Terms of Reference Background Seahorses are an iconic, shy species that have become adapted to live in a variety of habitats. They have the ability to camouflage and a prehensile tail that can only be forcibly unlocked in the most extremes of weather. They have the ability to grow and reabsorb spiny appendages on their body, depending on the habitat they live in. The seahorse male is the only male animal in the world to have a true, full pregnancy. There are two species of Seahorse in the British Isles, the spiny seahorse (Hippocampus guttulatus) and the short snouted seahorse (Hippocampus hippocampus); both widely distributed and both specialising in differing habitats due to subtle differences in the shape of the snout and body and their dietary needs, although they can also be occasionally found in the same habitat together (Garrick-Maidment 2004). Seahorses are typically found in pairs, once they have migrated back into shallow waters from their deeper, winter refuge. They are normally observed in shallower water of 2 meter (m) as the sea temperature warms up to 9 ºC or more (Garrick-Maidment, 2013), they then form …show more content…
To present the data and undertake statistical analysis to determine and produce maps of ‘preferred seahorse habitat’. For example, percentage of sightings per habitats in the case of non quantitative data, mainly for this seahorses sighting database (presence and absence). Since the analysis of presence- only data is a problem in determining the species distribution and accurately determining population sizes, more exploratory analysis and investigation of selected sites will be undertaken to see why some of the preferred habitats have no records of sightings (lack of survey, under-reporting or poor environmental condition, for example). Hence, logistic regression for presence and absence is one option while Generalised linear model (GLM) prediction using regression analysis is another alternative for continuous data (such as sightings
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
Monitoring of the species is vital in determining the next course of action for the conservation of this species. However, the monitoring is opportunistic at best (“Grey Nurse Shark Watch”). Further funding is required in order to accurately and efficiently monitor the population and movement of the Grey Nurse Shark. The information received thus far is not conclusive as to whether the population is recovering, indicating there is a need for expanded conservation
Bottlenose Dolphins are a very interesting animal. They have a fusiform (Spindle shaped) body that allows them to move quickly in the water. Because of the Dolphins’ shape they have bilateral symmetry. They also have a dorsal fin, flippers, and a fluke. However, Bottlenose Dolphins do not have ears on the outside of their bodies, hair, or hind limbs. The color of this type of dolphin is usually a light grey color to a black. Their stomach is white and sometimes has a pink hue. One physical adaptation these dolphins have is a telescoped skull. The skull is like this because it allows them to breathe more easily while swimming. Bottlenose Dolphins also have blubber that they use as insulation and vascular shunts that allow them to have cooling for certain types of organs and tissues in their bodies. Finally, Bottlenose Dolphins have sharp teeth that let them grasp onto their prey, so their tongue can push the prey down the dolphin’s throat. Bottlenose Dolphins have a range mass of 260 to 500kg which is 572.69 to 1101.32 in pounds. The average mass of the Bottlenose Dolphin is 400kg. Their average mass in pounds is 881.06.
Steller sea lion pups possess thick rough coats with a mostly dark appearance. After the first molt, their color lightens. The complexion of female and male Steller sea lions is a golden-brown to a reddish brown. They have a somewhat darker shade in their chest and abdomen. Steller sea lions also display sexual dimorphism which means that the males are remarkably larger than females. Similar to all pinnipeds, the Steller sea lions have whiskers to sense prey. They also molt every year which parallels to other pinnipeds, and they are mainly insulated by blubber. In addition, they have flippers that are used for locomotion. Their sensory organs are accommodated to operate both underwater and in the air, but because they are mammals they have to come up to the surface in order to breathe.
The first thing is the ability to camouflage. Sea horses being able to camouflage is a very great way to survive in their habitats because they can hide from anything that tries to harm them. In source 1 paragraph 3 sentences 1 through 3 it states “(1)
Did you know that seahorses are the only members of the Hippocampus species? The name Hippocampus is Greek, it means “Horse Sea Monster.” There are thirty-four different species of seahorses. Many people are surprised when they find out that seahorses are a type of fish. They have fins and gills, the defining features of a fish. When seahorses are in a group they are called a herd, just like horses. Seahorses usually live one to five years, but they are becoming endangered because their habitat is slowly being destroyed. “Seahorses can be as small as one inch long and as tall as twelve inches long!”(Trisha Shaskan, page 23) Seahorses are not alone though, the Syngnathidae family also includes pipefish and seadragons. Syngnathidae means fused jaw.
