Angler Fish Research Paper

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

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.

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.

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.

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

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

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.

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.

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.

“The Fall of the House of Usher”, a short story by Edgar Allen Poe, follows an unnamed narrator as he rushes to the aid of Roderick Usher per his request. When the narrator arrives at the Usher’s house, he finds it in a dilapidated state with a crack running from the base of the house to the roof. The narrator finds his friend, a man whom he has known since he was young, pale and lacking the appearance of a human being. The narrator quickly comes to see some connection between his friend’s ailment and the state of his sister, Madeline. Shortly after the arrival of the narrator, Roderick’s sister dies of the illness that has plagued her for so long. However, with her death, Roderick begins to change and fear starts to close its cold hands

Our advice will focus on solutions that address the goals and issues that are important to you.

The best place to find the best deep sea fish is near a reef. Many coastal cultures get up to 25% of their food from reefs. Reefs are natural nurseries for many ocean species, and wherever the tiny ones live, the big ones search. Another plus is the great diversity of species you'll find near a reef.

After fifty-two days of working, Nehemiah and his people had completed the wall. Nehemiah set up the doors of the wall and he was ready to arrange all the people who came up out of captivity from the land of King Nebuchadnezzar. When the people of Israel were all together in their towns, they asked to the scribe Ezra to read the Book of the Law of Moses. Public reading was a common practice in the ancient Near East, because of the lack of accessibility to written material.
