Giant Pacific Octopuses Research Paper

Moon Jellyfish are ‘2 to ‘15 inches,so it’s hard to tell its weight. Moon Jellyfish are Invertebrates so they eat Mollusks,Crustaceans ,Tunicate Larvae, Copepods , Rotifers, and Nematodes.Even though moon jellyfish are beautiful and the most common,they also have enemies like the Sea Bird, Leatherback Turtle, Sunfish, and Humans.

The octopus it's things that people would expect them to eat. It will usually eat crustaceans off the ocean floor. These are creatures such as crabs, clams, snails, and lobster. There are even species that perform cannibalism

The cephalopodor octopus is a marine organism that inhabits many diverse regions of the ocean. Its food source consists of crabs, small fish, clams, mussels and other marine animals. The octopus is a predatory animal and has developed many skills to aid in its survival in the environment it has adapted to.

2) Octopus should be baited using the tentacles foremost so they cover the hook. As with the prawn the octopus should thread over the hook to disguise it.

Lobsters that are smaller than 1-1/2 inches hide in coral or see weeds. This provides shelter from predators such as flounder, cod, ocean pout, monkfish, sculpin, wolffish, and dogfish. When lobsters are adults they are much less vulnerable. The only predator for adult lobsters is man. Big lobsters inhabit offshore areas and only return home seasonally to shallow warmer waters. A female lobster can carry up to 50,000 eggs. A female lobster can only mate after it has molted. The developing embryos remain attached to the female for an estimated 9 to 11

How does it reproduce? It is viviparous, which means that females give birth to a large numbers of planktonic larvae in late winter. The juvenile of it is pelagic and the larvae remains planktonic

Type of habitat: It inhabits mainly around coastal areas and estuaries in the southwestern pacific.

Dactylozooids form these tentacles that hang into the waters below at an average depth of 10 meters and are used to ward off any predators, and capture any prey. Since dactylozooids can survive alone, they become a real danger as deadly, toxic cnidocytes can wash ashore and injury or even kill beachgoers. Physalis toxin is extremely potent because they must paralyze their prey instantly if they are to have a chance to digest it. The tentacles are also pigmented blue as a camouflage in the blue sea water. Young fish, eel, larvae or really any animal that passes through the tentacles is stung and, if small enough, brought closer to the body for digestion. Digestion is a fairly simple process in which the tentacles contract bringing whatever was captured closer to the gastrozooids that lie just below the upper pneumatophores. Enzymes released by gastrozooids break down the food and distribute energy throughout the body to all other

So far this year in science, we have accomplished interesting and challenging activities, such as the Octopus cup. This challenge is completed with six people pulling eight strings connected to one rubber band. The goal of the Octopus cup activity is to build a pyramid using six cups without touching the rubber band, and only the strings that it is connected to. The Octopus cup challenge has showed me the importance of communication, and that teamwork is key. Also, another challenge we have completed in class is the pink string activity. This activity involves you and a partner, you must place the strings around your wrist, then in the middle of both strings loop your partners string within your string. Afterwords you both must try to find

They look exactly like their parents, but on a much smaller scale. Because they are not very heavy, they swim around towards the surface of the sea sometimes being eaten by predators.

The creature blue-ringed octopus is known as the deadliest of its kind, yet is so tiny and small that a toddler can pick it up with just a thumb (Morse et al., 2017). However, be warned by the sudden change of colour as it is a warning due to the venom produced when they are about to attack. Medical importance to humans involves its poison (Williams et al., 2012). Octopus are marine animals famous for their rounded body, bulging eyes, eight long arms with tentacles and highly intelligent brain (Sullivan, 2017). The blue-ringed octopus of Australia is dangerous to humans when handled, stepped on or provoked (Underhill, 2010). For the purpose of this review, the taxonomy, morphology, reproduction, life cycle, habitat, feeding, behaviour, toxicity

Recently, we reported on a new study from scientists who managed to sequence the first octopus genome, trying to map out the cephalopod's entire DNA. Sure, what they found was extraordinary and they proved that octopuses are very different from other creatures, but you are not prepared for what is coming.

How do octopuses and squids reproduce? ”The male octopus uses a specialized arm called a hectocotylus to transfer sperm to the mantle cavity of a receptive female. The female lays strings of fertilized eggs on the roof of her den. She guards, cleans and aerates the eggs with water expelled from her siphon until hatching. This can be anywhere from 30 days to a year, depending on the species. The female may build a wall of rocks to seal off the den and will remain in the den until just before she dies, after the eggs have hatched. Squids often mate in large groups, and attach their egg capsules to the ocean floor or to seaweed. Most adult octopuses and squid die after reproducing. Their bodies are recycled in the food web, nourishing other animals, and ultimately providing food for their young when they hatch.” (Octopuses &

This article has everything on octopuses from hunting tactics to defense mechanisms. It also explains about “the death hug” and “the fatal

According to Octopus Cards Limited, the in circulation cards has more than 20 million that nearly three times the population of Hong Kong. The population of Hong Kong aged 16 to 65 has 95% people used the card. [2]
