Can you keep comb jellies?
This species of Comb jellyfish is found all year in a very wide range of temperature. ... They can be kept at 50-80° F. If possible, we recommend keeping them cooler, around 60° F.
Are comb jellies rare?
Despite their importance for understanding animal evolution, most information about ctenophores comes from living species alone as fossil comb jellies are extremely rare due to their gelatinous bodies. ... These 500 million-years-old fossils were found in the Marjum Formation in the House Range of Utah.
What does comb jelly eat?
Feeding. Sea jellies are voracious feeders of planktonic organisms, including copepods and fish larvae. They can consume almost 500 copepods per hour. They eat by continuously pumping water into their body cavities.
What do blood belly comb jellies eat?

Many of the deep-sea animals the bloody-belly comb jelly preys upon can bioluminesce, or create their own light.
Why are they called comb jellies?
Comb jellies are named for their unique feature: plates of giant fused cilia, known as combs, which run in eight rows up and down their bodies. ... Many microscopic organisms, such as bacteria, also use cilia to swim—but comb jellies are the largest known animals to do so. The comb-rows often produce a rainbow effect.
How old are comb jellies?
According to the Smithsonian National Museum of Natural History, the comb jelly is at least 500 million years old!
What are comb jellies classified as?
ctenophore, byname Comb Jelly, any of the numerous marine invertebrates constituting the phylum Ctenophora. The phylum derives its name (from the Greek ctene, or “comb,” and phora, or “bearer”) from the series of vertical ciliary combs over the surface of the animal.
Where do comb jellies live?
Habitat and Range
Ctenophores live all over the world, from the tropics to the poles and from the ocean surface down to its depths. Comb jellies are not found in fresh water. They live in the ocean and in brackish bays, marshes, and estuaries.
How is a jellyfish immortal?
Jellyfish, also known as medusae, then bud off these polyps and continue their life in a free-swimming form, eventually becoming sexually mature. ... Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal, although in practice individuals can still die.
How do jellyfish mate?
Some of these species are considered jellyfish, despite never taking the "medusa" form (free-swimming gelatinous body with tentacles) often associated with jellies. Females then take up the sperm.
