A lionfish is a carnivore and they feed on small crustaceans and fish including the young commercial species such as snapper and grouper. They affect native fish populations and commercial fishing has yet to be determined. Lionfish catches its prey by hiding in a crevice in the rock or coral and then ambushing it was as it swims along. Scientists dive to study lionfish sometimes the kill them and then they would trace their DNA. A female lionfish releases between 2,000 and 15,000 eggs in the water , which means the male fish is fertilized. Lionfish is a prey of a couple of predators depend on size to the large size of the lionfish an the fact of there apperance.
Name – Arius felis Name – Hardhead catfish 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.
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...
There’s No Real Good Guy In the movie, “Blackfish” we are exposed to the fact that the way orcas are treated at SeaWorld is worse than we are lead to believe. We see how they are forced to swim in tiny pools and how they can only be fed if they preform well. After seeing this it makes you feel like the only way to help these poor creatures is to jump on the animal activist wagon and to free all the whales like in “Free Willy”. But is that really the right way to go?
Understanding other people’s perspective is vital when it comes to making someone a more informed and a more sympathetic person. For example, in politics, there are two main sides; the democrats and the republicans. These two sides almost never see eye to eye, but when they see from the other’s point of view, an agreement can be made.
But occasionally the younger sharks are preyed on by bigger sharks that do not necessarily have to be Bull sharks they can be become prey to any larger species of shark and occasionally a crocodile. However there are parasites like Pandarus sinuatus, and Periscopus dentatus that use the surface of the shark’s skin and use it to survive (Curtis). Though that does not in anyway decrease or increase the economic uses for the bull shark, its effects on the environment, or level of danger to humans. In certain places around the world the amount of bull sharks is decreasing slightly, because sharks can be harvested to make fish food, for their meat, for oils, and their fins for shark fin soup, or in asia their skin can be used to make “good leather” (“Bullshark”; Curtis). Even though their numbers are thought to be decreasing according to the International Shark Attack Files, otherwise known as the ISAF, has reported that there have been at least 70 reported unprovoked attacks on humans of which 17 were fatal, but that is only the known number of the reported attacks by bull sharks there most likely have been many more attacks that went unreported (“Bullshark”; Curtis). They are known for being one of “the most dangerous sharks in the world” because they along side the tiger shark,and great white they are the most common sharks to attack a human
Lionfish have brown and white stripes covering their body (NOAA, 2011). Lionfish have broad pectoral fins, and long individual dorsal spines that contain the venom glands in the tips (NOAA, 2011). The venom of the lionfish is only intended as a defense mechanism and not meant to kill. The spines of the lionfish deliver a sting that can result in severe pain, respiratory distress, and even paralysis (NOAA, 2011). Lionfish are found in almost all tropical marine habitats consisting of warm waters due to their invasive behavior. Their native range covers a very large area from western Australia and Malaysia east to French Polynesia and off the east coast of Australia to the Kermadec Islands of New Zealand (NOAA, 2011). Lionfish have been found along the coast from Florida to North Carolina. The first lionfish was reported in South Florida waters in 1985 with additional sightings occurring until they were documented as established in the early 2000s (NOAA, 2011). Lionfish are very popular aquarium fish, especially in the U.S making them important to the aquarium trade. There are two possible ideas about how the lionfish were introduced into the Atlantic. The first is through ballast water, the water carried in the bellies of the enormous transport ships of intercontinental trade (Whitney, 2003). Larval lionfish have low oxygen and food needs which makes surviving movement in ballast water a possibility (Whitney, 2003). The second possibility is that a number of...

There is a squid-like monster seen off the coasts of Norway that is a mile and a half in circumference named a Kraken. Legend says these creatures have the ability to squirt their blinding venom into the victim’s eye to cripple them. (...
Along with having camouflage, all species of octopi are known to be venomous. Only one species is known to be dangerous to humans. (The blue ringed octopus which is only 5-8 inches long) Octopi will only use their venom to defend themselves against a predator when they feel threatened or to paralyze its intended meal. The venom then dissolves the meat so the octopus can easily consume it.
We started to touch them and the starfish had such a unique texture. Afterwards, we washed our hands and headed outside and joined a line that was heading into a big, blue tent. We went inside and we were both surprised and excited to see tons of different-looking and sized stingrays swimming graciously throughout the pool. Everybody leaned over and reached their hand in the water, hoping that their hand would touch a back of a stingray. At first, I was scared to put my hand in the water because I didn’t want to accidentally touch the tail of the stingray even though they removed the barbs so they couldn’t sting you. Kristen didn’t have any trouble touching them, but for me on the other hand, it took a little longer. Kristen really wanted me to touch one so she grabbed my hand and slowly put it into the water. Having my sister there with me made me feel a lot less scared. We saw a small stingray heading our way, so Kristen lowered my hand and then my hand touched the back of the stingray. I was surprised of how smooth it was. It was as smooth as a fleece blanket. I was really happy at the end that Kristen encouraged me to touch one. After that I was able to touch a few more, except there was a big black covered sting ray with white spots that was probably five times bigger than the rest of them, that I was scared to touch and so was Kristen. We exited the tent and got our picture taken with the view of the city and Lake Michigan.
A poem without any complications can force an author to say more with much less. Although that may sound quite cliché, it rings true when one examines “The Fish” by Elizabeth Bishop. Elizabeth’s Bishop’s poem is on an exceedingly straightforward topic about the act of catching a fish. However, her ability to utilize thematic elements such as figurative language, imagery and tone allows for “The Fish” to be about something greater. These three elements weave themselves together to create a work of art that goes beyond its simple subject.
The purpose of the second MCAS essay was to further prepare the sophomores for the tenth grade ELA MCAS long composition. We needed to learn how to write MCAS essays well to score good grades.

It also had to follow the guidelines of the prompt which was to write about a character in a work of literature who has developed a friendship with someone who is disapproved of by others and explain how the relationship relates to the work as a whole.
Other suggestions have been made to teach and encourage native predators to eat lionfish, such as groupers, sharks, and eels (Hackerott et al., 2013). In fact, lionfish have been found in the stomach contents of some Atlantic and Caribbean fish, though
A black oriental goldfish swims pass me. His black eyes are huge! It's as if someone inflated his eyes. He seem to be a very calm and sad fish- I see another goldfish swim by me. This one is the fattest and most friendly one When the owner would stick the tip of his finger in the water, the fat one would quickly swim to the top and nibble on the finger. Then he'd quickly swim away because what he thought was food was actually the finger.
One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in any warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans. The whale shark is a species with a fascinating ecology, life history, behavior, anatomy
