What is the difference between zebrafish and jellyfish DNA?

The fish DNA contains DNA of a jellyfish (Aequorea Victoria) and red coral (from Discosoma genus). Zebrafish with jellyfish DNA paragraph (GFP gene) are green colored, with the coral DNA (RFP gene) — they are red, and the fishes with DNA paragraphs of both the jellyfish and the coral are yellow colored.

What is the scientific name for jellyfish?

What is the difference between a jelly and a ctenophore?

# A cnidarian, a member of the phylum Cnidaria. ## A scyphozoan, a member of the class Scyphozoa (the true jellies). # A ctenophore, a member of the phylum Ctenophora (the comb jellies). Some writers prefer the term jelly, which does not imply that it is a type of fish.

What are ctenophores?

Ctenophora are commonly known as Comb Jellies, with over 150 species spread over 7 genera. They are found in oceans worldwide, although up to 75% live in tropical water. Ctenophores show many similarities to Jellyfish (Cnidaria), but they actually sit in an entirely separate phylum. Having said that, their taxonomic status is still debated.

Are ctenophores related to jellyfish?

Often, those prey are other ctenophores. For a long time ctenophores were regarded as distant cousins of jellyfish, with globby, transparent bodies, a circular mouth at one end and external and internal surfaces sandwiching gelatinous material.

How big do zebrafish get in captivity?

But in captivity, it rarely exceeds a length of 4 cm. » The male zebrafish is usually slender with a torpedo-shaped body. It can be distinguished from the female by the presence of golden stripes in between the blue stripes. The female zebrafish, on the other hand, has a larger belly and silver stripes between its blue stripes.

Why do zebrafish stripe patterns change color?

New research by Nüsslein-Volhard’s laboratory published in Science shows that the yellow cells undergo dramatic changes in cell shape to tint the stripe pattern of zebrafish.

How many species of jellyfish are there in the world?

Such a life cycle characterizes the order Semaeostomeae, which contains some 50 species of mainly coastal-water jellyfish, several of which have very wide geographic ranges.

What is the classification of a jellyfish?

Jellyfish, any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about 200 described species, or of the class Cubozoa (approximately 20 species). The term is also frequently applied to certain other cnidarians (such as members of the class Hydrozoa) that have a medusoid

The scientific name of the immortal jellyfish is Turritopsis dohrnii. Although it is in the Cnidaria family, it is not a true jellyfish, which is in the class Scyphozoa, not Hydrozoa.

How do ctenophores swim?

Ctenophores swim by operating their cilia like little oars on a galley, sometimes compared to The Wave people do at ball games. This is another important difference between jellyfish and comb jellies; jellyfish achieve locomotion by pulsating their bodies.

Do jellyfish eat ctenophores?

Some jellyfish and turtles eat large quantities of ctenophores, and jellyfish may temporarily wipe out ctenophore populations. Since ctenophores and jellyfish often have large seasonal variations in population, most fish that prey on them are generalists and may have a greater effect on populations than the specialist jelly-eaters.

Is a jellyfish related to a cephalopod?

In fact, jellyfish aren’t closely related to cephalopods at all (and neither are they closely related tocomb jellies, another gelatinous sea-going creature). Their closest cousins include corals and anemones. “Corals, anemones, things we call hydroids, sea pens, and jellyfish,” lists Dr. Ames.

The phylum Ctenophora have a diverse variety of body plans for a phylum of just a few species.

What do ctenophores eat?

When abundant in a region, ctenophores consume most of the young of fish, larval crabs, clams, and oysters, as well as copepods and other planktonic animals that would otherwise serve as food for such commercial fish as sardines and herring. In turn, however, comb jellies are themselves consumed by certain fish.

What is a ctenophore?

Ctenophores come in all shapes and sizes, but they share a common method of locomotion: eight rows of cilia, beating in mesmerizing synchrony. These bioluminescent blue-green “combs” light up coastal shores at night—as well as the depths of the twilight zone, where a number of species have yet to be formally described.