The Man in the Yellow Suit “Run!” Toni yelled as a yellow bus turned the corner. “Why it's just a bus? ” said Jack well everyone else darted for the house. “No Jack!
Seahorses are a bizarre species, and one almost tends to forget they are fish.This member of the Hippocampus genus has quite a few bizarre characteristics; they range between an inch and a foot in length, carry a curved tail, a tube-like mouth and bony plates on their skin which provide protection.
Species of animals use morphological and physical adaptations to evaluate the environment around them for a variety of reasons to continue with daily life. Morphological characteristics can aid navigating a certain habitat which is essential for survival. Marine mammals might exhibit characteristics in order to successfully maneuver through oceanic waters, which are often plagued by low visibility and turbid waters. Pinnipeds serve as an example of species that live and hunt in drastic waters. Pinnipeds exhibit a physical characteristic known as vibrissae, a sensitive sensory hair or whisker. Vibrissae of a pinniped can be shown in two forms: smooth and undulated. Undulated vibrissae, structures that are wavy or bumpy in form, are present in most true seals with the exception of the monk and bearded seals. Other pinnipeds, such as sea lions, fur seals, and walruses, have smooth vibrissae structures. Careful examination of the vibrissal system and structures reveal that they are highly sensitive to outside stimulation.
The Orectolobus arctoae or more commonly known as the Arctic Wobbegong, just like every other reproducing organism on this planet, goes through a process called natural selection. One adaptation of this particular organism is the ability to camouflage to the sand of the Arctic Ocean with lighter colored flesh [in comparison to its nimble yet sluggish cousin the Japanese Wobbegong]. The genetic variations of this adaptation are flesh tones that are the same color of, lighter or darker than the sand of the Arctic Ocean; which is uniquely lighter than that of the Indo-Pacific. The O. arctoae overproduces its offspring with one every two years. With a gestation period of 1 year and a lifespan of approximately 50 years, this organism produces 25 pups over its lifetime. The limiting factors in the environment of the Arctic Ocean that cause this adaptation are the threat of multiple species of large whales and other predators. In the process of selection, the Wobbegongs whose flesh is closer to the color of the sand are able to survive and reproduce viable offspring. Another adaptation of the Arctic Wobbegong is the layer of blubber under the dermis found in many Arctic organisms. The genetic variations of this adaptation are blubber depths that are thicker or thinner than the approximate 6 inches. The O. arctoae overproduces its offspring with one every two years. With a gestation period of 1 year and a lifespan of approximately 50 years, this organism produces 25 pups over its
Duality is the ghost of man. It haunts man in unperceivable matters such as the right and left brain (Melina par 1). Although duality may not make complete monsters out of humans, as seen in Mary Shelley’s “Frankenstein”, which is the first science fiction work (Stableford par 7), it can still summon unimaginable evils from within us all. This is especially seen in the Gothic and fictitious novella known as Robert Louis Stevenson’s “The Strange Case of Dr. Jekyll and Mr. Hyde.” This book contrast his previous works such as Treasure Island, an adventure tale (Robert Louis Stevenson par 9); however, “The Strange Case of Dr. Jekyll and Mr. Hyde” is also an adventure tale in its own right.
When people hear about the Code of Hammurabi they tend to think of an Eye for an Eye. This is the same with the Beatitude and the Ten Commandments, except they think of Moses and Christianity. What people don’t realize is that these three objects/laws are really close to each other. They do have their differences. This will explain the differences and similarities of all three.
Limpets (Patella vulgate) live in algae rich environments on rocky shores. . It has been proposed that in more sheltered areas, limpet shells will grow to be flatter with a larger diameter, while in more exposed areas of coastline, they will grow a taller and narrower shell shape. To find out whether or not the shores of Aberdeen reflected this, samples were taken from two sites (Site A and Site B) along the Aberdeen coastline that varied in their exposure to wave action. The sites were chosen to provide two sample sites with a notable difference in their environment. In the more sheltered site A, limpets were not exposed to harsh waves, while at site B, there was significantly more wave action. Quadrats were used at both sites to provide an area of sampling for the limpets and they were placed around 5 meters from the waterline. The overall results from the study showed that there is a very strong relationship between diameter and height in Limpet shells and that there was an incredibly slight difference in the relationship between the two sites.
Sea Horses have better survival habitat because they can change colors to any color there around and stay hidden where nothing can see it and they are very sneaky because their small and camouflage to whatever is around, they might not be fast but they have a better advantage because they are small and they could swim into something small to make where the big fish can't get the sea horse and also they could just hide in the grass and just be quit and lurk around and get there food and have a good
