2019年8月19日 · An acoelomate is an animal that does not possess a body cavity. Unlike coelomates (eucoelomates), animals with a true body cavity, acoelomates lack a fluid-filled cavity between the body wall and digestive tract.
Acoelomate - Definition, Examples, Quiz - Biology Dictionary
2020年1月9日 · An acoelomate is the simplest form of animals which have 3 true tissues. These tissue are the endoderm , mesoderm , and ectoderm , in that order from inside to out. In an acoelomate, these tissues touch back-to-back, without any space in between.
Acoelomates - Examples of Acoelomate Animals - BYJU'S
Animals that have their body cavities filled with fluid are called eucoelomates or coelomates. Their internal organs are suspended in the fluid cavity. Examples include arthropods, annelids, molluscs, hemichordates, echinoderms and chordates. Acoelomates do not have a fluid-filled coelomic cavity. Example – Platyhelminthes.
Acoelomate Definition & Meaning - Merriam-Webster
The meaning of ACOELOMATE is an invertebrate lacking a coelom; especially : one belonging to the group comprising the flatworms and nemerteans and characterized by bilateral symmetry and a digestive cavity that is the only internal cavity.
Coelomates, Acoelomates, and Pseudocoelomates
Animals in which the coelom is lined by the mesoderm are known as coelomates while those in which the cavity is absent are called acoelomates. In some metazoans, the body cavity is not entirely lined by mesoderm (the endothelial lining found in coelomates). For this reason, they are referred to as pseudocoelomates (do not have a true coelom).

Acoelomata ** Definition, Examples, Vs Pseudocoelomate
Essentially, Acoelomata is a subdivision (or super-phylum) that consists of animals without a true body cavity. Also known as a coelom, the body cavity is a fluid-filled space located between the body wall and the digestive tract.
Coeloms and Pseudocoeloms | Body Cavities Explained - Earth Life
2020年2月18日 · Acoelomate animals are called acoelomates and they have no true body cavity. The acoelomate phyla are Placozoa, Porifera, Cnidaria, Ctenophora, Platyhelminthes, Mesozoa, Nemertina, Gnathostomulida. Pseudocoelomate animals have a pseudocoelom. They have a body cavity, but it is not lined with mesodermal cells.
Acoelomate vs. Coelomate - What's the Difference? | This vs. That
Acoelomates and coelomates are two types of animals that differ in their body cavity structure. Acoelomates, as the name suggests, lack a true body cavity. Instead, their organs are embedded in solid tissue. This lack of a body cavity limits their size and complexity.
