But despite their name, jellyfish aren't actually fish—they're invertebrates, or animals with no backbones. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth. ... Jellyfish digest their food very quickly.
Is jellyfish a mollusk?
Ans: Phylum mollusca include soft bodied animals with hard shell Eg: snails, octopus, mussels, oysters. Phylum Coelenterata contain special structure called coelenteron where the food digested.It include jelly fish and sea anemones.
Are jellyfish prokaryotic or eukaryotic?
The evolution of jellyfish began as a small, crude, organism called a prokaryote. Through millions of years of evolution, prokaryotes eventually became eukaryotes, which possess membrane bound organelles. Eukaryotes developed into multicellular organisms of the kingdom Animalia.
What is the most common type of jellyfish?
The Aurelia Aurita, known as the moon jelly, is the most common and widely recognized jellyfish species. Though it has venom, it is harmless to humans—it's even a popular dish in China!
What is the largest known species of jellyfish?

They can have up to 1,200 tentacles, which originate from under the bell in 8 distinct clusters of 70 and 150 tentacles each. These tentacles contain large amounts of neurotoxins.
Does a jellyfish poop?

They have an internal cavity, in which digestion is carried out. This cavity has a single aperture which functions both the mouth and the anus.

Cephalopods have three layers of tissue while jellyfish only have two, and two openings to their digestive tracts while jellyfish only have one.
Are jellyfish a single organism?
Jellyfish are single organisms that are free swimming and capable of moving themselves through water. ... The single celled organisms that make up these colonies are so dependent on one another that most can't survive alone.
Are jellyfish heterotrophic or autotrophic?
Jellyfish are omnivores. Jellyfish get their energy from phytoplankton. They are a heterotroph.
Is jellyfish multicellular or unicellular?
Jellyfish and sea anemones are both part of the phylum Cnidaria. They are multicellular, diploblastic, radial symmetric organisms with nematocysts.
Are jellyfish asexual?
Throughout their lifecycle, jellyfish take on two different body forms: medusa and polyps. Polyps can reproduce asexually by budding, while medusae spawn eggs and sperm to reproduce sexually. Learn more about the lifecycle and reproduction of jellyfish.
