the same as the genus of an animal that steals chloroplasts from algae. It can keep the chloroplasts alive for many months, thanks to genes that were originally part of the algae genome. What kind of animal is this? A. Luna both caterpillars, Insecta, Arthropod B. Marine Flatworm, platyhelminthes C. Sea slug, mollusk gastropod D. Bivalve, Mollusk
Animal Diversity
Nematodes are commonly known as roundworms. They are free-living, very tiny organisms. They have an elongated and tubular body. These organisms have a nervous system and are mostly act as parasites to both animals and plants.
Platyhelminthes
Platyhelminthes are also known as "flatworms" because as they are dorsoventrally flattened from head to tail. They are invertebrate, soft-bodied, acoelomate, unsegmented and have bilateral symmetry.
Arthropod: Invertebrates with an exoskeleton, segmented bodies, and paired jointed legs are known as arthropods. Arthropods belong to the Arthropoda phylum. Their limbs are jointed, and their cuticle is formed of chitin, which is often mineralised with calcium carbonate. Arthropods can feed in a variety of ways. There are specialisations within these major categories, such as carnivores, herbivores, detritus feeders, filter feeders, and parasites.
Platyhelminthes: Any member of the phylum Platyhelminthes, a group of soft-bodied, usually greatly flattened invertebrates, is known as a flatworm. Although certain flatworm species are free-living, roughly 80% of all flatworms are parasitic, meaning they live on or in another organism and feed off of it. Flatworms with a simple ciliated pharynx can only eat protozoans and rotifers, while those with a muscular pharynx may turn it outward, shove it through the tegument of annelids and crustaceans, and extract their internal organs and fluids.
Mollusk: After the Arthropoda, Mollusca is the second-largest phylum of invertebrate animals. Molluscs or mollusks are the members of this group. Molluscs are estimated to number around 85,000 species. Between 60,000 and 100,000 additional species are thought to exist in the fossil record. Mollusks are soft-bodied invertebrates belonging to the phylum Mollusca, with a calcium carbonate shell secreted by a soft mantle enveloping the body. The majority of mollusks are herbivores that feed on algae or filter feeders. There are two main feeding options for those that graze. Some eat minute filamentous algae and use their radula as a rake to gather filaments from the seafloor.
