H. maculosa has been known to bite humans when they disturb the usually reclusive octopus. Tetrodotoxin (TTX), the principle component of maculotoxin, inhibits the nervous system by binding to sodium channels on nerve cells to prevent the flow of sodium and release of neurotransmitters. Recent findings have shown that there are sodium channel variants that are either immune or resistant to tetrodotoxin. In most humans, however, victims of the blue-ringed octopus’s neurotoxin will enter into increasingly
still present in his stomach. Within a few hours, Dr. Marshall Westwood ‘s symptoms were subsiding and his condition improved. Dr. Marshall Westwood had been a victim of the puffer fish poisoning. This poisoning is due to a type of neurotoxin, tetrodotoxin that is pres...
Firstly I will start from explaining words predator and prey. Namely in ecology predators are those animals that survive by quarrying on other animals or plants for food. Many predators hunt and eventually kill their prey for example owls are predators and they prey on mice. Predatory animals may hunt in groups like wolves or may be a lone hunter like leopards. Preys are the organisms hunted by predators. Puffer fish is a great example of an animal which has an anti-predation protection mechanism
1. Watch the short film in the first room. Why did the grasshopper mouse not feel pain when stung by the scorpion? What kind of poison is tetrodotoxin? Ans: Grasshopper did not felt the pain when stung by the scorpion because the Grasshopper produces natural bio-chemicals to defend itself against the poison of scorpion by tricking the scorpion. Tetrodotoxin is a powerful poison found on liver and reproductive organ of some puffer fish. 2. What bird's feathers are poisonous, and what is the toxin
The blue ringed octopus Introduction: The Blue Ringed Octopus is a very fascinating animal because it is famous for its deadly poison, which is powerful enough to kill a person.

Three Weird Asian Foods for Your Cast-Iron Stomach Different cultures, different tastes and different dishes on the table – that's what best describe Asians' insatiable appetite. Insatiable in the sense that what's not edible to Westerners is edible to certain populace across Asia, whose inhabitants, either due to culinary creativity or survival instincts, eat things that may look disgusting or weird to the eyes but tasty in the mouth – as not to make the usual fares boring or not to let the stomach
Ebola. Zombie actually came from Haiti, but they are not what people usually show on TV and movies. In Haiti, there were witch doctors that would use these poor people as their slaves. A poison drugs the person, which is from a puffer fish called Tetrodotoxin, which paralyse the patient making it seems as if they have died. The person is then buried then witch doctor comes back at night and dugs out the supposedly dead victim. Once the Witch doctor has gotten the unfortunate victim, she then drugs them
Co-evolution occurs in nature as an evolutionary arms race with an ongoing cycle of response and selection between two species. In most situations when two species co-evolve, the two species will have a predator and prey relationship. In a predator and prey relationship there is a constant struggle for the predator to catch the prey and for the prey to deter or evade the predator. As a result, either the predator or prey will eventually acquire a trait via natural selection that will give them an
substance called tetrodotoxin (TTX). In an article in New Scientist (2001), Bryan Furlow gives an overview of TTX’s effects blended with a headlining news story: Dodo, a former voodoo priest, confirms that the recipe used to make the drug for zombiefication includes a powder derived from the puffer fish” (Efthimiou and Gandhi “Cinema Fiction vs. Physics Reality: Ghosts, Vampires, and Zombies”), basically they say that someone got poisoned with a powder foun in puffer fish known as Tetrodotoxin. This myth
Although it is impossible for humans to breathe underwater, what if it was a possibility? The human anatomy would need to change in order to support the same anatomy that allows fish to swim and breathe underwater. All fish have gills. Gills are tissues which consisting of filaments. These filaments have capillaries that allow the exchange of oxygen and carbon dioxide, acids, and ammonia. The gills are located on either side of the pharynx. “How Fish Breathe Underwater” states, A fish breathes by
It seems as though zombies are coming increasingly more popular in pop culture as time goes on. Countless movies, books, video games, and even TV shows based on zombies have dated back to 1932 when the first feature length zombie film, White Zombie, came out. But many people wonder where the images and ideas of the reanimation of dead people came from: rising from the grave; rotting, pasty, green skin; an uncanny taste for human flesh and brains that can all be ended with a blow to the head. As

As you probably already know zombies have been a pop culture staple for years…what I mean by that is, zombies have a huge influence over society…we really seem to
rings, appearing as a pattern on its dermal covering. When these rings flash, one can tell that the octopus has been threatened. Although this tropical marine creature may generally be calm, when it is agitated, it can bite with its beak and inject tetrodotoxin into the blood stream. This venom can quickly kill an adult human. Typically, the blue-ringed octopus, or Hapalochlaena Lunulata, resides among rocks and shells on the ocean floor and exhibits a camouflaged appearance (Mathger et al., 2012). However
In recent years, there have been a plethora of film releases that pertain to the central topic of zombies. Typically “zombies thrive in popular culture during times of recession, epidemic and general unhappiness” (Drezner). Zombie films began around the 1920’s, and continue to fill modern day theatres. These films, although dramatized for entertainment, are something that truly could, and have, occurred. These films have been modernized, in order to fit the desires and demands of a modern-day audience
The Blue Ringed Octopus is one of the most beautiful and intelligent creatures. It is Genus: Hapalochlaena and Species Hapalochlaena lunulata. In studying this animal, they have an amazing design, habitat, and diverse anatomy. Considering the Blue Ring Octopus, it is a very diverse and interesting animal. Although people have little knowledge of the Blue Ringed Octopus, it is one of the most interesting animals in the world. Of the many things that relate to its ecosystem, some main points would
of the voltage-gated sodium channels have been blocked off. In this case, the membrane can reach threshold if given a larger-than-normal stimulus. Sometimes neurons are negatively influenced by the voltage-gated sodium channels’ loss of ability. Tetrodotoxin (TTX) and saxitoxin are two of the deadliest poisons in the world, found in pufferfish and poison dart frogs, respectively. The reason they are so dangerous is that they block only voltage-gated sodium channels (as opposed to blocking both sodium
Concepts are how we give meaning to everyday things. We make, name, communicate, and imagine concepts all day everyday; concepts are vital to understanding this world we live in. A concept is an abstract idea or a cognitive unit of meaning. Zombies, for example, are a concept, but where did this concept of the living dead arise? Is there some religious link to this concept or is it an image of imagination? A zombie is defined as a fictional undead demon or a person in a rapt state being controlled
More and More people are becoming concerned about what they eat, especially if they consume food products that are manufactured in food industries. However, it is hard to know what exactly you are consuming if food industries provide false nutrition content and mislead consumers by placing false advertisements on the packaging. When a company produces a product that contains misleading label, consumers are not receiving complete information about the food they are eating which could lead to health
There are three different ways that frogs show parental care to protect their young. There are many species in which the adult frog guards over the eggs. The sex of the frog that guards the eggs all depends on the species. In some species the male watches over them and in other cases the female is the one who is doing the protecting. But in some cases it is not known whether it is the female or male because the external characteristics of both sexes are very similar. Some of these species lay their
Jellyfish Venom Almost anyone who has ever spent time near or in an ocean has been warned about being stung by jellyfish. Jellyfish have been ascribed a reputation as dangerous, often lethal animals. The exact actions of jellyfish toxins are not well understood, and the true danger presented by jellyfish is often exaggerated. This paper will attempt to answer several questions about jellyfish and venom. It will discuss what toxins make up jellyfish venom and the method in which these toxins
