Swordfish: Questions And Answers

The terrestrial runoff spawned at around the time of major storms that wash large amounts of nutrients promotes plankton to blooms, which increase the food for many animals including Crown-of-Thorns Starfish larvae. The Great Barrier Reef receives runoff from 35 major catchments, which drain 424,000 square kilometres of coastal Queensland (Reefplan.qld.gov.au, 2012). Attacking the Crown of Thorns Starfish problem is through an integrated pest management approach that may be achieved by improving water quality as the long-term benefits to the health of the Great Barrier Reef.

Description – Hardhead catfish have six rounded barbels that stick out from their chins like whiskers. These barbels help the catfish find crabs, fish and shrimp in the muddy bays where they live. The dorsal and pectoral fins each are supported by a sharp, slime-covered barbed spine. The catfish is covered in a mildly toxic slime, that causes severe pain, and swelling, should the catfish cut you. The dorsal spine normally is held erect when the fish is excited and a tennis shoe or even a leather-soled shoe offers little protection. Adults may reach two pounds or more, but the average is about 10 inches and half a pound.

Devilfish. This purple, seven-armed octopoid monstrosity is the size of a horse, with hook-lined tentacles and cold, blue eyes. Devilfish CR 4. XP 1,200.

Blacktip Reef sharks are unique organisms that appear as the way their name describes it. The sharks have black tips on its caudal and dorsal fins, as well as angled saw-like teeth and a round and small snout. Other fins that this fish has is its two pectoral fins, pelvic fin, and an anal fin. These sharks can grow to be six to seven-feet long and have white bellies and dark backs, this allows the shark to disguise itself with the obscured seafloor and the lighter ocean surface.

They have different predators, and sharks can be one of them. Their body is segmented and has the presence of a cephalothorax. The killer shrimp has an open circulatory system, what means that they don’t have veins, but they still got a heart that helps on the circulation. They can generate forces that are more than 1000

Most people would not appreciate a stranger walking into their home unannounced, taking their food, and making themselves at home. That is exactly what lionfish are doing along the Florida coastline. Lionfish are an invasive species that need to be contained. The reefs that they consistently invade off of the coast of the Florida are not the lionfish's natural habitat. This invasive species takes shelter and resources out of the reef that other species need to survive, and they destroy the environment around them. Humans have complicated the balance of the ecosystem by introducing lionfish, and now they need to help rectify the situation.

Black sea bass are fairly stout-bodied fish, with a long dorsal fin, and large pectoral and pelvic fins. The rounded tail sometimes has a long streamer trailing out from the top edge. Each gill cover has a flat spine near the outer edge. Mature males have a fleshy dorsal hump just anterior to the dorsal fin. The background color of the black sea bass (smokey gray, brown, or bluish black) is marked with darker patches and light speckles. The belly is only slightly lighter than the sides. Young sea bass are green or brown with a dark lateral stripe running from the head to the tail. Juvenile and adult black sea bass feed upon a variety of benthic invertebrates such as rock crabs, hermit crabs, squids, and razor clams. Black sea bass adults typically

a Regal Angelfish is known or identified by it's color crazed color's.Although it's orange it has blue,white,yellow,and black vertical (up and down) so that's how their also known.they are also known by the stripes on their side.It's also known by it's tail and side fin's because there yellow.So that's how the Regal Angelfish are known.

Black Fish uses the death of a recognized Killer Whale trainer at SeaWorld, Dawn Brancheau who was one of Tilikums trainers thorough his twenty years in captivity, almost as a framing device to explore the theory that possessing Orcas in captivity is corrupt and unnatural for the whales. In Black fish, there are many different tragedies that went on while the Orcas were in captivity. Fisher men separated the young from the mothers and took them into SeaWorld. Many of the workers were unaware of all of the immoral actions they were taking part in. Tilikum was the Killer Whale that ended up killing Dawn Brancheau and causing a stir in SeaWorld. Having Orcas in captivity damages them but, the trainers were scared to leave because they want to continue to care for the whales. There is a relationship shared with the trainers and the whales yet it is obvious that very little was taught in the SeaWorld industry about these intelligent mammals.

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).

As John Webster, Professor of Animal Husbandry of the University of Bristol argues, "to say that a fish cannot feel pain because it doesn't have a neocortex is like saying it cannot breathe because it doesn't have lungs." But simply, fish possess pain receptors, their brains produce natural painkillers called endogenous opioids and they avoid noxious and threatening stimuli. Such behaviors

In 1985 a fearsome predator was introduced to the northwest area of the Atlantic Ocean. This predator has spread rapidly for decades, destroying the habitats in which it invades. No one has been successful in keeping this predator under control. This invasion has been like no other for a marine species.

Ideas that are powerful effectively influence and evoke cognition of the audience, hence composers aim to present powerful ideas in their documentary. Blackfish is a documentary which concerns the captivity of Tilikum, an orca held by SeaWorld involved in the deaths of three individuals, and the consequences of keeping orcas in captivity. In the documentary "Blackfish" composed by Gabriela Cowperthwaite, the idea of animal cruelty is explored. Through various documentary and cinematic techniques and emotional appeals, Blackfish exemplifies their argument and engages its audience in the discussion of the Marine Park industry and the effect of animal conservation.

They can swim at thirty five miles per hour(Institution, Smithsonian). They also have seven rows of teeth(Institution, Smithsonian). They have a total of three hundred triangular serrated teeth(Bradford). When Great white sharks are in the womb they supposedly swallow their own teeth. The first time they sink their teeth in their prey, it is called a sample bite. Sharks normally go up to their prey and taste them to make sure the want to eat them(Bradford). That's why most attacks are not fatal, because the shark tastes the human and thinks yuck that is not what I want to eat and spits them back out. They don't normally mistake humans for food considering only five to ten happen every year(Bradford). Once they sense food they need to get to it fast. They can swim up to fifteen miles per hour(1). Great Whites have to be fast at Cape Cod because they can not sneak attack the

A shark has multiple rows of teeth. The mouth of sharks is in the front of the head. In some species, sharks teeth are replaced as much as once a week. Some sharks have teeth used to crush and grind. These are some what like what humans have. They also have sharp teeth. These can be compared to incisors that humans have. These types of teeth are very important to sharks because they are carnivores and depend on their teeth in order to eat their prey. A sharks body in covered by scales which cover their bodies. These scales make the skin of a shark very rough and strong.
