Angler Fish Research Paper

The ocean is a very difficult place to live. The animals living in the seas have to handle every moment with finding food, and protecting themselves from predators. There are many ways of hiding, defending, and feeding, and every different technique has advantages for different animals. Adaptations for Survival in the Sea explores some of the adaptations used by various sea creatures to survive.

Do you know what it's like to spend a good amount of time trout fishing and not consistently catch large trout? Many people have this problem. In this article I'm going to outline some tips and techniques that will help you take your trout angling to the next level. So, why am I someone who knows anything about advanced trout fishing techniques? There are two simple reasons.

The smalltooth sawfish Pristis pectinata (Latham 1794) species are a large batoid elasmobranch that prefers very specific habitats (Simpfendorfer et al., 2010). They are also a K-selected species, which means that the smalltooth have a late maturity, a small pup size and a slow growth rate (Seitz & Poulakis, 2006). The smalltooth sawfish species can be identified from the undefined or undeveloped lower caudal fin (Gómez-Rodríguez et al., 2014). Another identifier is the first dorsal fin is in line with the beginning of the pelvic fin (Gómez-Rodríguez et al., 2014). Unlike the other sawfish, the P. pectinata have about 20 to 34 rostral teeth on the saw, which is more than most species (Gómez-Rodríguez et al., 2014).

If we are in deep waters we stay near the surface. We live in warm tropical waters in the Atlantic, Indian, and Pacific oceans. We mostly eat sponges, anemones, squid, shrimp, and of course, jellyfish!

The Pacific Lamprey (Entosphenus tridentatus) is an anadromous species that is found along the west coast of North America, primarily along the coast of Washington, Oregon, and northern California. E. tridentatus is a semelparous species that can live up to five years and can spend up to three and a half years in saltwater. They begin metamorphosis in July and the known period of entry into salt water is from December until June. In the ocean E. tridentatus have been documented to primarily feed on Pacific Salmon species such as Chinook (Oncorhynchus tshawytscha), Coho (Oncorhynchus kisutch), Sockeye (Oncorhynchus nerka), and Pink (Oncorhynchus gorbuscha). O. tshawytscha have endured most lamprey attacks because researchers believe that E. tridentatus attack this salmon when it is making the transition to swim back up stream to spawn. E. tridentatus who do not represent an anadromous life style also prey heavily on resident salmonid species. Salmonid species have an important role in the diet and life history of E. tridentatus as they are an important prey item.

Adaptations: A long snout to catch prey, and a long curly tail to grab coral and sea grass due to high current pressure.

The ocean is one of, if not, the largest biome on earth. There are more than one million species of marine life. Covering over 70 percent of the Earth’s surface, the ocean is our planet’s largest habitat, containing 99 percent of the living space on the planet. This area holds the life of nearly 50 percent of all species on Earth. Like lakes, oceans are subdivided into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. The intertidal zone is the region along the shoreline between average low tide and average high tide. In other words, this region goes through cycles of submergence and exposure to air. Animals in this zone must be able to survive the extended periods

Before anything else, you should be able to find good trout fishing tackle that will suit your preference. Always remember that the goal is to decide the tactics that you will use to go trout fishing in the waters of Scotland, and that is the sole purpose of this article.

The female plays the biggest role in the relationship as she controls the food, and attracts the prey with her lure. This extreme case of sexual dysmorphism allows the female anglerfish to spawn whenever she needs to as she always has a mate available. The sperm travels through the mouth of a female and is fertilized to form a zygote. When the female is ready to produce her eggs, she lays them on a sheet made of jelly like substance two to three feet by 30 feet long. The sheet floats to the top of the ocean and when the eggs are ready they hatch and become larvae. Then the larvae eat plankton to sustain themselves, and eventually travel back to the bottom of the ocean as they grow older. The average female/male anglerfish has 46 chromosomes. Anglerfish are categorized by their genes, “They are characterized by the dorso-ventrally compressed morphology of the head and body, a wide and cavernous mouth, thin skin, an absence of scales and swimbladder, and a modified first dorsal fin ray (illicium) with a terminal esca, which serves as a lure.” (http://icesjms.oxfordjournals.org/content/65/7/1272.full) The variation in these genes can either be helpful or hurtful

