What are the examples of ctenophara?
Some examples of ctenophores include the Venus's girdle (Cestum veneris), sea walnut (Mnemiopsis leidyi), and comb jellies such as Beroe and Pleurobrachia. Ctenophores are gelatinous marine animals commonly known as comb jellies, distinguished by their transparent bodies and rows of cilia for movement.
What are some examples of ctenophora?
Some examples of ctenophora, also known as comb jellies, include the Venus girdle, sea gooseberry, and lobate ctenophores. These gelatinous marine organisms are known for their bioluminescence and unique comb rows used for movement.
What are coelentrates?
Cnidarians, also known as coelenterates, are a phylum of animals that includes jellyfish, corals, and sea anemones. They are characterized by possessing specialized stinging cells called cnidocytes used for capturing prey and defense. Cnidarians have radial symmetry and a simple body plan with a central mouth surrounded by tentacles.
What is metagenesis in coelentrates?
Metagenesis, also known as alternation of generations, is a reproductive phenomenon in cnidarians where individuals alternate between a polyp and medusa form throughout their life cycle. The polyp form is a sessile, cylindrical structure that reproduces asexually, while the medusa form is a free-swimming, bell-shaped structure that reproduces sexually. This alternating life cycle allows for genetic diversity and adaptation to different environmental conditions.
What allows humans to have different traits?
Different alleles allow people to have different traits from each other.
Polymorphism in coelentrates?
polymorphism in coelentrates
What does ctenophores eat?
ctenophores eat jelly worms
Are coelentrates warm or cold blooded?
cold blooded. they live in the sea.
How do ctenophores differ from cnidarians?
Ctenophores are gelatinous creatures with rows of cilia for movement and lack stinging cells, while cnidarians have stinging cells called cnidocytes. Ctenophores also have a simpler body structure compared to the more complex body plans of cnidarians, which include jellyfish, corals, and sea anemones.
What is the name for the comb jellyfish?
Ctenophores (comb jellies) are a separate phylum from Cnidaria.
What are some economic importance of Ctenophores?
One of the common names for Ctenophores are coral, coral provide a good ecosystem for fish, some of the polyps on the coral reef are very good at photosynthesis causing plant and fish life to blossom.
What is phylum coelentrates all about?
It's talking about jellyfish, coral, sea anemones 2. Coelenterates mean ''hollow Inside''
What are pleurobancia?
Pleurobanchia* A genus of ctenophores having an ovate body and two long plumose tentacles.
How do ctenophores move?
Ctenophores are characterized by 8 ciliated rows used for locomotion. These cilia are stacked to look like a comb or "ctene". Therefore their name means comb bearer. They beat these ciliated rows in the water to propel themselves. However, they are subject to tides and winds.
How are sponges and coelentrates different?
Sponges are of the phylum porifera and are assymetrical invertebrates that have no true tissues due to a lack of cell specialization. Coelenterates are any of the phylum cnidariathat have radial symmetry and are invertebrates. Coelenterates include corals, sea anemones, jellyfish, and hydroids.

What are the harmful effects of Phylum Ctenophora?
Ctenophores are known for their ability to disrupt marine ecosystems by consuming large amounts of zooplankton, leading to imbalances in food webs. Additionally, some species of ctenophores have been introduced to new habitats through ballast water discharge, where they can outcompete native species and disrupt local ecosystems.
