Pink comb jellies have a sac- or egg-shaped body that is often tinted pinkish to reddish-brown. They occur as far north as the Baltimore area.
Pink comb jellies can be found in late summer to autumn in the middle and lower Chesapeake Bay, south of Kent Island, Maryland.Feed on planktonic organisms, including copepods and fish larvaeComb jellies are transparent, jelly-like invertebrates with bright, iridescent color bands. Sea walnuts often swim together in large swarms.Sea walnuts are the more widely distributed species. Most lobates are quite passive when moving through the water, using the cilia on their comb rows for propulsion,Adults of most species can regenerate tissues that are damaged or removed,Development of the fertilized eggs is direct; there is no distinctive larval form. If they run short of food, they first stop producing eggs and sperm, and then shrink in size. They occur as far north as the Baltimore area. Juveniles of all groups are generally At least in some species, juvenile ctenophores appear capable of producing small quantities of eggs and sperm while they are well below adult size, and adults produce eggs and sperm for as long as they have sufficient food.

Comb jellies grow to about 4 inches.Sea jellies are voracious feeders of planktonic organisms, including copepods and fish larvae. 6. Choose from a wide range of similar scenes.
The rows are oriented to run from near the mouth (the "oral pole") to the opposite end (the "aboral pole"), and are spaced more or less evenly around the body,It is uncertain how ctenophores control their buoyancy, but experiments have shown that some species rely on Ctenophore nerve cells and nervous system have different biochemistry as compared to other animals. The ciliary rosettes in the The outer surface bears usually eight comb rows, called swimming-plates, which are used for swimming. Comb Jellyfish . Get a 51.000 second ctenophores, predatory comb jellyfish invader stock footage at 25fps. They can consume almost 500 copepods per hour. Feeding. Detailed investigation of Ctenophores may balance marine ecosystems by preventing an over-abundance of copepods from eating all the On the other hand, in the late 1980s the Western Atlantic ctenophore The number of known living ctenophore species is uncertain since many of those named and formally described have turned out to be identical to species known under other scientific names.
(Photo by Will Parson/Chesapeake Bay Program)Comb jellies live near the surface of both shallow and deep waters and swim by beating their combs rhythmically to push themselves forward. Predators. The phylum is commonly derived from a common characteristic shared by the member species. They eat by continuously pumping water into their body cavities. Pink comb jellies have a sac- or egg-shaped body that is often tinted pinkish to reddish-brown. The sea nettle is smaller, found more in brackish water like the sound, and often has little or no color, appearing almost milky white.
Each comb jelly releases about 8,000 eggs per spawn. In bays where they occur in very high numbers, predation by ctenophores may control the populations of small zooplanktonic organisms such as Ctenophores used to be regarded as "dead ends" in marine food chains because it was thought their low ratio of organic matter to salt and water made them a poor diet for other animals. For instance, they lack the genes and enzymes required to manufacture neurotransmitters like serotonin, dopamine, nitric oxide, octopamine, noradrenaline, and others, otherwise seen in all other animals with a nervous system, with the genes coding for the receptors for each of these neurotransmitters missing.Cydippid ctenophores have bodies that are more or less rounded, sometimes nearly spherical and other times more cylindrical or egg-shaped; the common coastal "sea gooseberry", The tentacles of cydippid ctenophores are typically fringed with tentilla ("little tentacles"), although a few genera have simple tentacles without these sidebranches. They are present year-round but are most common in spring and summer.
However some deeper-living species are strongly pigmented, for example the species known as "Tortugas red"The comb rows of most planktonic ctenophores produce a rainbow effect, which is not caused by In ctenophores, bioluminescence is caused by the activation of calcium-activated proteins named Ctenophores are found in most marine environments: from polar waters to the tropics; near coasts and in mid-ocean; from the surface waters to the ocean depths.Ctenophores may be abundant during the summer months in some coastal locations, but in other places, they are uncommon and difficult to find.

Another type, comb jellies, are not true jellyfish and do not sting. When the food supply improves, they grow back to normal size and then resume reproduction.
