Box Jelly fish is a special type of jelly fish. It is also known as Cubozoa. The scientific for this particular organism is Chironex fleckeri. These jelly fish look really beautiful and elegant but they are very lethal.They are extremely dangerous organisms. They have the ability to instantly stun or kill their prey.Their tentacles have certain toxins that manipulate the organisms nervous system and shut it down that does not allow the organism to breathe properly and as a result of which the organism chokes and dies. When the jelly fish inserts the toxin into the organism from its tentacles it can also paralyze the organism which makes it impossible for the organism to find a way to escape. The toxin released into the organism does not allow the muscles to contract or relax and without the relaxation and contraction of muscles the trapped organism cannot move(paralyzed).
These Box jelly fishes are also sea wasps and marine stingers. They are mostly found in the coastal waters of Northern Australia and throughout the Indo Pacific. They are pale blue and transparent in color. They get their name from their cube like shape of their bell. These jelly fishes can have up to fifteen tentacles that grow from each corner of the bell and each tentacle can reach about ten feet(3 metres) in length. Each tentacle has about five thousand stinging cells. These stinging cells are activated not by touch but by the presence of a chemical on the outer layer of its prey.
The venom of the box jelly fish is regarded as one of the most deadly in the world. The venom contains various toxins that attack the nervous system, skin cells and and heart. The venom is overwhelmingly powerful and strong that the organism can even...

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 use of model organisms in pre clinical trial is relied upon for the collection of safety and efficacy data prior to first in human clinical studies. The crustacean Daphnia magna is one model organism, whose heart rate is reported to react similarly to the human heart rate, when exposed to identical compounds (3).
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...
Cone snails are some of the most toxic animals in the world. Cone snails have a small range in the reefs of the Indo-Pacific area. Anyone who gets stung by one of these snails likely has only a few minutes to live. However, cone snail venoms are made up of conotoxins, biologically active peptides that target neurons and muscles. Snail venom used to paralyze the prey so because of their compounds with medicinal properties cone snail can help to dismiss the cancer and produce approximately hundreds of more powerful morphine.

The outer tentacles probe for a potential meal, then the inner sensors decide if the prey is edible. They are covered in thick, blackish-brown, water-repellent fur, and have large scaled feet and a long, thick tail. This animal is by far one of the most interesting animals in the world, despite looking like a cross between a rat and an octopus. The way it behaves and utilizes its star nose is fascinating and makes it very unique when compared to other animals.
Since this first encounter I have caught lots of these magnificent fish and as the years go by they seem to keep getting bigger and bigger. I have developed several baits and presentations that help me to catch these fish and I would like to share them with you.
3. Watch the video on Jellyfish sting, and briefly explain how it can be treated
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.
The major thing about Mr. Wallace’s article is his concern about suffering of Lobster which he briefly explain the facts, he’s article feature the Maine Lobster Festival in Maine which the festival will cook 25,000 pound of lobsters, the World Largest Lobster Cooker as they call it, lobster will be cook in a gruesome way which he is concerned. Mr. Wallace characterized the lobster that boiling them is really hard for him to watch. Example is in his article he said that “Lobster looks like they are suffering as they hang their claws in the pot”. But this explains why the violent reaction of lobsters to boiling water is a reflex to noxious stimuli. And to add, Based on review by the Scottish animal welfare group Advocate for Animals released reported, a scientific evidence that strongly suggests that there is a potential for lobsters to experience pain and suffering. This is primarily because lobsters and other decapod crustaceans have opioid receptors and respond to opioids analgesics such as morphine in a similar way to vertebrates, indicating that lobsters' reaction to injury changes when painkillers are applied. The similariti...
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.
