The deep sea anglerfish is one of about 200 species of anglerfish that are currently living in the deep oceans today (Animals Time). The definition of the word “anglerfish” means a fish having a large mouth with a long filament for luring prey. A synonym of the word anglerfish is goosefish (Dictionary). The scientific name is Melanocetus johnsoni (Seasky). The deep sea anglerfish belongs to the class of Lophiiformes (Animals Time). The deep sea anglerfish also has a nickname which is known as the common black devil because of how it looks. Due to its dark skin color, and its scary looks and sharp ferocious teeth it has been seen as a mysterious sea creature (Seasky).
The deep sea anglerfish have very small eyes (Seasky). The color of the anglerfish can be a deep black, a dark shade of grey, or a dark brown (Buzzle). The anglerfish’s skin is very fragile and sensitive. If a person even touches it, the skin might fall off from the anglerfish (Deep Sea Creatures). The deep sea anglerfish is shaped like a basketball (National Geographic) and is not able to swim well due to its body shape (Frogfish). The female anglerfish body size ranges from about three inches to about a foot long, but there have been some larger female anglerfish that are about three feet long. The male anglerfish is a tiny dwarf compared to the female in terms of size. The male anglerfish is about as big as a small human pinky finger. It is hard to find many mature anglerfish in the deep ocean because both male and female anglerfish reach sexual maturity quite late in their lives (Bioexpedition).
The esca of the anglerfish is the body part of the anglerfish that waves around in front of its head to attract prey. The "rod" is the part of the esca which is attached...

...e it never eats (Its Nature).
2) The esca is connected to the female anglerfish's mouth nerves, so fish or other sea creatures near the photophore will get eaten (Odd Animals).
3) The prey usually gets eaten within a fraction of a second. (Odd Animals).
4) When the female anglerfish want to lay eggs, it can trigger sperm in the parasitic males’ bodies. 5) Most of the anglerfish larvae won’t live to become mature because of all the predators out there (Bioexpedition).
6) A group of anglerfish, like other kinds of fish, are called a school (Animals Time).
7) The name of the anglerfish comes from the esca on the female anglerfish top (Its Nature).
8) The male has to find a female to mate with or he will die (Its Nature).
9) Anglerfish also can sense where prey is coming from using hair cells (Frogfish).
10) The lifespan of the anglerfish is up to 24 years (Gwinnett).
The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature for breeding is about room temperature it can be inferred that the A. franciscana will prefer this over other temperatures (Al Dhaheri and Drew, 2003). This is much the same in regards to acidity as Artemia franciscana, in general thrive in saline lakes, can survive pH ranges between 7 and 10 with 8 being ideal for cysts(eggs) to hatch (Al Dhaheri and Drew, 2003). Based on this fact alone the tested A. franciscana should show preference to higher pH levels. In nature A. franciscana feed by scraping food, such as algae, of rocks and can be classified as a bottom feeder; with this said, A. franciscana are usually located in shallow waters. In respect to the preference of light intensity, A. franciscana can be hypothesized to respond to light erratically (Fox, 2001; Al Dhaheri and Drew, 2003). Using these predictions, and the results of the experimentation on the A. franciscana and stimuli, we will be able to determine their preference towards light, temperature, and pH.
Because of its size and abundance, T. californicus is commonly regarded as the insect of the sea. This creature is generally very small, from 1-3 mm in size as adults. They are cylindrically shaped, and have a segmented body (head, thorax, abdomen) though no noticeable division between body regions (Powlik 1966). Each segment of the body has a pair of legs. They use their 'legs' to propel themselves through the water in short rapid jerks. They have 2 pairs of long feathered antennae, a chitin us exoskeleton and a single eye in the middle of their head, this simple eye can only differentiate between light and dark.
The latter is probably a reference to the fish's snout.
A defining feature of the lionfish which everyone sees are the “18 venomous spines on its dorsal fin and its pelvic and anal fins, which are used for defense” as described in FACE OFF WITH THE ENEMY: LIONFISH by Special To The Citizen. Which is a neurotoxin that results in intense pain and swelling of one’s body. Fernando Simal, a marine hunter at STINAPA National Marine Park, found out the potency of their venom after his first hunt when being stung by the lionfish he caug...
The Narwhal, Monodon monoceros, is a social, specialized deep-water marine mammal characterized by a unique tooth growth protruding from the upper jaw. Narwhals lives along the coasts and rivers throughout the Arctic,characterized by icy ocean temperatures. Narwhals are usually found in groups of 15 to 20, but herds of several thousand have been seen in the Arctic waters since 1871. Regularly found eastwards from the Canadian Arctic to central Russia they have also been distributed throughout the Eurasian Arctic and in an especially high abundance around the oceans west of Cape Farewell on the east coast of Greenland in the summers and during the winter primarily in the Baffian Bay, and in the Canadian archipelago in the springtime (Reeves, Tracey). The Narwhal has two teeth, located in the upper jaw, however only the left tooth usually develops leaving the underdeveloped right tooth in males and typically both teeth in females vestigial (Das). The protruding tusk grows to about 3 meters forward in a counterclockwise spiral pattern (Drury). The distal end of the tusk appears polished, with the remainder commonly covered by a growth of algae. There is an outer layer of cement, an inner layer of dentine, and a pulp cavity that is rich in blood (Reeves, Tracey). The Narwhal’s head and body ranges from 3-6 meters, with the pectoral fin being around 30-40 cm, and the tail flukes expanding over one meter (Reeves, Tracey). The males are typically larger in size than the females averaging about 3,500 pounds in males and 1,000 in females (Drury). Their bodies begin as an uneven grayish hue and as they mature darken to a mottled bluish black color, darker above than below (Reeves, Tracey). Narwhals posses relatively small heads, a blunt sno...
