Arthropods*

*There are four sub-groups of Arthropods: Insects, Arachnids, Crustaceans, and Centipedes & Millipedes

They belong to the class Anthozoa.

Sea urchins are purple, red, orange, yellow/orange, and a mix of red and purple.(Sea Urchins come in many shapes sizes and colors.)

They both have a large opening through which water flows allowing them to suspend food particles from the water. Their tentacles aid in their ability to propel water towards these openings, increasing their food intake.

I'm not quite sure what a 'clown anemone' is, i researched it but the only things i found were on clownfish or anenomes. Maybe you were meaning clownfish?? If so here is some info i found about clownfish, sorry if this is not what you were meaning, but hey, you might learn something new anyway! (i sure didn't know all this stuff about clownfish!)

Scientific name: Amphiprion species

Country: Worldwide tropical

Continent: Oceania, Asia, Africa, South America, Central and North America

Diet: Algae, crustaceans, molluscs

Food & feeding: Omnivore

Habitats: Ocean

Conservation status: Not Threatened

Relatives: Thread-fin damselfish

While sea urchins are slow and non-aggressive, they do have spines for a reason. Some sea urchins possess venomous spines, sharp enough to pierce through a diving suit. This venom can cause muscle spasms, faintness, difficulty breathing and death.

Leeches produce egg cocoons which are laid in moist environments. Parents may provide some level of protection to the eggs until they hatch, but typically there is no further care given to the young once they are born. The young leeches must fend for themselves to find food and survive.

As hermaphrodites, leeches have both male and female sex organs. Like the earthworms they also have a clitellum, a region of thickened skin which is only obvious during the reproductive period. Mating involves the intertwining of bodies where each deposits sperm in the others' clitellar area. Rhyncobdellids have no penis but produce sharp packages of sperm which are forced through the body wall.

A lot of sea anemones have a facultative ectosymbiotic relationship with zooxanthellae and/or zoochlorella. Obviously these need light to carry out photosynthesis, and so in that sense yes, they do need light. However it is not really the anemone that needs the light, it's the algae and the anemone can survive without the algae, so in that sense no, they don't need light. It depends on what you meant by the question.

Diatoms can be found in oceans, freshwater, and also in soils on damp surfaces

"Proh-BAH-sihss" -- which also may be heard said "proh-BAH-skihss" -- is a way of pronouncing the word "proboscis." The word refers to an elongated snout on an elephant and a sucking mouthpart on an invertebrate.

Cnidarians are found in marine environments, particularly in coral reefs, rocky shores, and ocean floors. They can also be found in freshwater habitats like lakes and rivers.

There are many orders of sea urchins. The ones in the Subclass Euechinoidea go like this: Superorder Atelostomata - Orders Cassiduloida and Spatangoida; Superorder Diadematacea - Orders Diadematoida, Echinothurioida, and Pedinoida; Superorder Echinacea - Orders Arbacioida, Echinoida, Phymosomatoida, Salenioida, and Temnopleurioda; Superorder Gnathostomata - Orders Clypeasterioda (sand dollars) and Holectypoida.

Honey typically takes the longest to spoil out of the three options you listed (cashew, pasta, honey). Honey has a very long shelf life due to its low water content and natural acidity, making it resistant to spoilage. On the other hand, cashews and pasta have a higher moisture content and are more prone to spoilage compared to honey.

Invertebrates play crucial roles in ecosystems as predators, prey, decomposers, pollinators, and more. Their diverse functions help maintain the balance of ecosystems and support the survival of various species, including vertebrates. Without invertebrates, many ecosystems would collapse, leading to cascading effects on biodiversity and overall ecosystem health.

Sea urchins have a hard shell called a test that protects their soft inner body. They also possess tube feet that help them move and cling to surfaces. Sea urchins are able to feed on algae and organic matter using a specialized feeding structure called Aristotle’s lantern.

To make a model of a sea urchin, you can start by shaping a round sphere out of clay or paper mache to represent the body. Then, attach smaller spheres or spiky shapes around the main body to represent the spines. Paint the model in appropriate colors and add any other details as needed.

No way. Predation benefits the symbiont and harms (kills) the host, or prey. In parasitism, the host may not die, but the symbiont still lowers the host's fitness by, for example, leeching nutrients or blood off of the host.

Mutualism is when both the host and symbiont benefit.

Diatoms are believed to have originated during the Jurassic period, around 250 million years ago. They are a type of algae that adapted to live in both freshwater and marine environments, and have since become one of the most diverse and abundant types of phytoplankton in the world.

If your garden is not too big, use baiting technique, that means you are the "Bait", when they come to you, just use forceps to pick them up and soak them in the salt water (50g/100ml) to kill them.

Non-vertebrate animals play important roles in ecosystems, such as pollination, decomposition, and nutrient cycling. They also contribute to biodiversity and provide valuable resources for humans, such as food and medicine. Additionally, studying non-vertebrate animals can help us better understand evolutionary processes and biological systems.

A Didinium is a protist that feeds by ingesting bacteria (bacteriovorus) through a mouth-like opening at the anterior end of the cell. The cell has an equatorial gridle of cilia, with a second gridle surrounding the anterior end. Cilia may assist in sweeping bacteria toward opening.

Some examples of platyhelminthes, also known as flatworms, include planarians, flukes, and tapeworms. Planarians are free-living flatworms found in freshwater environments. Flukes are parasites that can infect various animals, including humans. Tapeworms are also parasitic and can be found in the intestines of vertebrates.