The Kelp has a rich supply of iodine, calcium, sulfur, and silicon in their tissue. Kelp is also a dietary supplement for humans. Another plant species, The Open-Brain Coral, also contributes to the ocean floor. The Open- Brain Coral is found in major coral reefs of the world. This specific type of coral looks like a human brain that was split open. They feed after sunset, and eat many types of small creatures with tentacles. There are also various types of seaweed in many sorts of types of colors. The Red Algae is one of the old types of algae in the ocean. It contains over 7,000 species. There are various different types of animals that lie beneath the ocean floor. Then there are many different types of creatures. The Clownfish is a rare fish that reaches 4.3 inches in length. There are about 30 known species of Clownfish. All are born male, but have the ability to switch their sex, but only to become the dominant female of the group. The Giant Tube Worms reach up to 8 feet in length and 1.6 inches in diameter. They grow rapidly and quickly. They don’t have eyes, mouth, stomach, or legs, so they crawl to get around. They can survive in complete darkness, on dept of 5.280 feet. Tube Worms live in symbiosis, a mutually beneficial

Deep sea creatures have evolved in some pretty weird ways. Like the Anglerfish. When Anglerfish mate they morph together and are like that forever. Some deep sea marine fish have both male and female sex organs and many can change sex as well. Some of the creatures have evolved to live off of chemical energy instead of sun light.

Anglerfish - The Anglerfish belongs to the same family as number two on our list. Many consider it to be one of the ugliest animals on the planet, let alone the deep sea. Maybe its because its eyes look like those googly eyes that you used for art projects in kindergarten; Or It could also be because it has sharp, jagged teeth that look like they haven’t been brushed in a few years. It’s quite possible that this thing gave you nightmares after you first watched Finding Nemo as a kid. Talk about a jump scare!

A team of the university of St. Andrews have discovered that these fish spend most of their time in a Florida bay near the coast. The only way the conversationists might be able to prevent this sawfish to die out is by understanding their habitat more.

As you know seahorses are different from other fish. They may be different but that is a good thing because you might have some advantages from being different. Seahorses have a horse shaped and angled head. They have a long snout and a tiny mouth but that can be a good thing because then the seahorses can get into tiny spaces and get the food other fish can’t. Seahorses eat mysis shrimp which are shrimp that can reach anywhere between 4.4mm and 9.4mm and you can see right through them. If the shrimp is too big then the seahorse can make its mouth bigger like a snake and eat it. Seahorse also have a snake like tail which they use to swim and hang on to things like plants. Other fish have fins to help them swim but if seahorses don’t want to use their little fins they can use their tails. If the water is too rough all they have to do is hang on to a plant so they don’t get carried away. That coolest but weirdest thing about seahorses are their eyes. They can move both of their eyes in different directions at the same time. So they could see behind them and beside them at the same time. That is an advantage because they can see what is coming from both ways instead of just one way. So when a predator comes they can see them and hide or blend in. Being able to blend in is another advantage because most fish can’t do that. They can be one color and blend in with only one thing but seahorses can blend into anything. They are

These jellyfish can live in cold and moderate waters of the ocean between 4-28 degrees Celsius. They can usually live/be found by the coast in continental shelf regions like the Atlantic and Mediterranean (United Kingdom and Turkey). Adult compass fish can usually be found near the surface of the water, however, when the currents toward the surface are too strong for them; they tend to move to deeper waters, although it is scarce for them to be located below 30m but drift deeper if they feel threatened by a predator. They swim by using the movements of their bell which pushes water out and thrusts them forward.
