  4. About the Portuguese man of war • Kingdom: Animalia • Family: Physaliidae • Species: Physalis • They eat small fish • The man of war has a body filled with 90% C02 {Carbon Dioxide} • It is an invertebrate • The venom from a man of war sting differs from the venom of the normal jellyfish. • The man of war is infamous for coming in swarms of 1000’s.

  5. Portuguese man of war label diagram Crest Blue, pink or pale purple gas filled body. Long, coiled stinging tentacles. Growth up to 165 feet [about 50 meters}

  6. What are it’s defencemethods and how do they work? • Its main defencemethod is obviously stinging with it’s tentacles. • It works when a predator of a jellyfish comes in contact with its tentacles and particles in the tentacles nematocysts inject allergic venom into the enemy’s body.

  7. Do Jellyfish have organs similar to a human’s? • Well a jelly fish doesn't really have a heart so its hard to say if it’s even a living creature. • They have a weird breathing system also they breath through gas diffusion that comes from the surface of its body. • Jellyfish also don’t have a brain but they have nerve which can detect odour, light and danger.

  8. What Methods do they use to hunt? • They use their long tentacles which grow up to 50 meters to hunt. • Their body stays above sea level and their tentacles stay below and when a fish comes by it gets paralysed • And the man o war quickly gets its prey and eats it.

  9. How dire can a sting from the man of war be to an infected human and why? • The venom usually deals severe pain to an infected human. The sting might also leave a allergic reaction, tragically if you are allergic to jelly fish you will die instantly. • The stings can also start fever, major shock to the infected human and heaps more devastating outcomes. • But you don’t have to worry statistics show that only several people die of man of war stings a year.

  10. Physical adaptations. • The first adaptation is that the man of war is wind driven meaning the wind helps it navigate and go to different destinations. • The second adaptation is that the man of war lacks the art of speed or surprise. So when hunting it stretches its tentacles to full length and does exactly what a fisherman would do it waits for fish to come in contact with its tentacles so the fish gets paralysed and the man of war quickly devours the fish. • The third adaptation is the man of war need long tentacles to catch fish at low levels of the sea. • The last adaptation is it uses the sea cucumbers liquid inside and rubs it against its own body for keeping warm.

  11. What method do they use to breed and why? • The man of war can’t really tell who’s male or female. So to breed the males rapidly shoot out sperm and the female takes the sperms into her and the sperms mix with the females egg fertilization.

  12. Food web • This is a marine food web including the man of war