The Longnose Gar and Mudpuppy are both native species that can be found in Ohio. The Gar gets its name from the long nose that is very similar looking to a beak of a bird. The Gar in the lab is brownish grey with black spots, but in the wild they do have a range of colors. Their size is often a wide range as well. Some Longnose Gars can grow to be up to 6ft, but it is common for them to be between 3 and 4 feet long (Groves ). The gar in this lab is about a foot long, so smaller than those in the wild. The other animal in the tank is the mudpuppy. Mudpuppies are common all over the northeast United States. They are also called the waterdog which is because they are the only salamander that makes noise (National geographic: Mudpuppy). They mainly stay at the bottom of the lakes and body of water where they feed. Both the mudpuppy and the Longnose gar’s conservation status are common.
Distinctively visual language and cinematic techniques highlight to the responder the particular literal and metaphorical experiences characters are faced with, within a text. Peter Goldsworthy’s novel Maestro, Don McLean’s song ‘Vincent’ and the intriguing film Australia by Baz Luhrrman, explore the ways in which the human experiences of an individual’s connection to landscape is fundamental in shaping one’s sense of identity, personal growth and development. Composers further explore the realisation that our lives can be enriched by an understanding and appreciation of art as well as a deeper understanding of the importance of love and lust. The depiction of characters is conveyed through distinctively visual images to highlight the subsequent development of courage and resilience leads responders to a deeper understanding of how human experiences can create a sense of individuality.
Though food is everlasting in both the coral reef and deep sea, space is very limited. Organisms in both habitats have to compete for space and survival, having defense mechanisms to keep other species from killing out their kind. Some fishes in the coral reef hide in cracks and crevices along the rocks and corals to hide from their predators. Other fishes camouflage within the brightly colored corals to hide from predators, or even humans looking into their tank. The deep sea holds many small fish, but with large mouths. The large mouths and pointy teeth help the miniscule fish eat their prey, whi...
During the 18th and 19th centuries, the Irish rapidly flowed into the United States. The Irish immigrated in different waves and for various reasons, only to be greeted with significant barriers when landing in America. The Irish were essentially pushed out of Ireland because of the awful economy and the great potato famine. Upon arriving in the United States, the Irish had a difficult time with jobs, discrimination, housing, and money in the populated urban cities in which they settled. Having a rough life in the New World, the Irish still managed to leave a powerful legacy and an influence still visible today.
In order to understand the present lifestyles relating to different approaches and tactics applied by humans in mate choice preferences, there is the need to refer to Darwin (1859, 1871) evolutionary perspectives. Darwin (1871) sexual selection is the driving force for males and females reproductive quest for their genes survival. These driving forces have been classified into two categories as intra-sexual and intersexual mate selection.Intersexual selection is male sexual selection process whereby males compete with other males and the females choose the strongest as their ideal partner. Intra-sexual selection occurs when the male species fight among themselves and the strongest gain access to females for
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
From the surface to its deepest depth the ocean is 11km deep, and with this distance comes a vast change in physiological feature of fish as they try to survive the changing conditions.
In general, electroreceptive fishes are categorized into non-electric fishes and electric fishes (Crampton & Albert, 2005). On the one hand, non-electric fish do not possess electric organs and use passive electroreception, which is when the fish reacts to external electric stimuli (2005). On the other hand, electric fish are fishes that have specialized electric organs (electrosensory organs) present and use active electroreception, which produce or generate electrical stimuli (2005). The receptors that electric or non-electric fishes use to detect the electrical stimuli are called pit organs that are often open to the surrounding water by way of canals that are filled with an electrically conductive gelatinous substance (2005). There are two types of pit organs: tuberous electroreceptive organ, which are used in active electroreception, and ampullary electroreceptive organ, which is used in passive electroreception.
Everyone is a part of a community. Most people are a part of multiple communities. A community is a group of people that have a commonality. Sometimes it is based on where you live, hobbies, goals, etc. I believe that communities are created unconsciously and are connected to someone’s identity, especially when a person is considered a part of multiple communities. Sometimes, a person may connect very well with their community. Sometimes, a person may feel very distant from their community. In the movie, “English Vinglish”, the main character, Sashi, shows examples on how communities are created through commonalities, and the acculturation theory. Sashi was a part of multiple communities. A few communities included her, her Daughter’s school,
