What are some members of the class Anthozoa?
What are some members of the class Anthozoa?
Anthozoans include sea anemones, sea pens, and corals.
What are the characteristics of Cubozoa?
The most obvious characteristic of cubozoans is the box-like shape of their bell. The manubrium and mouth are located inside the bell, and the velarium is along the edge of the bell. Pedalia are muscular extensions of the bell and the tentacles are attached to the pedalium.
What is the dominant form of Anthozoa?
medusa
Class Scyphozoa– the medusa stage is dominant and polyps are rarely formed. This class is composed primarily of the jellyfishes. Class Anthozoa– large, often elaborate polyps or colonies of polyps form.
How many anthozoa species are there?
6,000 species
Anthozoa is the largest of the four classes of Cnidaria with over 6,000 species (France 2004). They are found worldwide in all oceans, from the Arctic to the Antarctic. Anthozoa means “flower animals,” which is descriptive of this class of invertebrates.
How does the life cycle of the anthozoa differ from that of other animals within the Cnidaria?
Unlike other cnidarians, anthozoans do not have a medusa stage in their development, they live exclusively as polyps throughout their life cycles. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows.
Are Anthozoa sessile?
The anthozoans, the sea anemones and corals, are all sessile species, whereas the scyphozoans (jellyfish) and cubozoans (box jellies) are swimming forms. The hydrozoans contain sessile forms and swimming colonial forms like the Portuguese Man O’ War.
What is the classification of Anthozoa?
The Class Anthozoa includes a variety of animals that have polyps with a flower-like appearance. In these forms, the gastrovascular cavity is large. It is divided by walls or septa, which arise as folds from the body wall.
What is the gastrovascular cavity of Anthozoa?
The Class Anthozoa includes a variety of animals that have polyps with a flower-like appearance. In these forms, the gastrovascular cavity is large. It is divided by walls or septa, which arise as folds from the body wall. These folds, along with the mouth and pharynx, are usually arranged in a biradially symmetric pattern.
What is the classification of Anthopleura sola?
Similar species: Anthopleura sola is nearly as large but darker green in color with distinct radiating lines on oral disc. Phylum Cnidaria, Class Anthozoa, Subcl. Zoantharia, Order Actiniaria, Family Actiniidae
What happens when a plant respire anaerobically?
In these states, the roots of plant respire anaerobically making alcohol. This can kill the plant. Germinating seeds during the early stage respire anaerobically as they have seed coat which does not permit the oxygen to enter through it. Respiration in plants occurs throughout the day and night thereby carbon dioxide is formed.
