Cnidarians

The main difference between Hydra 10 and Hydra 20 is their capacity. Hydra 10 has a capacity for 10 gallons, while Hydra 20 has a capacity for 20 gallons. This means Hydra 20 can filter a larger volume of water compared to Hydra 10.

The two body forms of cnidarians are the polyp and the medusa. Polyps are typically sessile, tube-shaped organisms attached to a substrate, while medusae are free-swimming, umbrella-shaped organisms.

They mostly live in salt water, but a few species live in freshwater ponds and lakes.

Hydra is most visible in the Southern Hemisphere in the months of March, April, and May. It is a large constellation that stretches across a significant portion of the sky, so it may be easier to spot during those months when it is higher in the night sky.

No. Cnidarians don't even have a circulatory system.

The genes of the hydra are found on the chromosomes in the cell nucleus. Hydras have a simple genome with a few chromosomes that carry the genetic information necessary for their development and function.

No, an oyster is not a cnidarian. Cnidarians are a phylum of marine animals that include jellyfish and corals, while oysters are mollusks belonging to the phylum Mollusca.

No, hydras are multicellular organisms. They are simple animals classified as cnidarians, typically having cylindrical bodies with tentacles surrounding their mouths. They are capable of regenerating and reproducing asexually.

In Greek mythology, the Hydra was a multi-headed serpent-like monster that terrorized the swamps near the ancient city of Lerna. It was known for its ability to regrow two heads for every one that was cut off, making it a formidable opponent for heroes like Hercules.

they may move considerable distances by bending the column, attaching with the tentacles, releasing the basal disc, then flipping the column over and re-attaching. This behavior is termed somersaulting.

Hydra cells obtain oxygen through diffusion. Gases, including oxygen, are exchanged directly with the surrounding water through the body wall of the hydra. This process allows oxygen to enter the cells and carbon dioxide to exit.

A hydra is a small freshwater organism with a tubular body and multiple tentacles surrounding its mouth. It typically ranges in size from a few millimeters to a few centimeters long and is known for its regenerative abilities, with the capability to regenerate lost body parts.

According to Wikipedia, it is of the class "Hydrozoa": http://en.wikipedia.org/wiki/Hydra_(genus)

A hydra is a eukaryote. It is a multicellular organism that has membrane-bound organelles and a true nucleus containing its genetic material.

Cnidarians typically exhibit radial symmetry, meaning they are shaped like a wheel spoke with multiple identical parts radiating out from a central point. This symmetry allows them to respond to stimuli from all directions equally and efficiently capture prey in their aquatic environment.

Hydra reproduce asexually through a process called budding. A new individual grows as an outgrowth from the parent hydra and eventually detaches to become independent. In addition, Hydra can also reproduce sexually by producing eggs and sperm that fuse to create new offspring.

All cnidarians have on their tentacles stinging cells called nematocytes. They have no brains or a central nervous system. Another common feature is that they all can regenerate, letting them produce asexually (without the need for another partner) and to recover from injury.

Budding

Hydra have adapted to regrow if part of their body is separated. In an experiment, scientists ran a hydra through a sieve. When the cells were introduce to water, they eventually regrew into fully formed adult hydra.

No, cnidarians are not protists. Cnidarians are a diverse group of animals that include jellyfish, corals, and sea anemones. Protists are a separate group of eukaryotic organisms that are not classified as animals.

Hydras are aquatic predators that mainly feed on small invertebrates such as water fleas, insect larvae, and small crustaceans. They use their tentacles equipped with venomous cells called nematocysts to capture and immobilize their prey before consuming them whole. They are opportunistic feeders and will consume any small organism that comes within their reach.

In mythology, hydras are mythical creatures with multiple heads. In the natural world, hydras refer to tiny, freshwater creatures called hydrozoans. These tiny organisms are part of the animal phylum Cnidaria.

The hydras teeth were chucked into the ground which then reproduced skeletons (hydras children)
