What kind of diet does the jellyfish have?
Jellyfish feed preferentially on zooplankton, organisms between 1 millimeter and several centimeters that live floating in the body of water.
What kind of organism is the jellyfish?
Jellyfish belong to the zoological group of Cnidarians, the vast majority of which are marine animals that are divided into four classes: Hydrozoans, in the case of hydras, small jellyfish, and other colonial polyps. Cubozoans, which include the box jellyfish.
What kind of excretion does the jellyfish have?
Each and every one of the animals produces waste, in our own case the jellyfish do not excrete compact but rather they generate products that dissolve inside the water.
What animals have mixed digestion?
Mixed digestion.
In certain lower metazoans, such as coelenterates, digestion is partly intracellular and partly extracellular. These animals have cells that secrete enzymes lining the gastric cavity. Food reaches the cavity and begins to be digested (extracellular digestion).
How is the diet of Cnidarians?
FOOD: They are essentially carnivorous; Since their own bodies are very extensible, they can expand and swallow bulky prey. They have extracellular digestion in the gastrovascular and intracellular cavity. The undigested edible is expelled through the mouth.
What is the digestive system of jellyfish?
They have an internal cavity, where digestion takes place, called the gastrovascular cavity and which has a single opening that performs the functions of mouth and anus. Jellyfish are carnivorous and can rapidly increase in size and form large numbers of individuals as the food proliferates.
What is the unicellular or multicellular jellyfish?
They are pelagic animals, that is, they live in the water column, not at the bottom. It is a very old group of organisms, which have existed for at least 500 million years (perhaps a quarter of it takes place more than 700 million years), being the oldest group of multicellular organisms on the planet.
What kind of cell is the jellyfish?
about jellyfish
This animal group has stinging cells that they use to capture prey and also as a defense. These same cells have a capsule inside which there is a coiled filament and a poison.
What kind of digestion is the jellyfish?
They have an extracellular digestion in the gastrovascular and intracellular cavity. The undigested edible is expelled through the mouth.
What type of asexual reproduction does the jellyfish have?
Asexual reproduction is normally in the form of budding. Jellyfish also form by cracking buds (gonophores) on polyps, either from the walls of common hydrants or in specialized gonozoids.
What is the genus of breathing jellyfish called?
Jellyfish do not have a respiratory system, so oxygen diffusion occurs at the tissue level.
Where is mixed digestion monitored?
It consists of digesting the nutrients inside the cell, using the digestible enzymes of the lysosomes. This is the only system available to little evolved animals to digest their food. Mixed digestion. It begins in the gastrovascular cavity, secreting proteolytic enzymes.
What animals perform internal digestion?
Protists and sponges carry out intracellular digestion, in which they swallow microscopic food particles.
What kind of digestive system do insects have?
The digestive system of insects consists of a single anterior part formed by the mouth with salivary glands, esophagus, storage region and in certain gizzards, a middle region, formed by the stomach and gastric caeca, and a posterior one, where the digestive organs appear. intestines, rectum and anus.
What are the animals that have a simple digestive system?
Reply. Invertebrates, for example: earthworms, flat worms, crustaceans, mollusks, and all insects and arachnids contain an easy digestible system.
