What is the purpose of the tentacles of coral polyps?
They trap tiny particles of food as they drift by.
How do polyps swim?
polyps are sessile, therefore they do not move
What are the parts of a Portuguese man - of - war?
The Portuguese man-of-war is made up of four interconnected parts: the pneumatophore (float), tentacles, digestive polyps, and reproductive polyps. The tentacles are used for capturing prey, while the digestive and reproductive polyps help with digestion and reproduction respectively. The float allows the organism to float on the ocean's surface.
What is the purpose of the tentacles on a jellyfish?
To capture prey.
What are the two forms of cnidarians?
Cnidarians come in two forms: a medusa has tentacles that hang down and polyps usually live attached to a surface.
What is the soft part of the Great Barrier Reef made of?
The Great Barrier Reef is made up of both hard corals and soft corals. The term 'soft coral' is the name given to the coral group with the scientific name of Alcyonacea. They are different from hard coral polyps, which have multiples of six tentacles, by the fact that the soft coral polyps always have eight tentacles.
What are ten coral reef plants?
Coral is actually not a plant. Corals are colonies made up of tiny animals called polyps. Hard corals have polyps with 6 tentacles, or multiples of 6 tentacles. Soft coral polyps have 8 tentacles. Ten species of corals are Favia, Goniopora, Hydnophora, Echinophyllia, Tubinaria, Acropora, Staghorn, Brain, Fan, and Elkhorn. Ten plants that are found in coral reefs are Halophila ovalis, Halodule uninervis, Zostera capricorni, Trichodesmium, coralline algae, Sargassum, Turbinaria, Sea lettuce (Ulva), sea grapes (Caulerpa) and turtle grass (Chlorodesmis).
Compare the body forms of a polyp and medusa?
Polyps and medusae are two distinct body forms of cnidarians. Polyps are typically cylindrical and sessile, with a mouth and tentacles facing upward, anchored to a substrate. In contrast, medusae are free-swimming and have an umbrella-shaped, bell-like structure, with the mouth and tentacles hanging downward. This differences in morphology reflect their adaptations to different lifestyles within their life cycle, with polyps often engaging in asexual reproduction and medusae primarily involved in sexual reproduction.
Explain the difference between a polyp and a Medusa?
A polyp is anchored to substrate, like a rock or piece of coral. Anemones are polyps. They catch food with their tentacles and have the mouth on the upside. A medusa is swimming freely. Jellyfish are medusa stages. They catch food with their trailing tentacles and have the mouth on the downside. You can view polyps as the settled ´plant´ and medusa as the free-floating ´seed´, like in a dandelion. Though they aren´t plants at all, of course.
Is a free swimming form of a cnidarian called a polyp?
No, a free swimming form of a cnidarian is called a medusa. Polyps are typically attached to a substrate and have a cylindrical body with a mouth surrounded by tentacles at one end. Medusae have a bell-shaped body with tentacles hanging down.
Why is a Portuguese man of war considered to be a colony?
As with other siphonophores, a Portuguese Man'o'War is considered to be a "colonial" animal because the whole creature is made up of several polyps living together, including one enlarged and inflated polyp serving as the float, with several smaller polyps with long tentacles that catch prey to feed the entire colony.
What is made by tiny tube shape animals called polyps?
Polyps create calcium carbonate exoskeletons, forming the architecture of coral reefs. These exoskeletons accumulate and combine over time to create the familiar solid structures of coral reefs that we see in the ocean.
