivity- especially not at SeaWorld Parks” (7), and little did you know that kept Animals in captivity are deprived of their loved ones, their freedom, and their personal will to carry on, which lead to them becoming highly aggressive. The conditions in captivity are horrifying and disgusting. The animals have to have a better place to live in so that they will have the capability of striving. Why do you think so many species are in danger of going extinct? Many believe that SeaWorld is a family-friendly incorporation and an
The sea mink (Neovison macrodon) was a mammal from the eastern coast of North America, in the family of weasels and otters in the order Carnivora. The largest of the minks, it was hunted to extinction by fur traders before 1903, when it was first given a species description. Some biologists classify it as a subspecies of the American mink. Estimates of its size are speculative, based largely on skull fragments recovered from Native American shell middens, and on tooth remains. Some information on its appearance and habits was provided by fur traders and Native Americans. It may have been similar in behavior to the American mink: it probably maintained home ranges, was polygynandrous, and had a similar diet, supplemented by saltwater prey. Sea
A Marine Biologist Will be a Right Careen Scientist for You ! Marine biologist are scientist that study water bodies, performing a number of duties that vary by the specific job. They may research experiment or create plans for action to improve and sustain aquatic life, healthy, and productive. Marine biologist spend many hours in oceans, lakes and rivers studying plants and animals, in addition to the time spent in the classroom learning about the sciences applicable to marine biology. Marine scientist study and analyze ocean ecology and aquatic life.
espite their small size, sea dragons are carnivorous animals and therefore have a purely meat-based diet. The sea dragon uses its pipe-like snout to suck its prey into its oddly tooth-less mouth. Sea dragons hunt crustaceans, plankton, shrimp and even small fish, using their camouflage to their advantage. Sea dragons have numerous natural predators in the south and western coastal waters of Australia but are rarely even spotted to the elaborate camouflage of the sea dragon. Those few sea dragons that are unlucky enough to be found, are usually spotted by large fish. As with sea horses, it is the male sea dragon who care for the eggs once they have been laid by the female. The female lays around 250 eggs onto the long tail of the male sea horse.
In the article, “How a Seahorse Dad is like a Pregnant Woman” by Sarah Zielinski, may sound comical, but much to my surprise, has some biological information that is worth reading. Unlike human, beings male seahorses carry the babies, instead of the women. A male seahorse carries the eggs of his mate in a pouch. Inside the male is where the eggs become fertile and start the growing process. The pouch, or the homes of the eggs are inside the male, around the stomach region. The male’s pouch is very adaptable. When the male is not pregnant the pouch is not sealed off, but when there are eggs in the pouch it becomes sealed, isolated from anything else. When eggs occupy the pouch it adapts its size and the nutrients it realizes according to the
Clownfish have interesting mating behaviors. For instance, they are hermaphrodites meaning they have both female and male genitalia. There is strict dominance hierarchy in a group of clownfish. Two clownfish, with the female being the biggest, reproduce through external fertilization. However, if the female was to die, the male would become the high female and the next largest male would become the highest male and reproduce with the clownfish who became female. Throughout this monogamous relationship, they can mate all year long. A female clownfish can lay 600-1600 eggs. While breeding, the male cleans debris and creates a nesting area with his mouth.
Clown fish are incredible creatures from their origin, to the way they reproduce. They are one of the most unique fish ever to be researched. The clown fish, also known as the anemonefish because of the close relationship they have with anemone, is a small fish that is found around tropical coral reefs in saltwater. Clown fish can grow to be from 2 to 5 inches long, while the males tend to be significantly smaller than the females. The most commonly known species is orange with white markings.
