Introduction

The Box Jellyfish is one of the deadliest ocean creatures in the sea.

Some Q&A about Box Jelly fish Anatomy

Why it responds to stimuli

Throughout its epidermis is a dispersed organ system called the “Nerve Net”. The Nerve Net is a Type of Nervous System found in the Phylum Cnidaria. But it is a very basic in what it can interpret, pain, chemicals, and touch. One draw back of this system not having a brain is that if touched it will respond in the same way regardless of what is touching it, and where [1]. The responses are processed thorough the Rhopalia, which are hidden in the dips of the bell, the box shaped thing that has the tentacles dangling down form it. Now the Rhopalia are a combination of ocelli and statolith [2]. Ocelli which basically means simple eye [3], and Statolith, which detect gravity. So there fore these Rhopalia can sense light, but not where it’s coming form and comprehend gravity.

Why does the jellyfish need to be able sense gravity? Because it needs to tell how deep it is and it might use it to keep from capsizing.

The box Jellyfish has 24 ocelli dispersed in clumps around the four sides of its cube like body. [4]

How does the Box Jelly Fish Move?

Jellyfish normally drift along with the current from place to place. But jellyfish can also move their tentacles to capture prey, but it has been theorized that box jellyfish pursue prey moving around about three knots per hour. [5] The Rhopalia control the swimming by rhythmically opens and closes the bell.

Why does it Have Tentacles, and what does it Use them for?

The box Jellyfish has tentacles to trap prey . This happens when some thing touches one of the jellyfish’s tentacles, nematocysts stun or kill on contact. The only thing not affected by the nematocysts are the sea turtles who eat the box jellyfish.

What other kinds of organs do jellyfish have?

Since this page is specifically talking about box jellyfish you can learn more Jelly Fish by: wikipidea. Be assured that box jellyfish have all the same organs as normal jellyfish do.

on a special note the venom is a neurotoxin.

What can I do to protect my self from it’s sting?

you can do as they do in Australia, and wear a full body panty hose or spandex, because erecting a net along the perimeter of where you are going swimming is too much work. and some species can slip through the net. [6]

Reproduction

The Reproduction is an important part of life no matter what kind of organism, because with out it species would cease to exist, it is one trait that natural selection can not weed out if it wants to continue its species.

The reproductive cycle

Jellyfish is either male or female, when its ready to mate the male jellyfish releases sperm into the females mouth, then the sperm enters the ova, then the “right” folws

The egg of the Jellyfish floats freely in the water
The egg metamorphoses into a larva called a plana
The larva swims to an opportune location
It attaches it self to the ocean floor becoming a polyp
The top opens up to catch nutrients littlie bits of food, and the beginning buds of tentacles form
The tentacles continue to grow in length as the dossal larva grows
It continues to grow bigger
It enters the segmented polyp stage
Ephyra “immature jellies” begin to form
They break off
The ephyra starts to mature
The ephyra reaches the adolescence stage
The adult jellyfish is ready to reproduce

Ecology

Obviously jellyfish being a floating marine animal lives in water. It can only be found in the ocean.

What type of water does it flourish in?

Jellyfish normally flourish in water with lots of food for them to eat. Also where there has been agricultural run off where the land has been enhanced with phosphorus and nitrogen. The chemicals make certain types of plankton grow more proficiently so there is a plethora of food for the fish jellyfish eat. So there are a bunch of small fish that Jellyfish eat these plankton, more of the fish survive, more of them reproduce so there are a ton of fish that jellyfish eat now, but this process takes a few years. Jellyfish are also replacing, the declining fish population. [7] [8]
