How do jellyfish feed and digest?
Most jellyfishes are passive drifters that feed on living or dead preys: small fish, eggs, zooplankton and other invertebrates that become caught in their tentacles. Preys are brought (by tentacles, if they have any) into the cavity, called coelenteron, where it is digested.
Jellyfishes have cells called cnidocytes, which contain nematocysts, and located usually on their tentacles, mainly. Whenever a prey comes in contact with cnidocytes, hundreds to thousands of nematocysts' filaments are ejected into the prey's direction. These stinging cells are thus able to latch onto the prey, and the tentacles, or the oral arms (manubrium) bring the prey item into their mouth for digestion.
Is a moon jellyfish ectothermic or endothermic?
no. endothermic means it is warm blooded. only mammals and birds are warm blooded. jellyfish are cold blooded
Answer:
Endothermic is one of the three methods animals have of maintaining their body temperature. All of these used to be lumped together as being "warmblooded" and was thought to be the trait of mammals and birds alone. Recent studies indicate that many existing creatures other than mammals can exhibit part of the warm blooded trait (tuna, swordfish) and some extinct non-mammals (dinosaurs) were also warm blooded. The three temperature regulating methods are: # Endothermy: control tof body temperatures through internal means (muscle shivering, fat/sugar burning) # Homeothermy: maintaining a stable internal body temperature regardless of external itemperatures. # Tachymetabolism:maintaining a high resting metabolism
Jellyfish exhibit none of the ways of being "warm blooded" including being Endothermic.
Which ocean zone does a moon jellyfish live in?

They have a high powered sting that sends a jolt of energy into our nervous system and causes a lot of damage to our sensitive body don't get your nervous and respirator , digestive and circulatory mixed up because they all have a different job then just all being the same
What animal category are jellyfish in?
Fish, amphibians, birds, reptiles, and mammals are all vetebrates. Jellyfish are not vertebrates and do not belong to any of the above categories. Instead, jellyfish are invertebrates belonging to the phylum Cnidaria.
Jelly fish have a single opening digestive track. That mean whatever goes in has to come out the same way.
Can a jellyfish still sting you if it is dead?
IF something happens to the bee and it doesn't use its stinger and it dies, it still has its stinger. The stinger is still able to be used even after death. So if you step on a dead bee it can still sting you.
