Annelids exhibit bilateral symmetry.
What are four characteristics that complex animals tend to have?
Complex animals tend to have specialized cells, bilateral symmetry, cephalization, and a body cavity.
What are the characteristics of PLATYHELM?
Platyhelminthes, commonly known as flatworms, are soft-bodied invertebrates with a flattened body shape. They exhibit bilateral symmetry and lack a coelom (body cavity). They are hermaphroditic, meaning they have both male and female reproductive organs.
What type of body cavity does a jellyfish have?
Pisces or fish have true internal body cavity.
Why is the oral cavity not an internal body cavity?
Probably because you can visualize the same from out side. You can list the same in internal body cavity and you wont be wrong. Mostly because the mouth and the anus both lead to the external environment.
What kind of symmetry does annelida have?
Annelids exhibit bilateral symmetry, meaning they can be divided into two equal halves along a single plane. This symmetry allows for efficient movement and body organization in these segmented worms.
Brittle star coelom type?
Brittle stars have a complex coelomic system, consisting of a spacious coelomic cavity that accommodates their internal organs. This coelomic system aids in internal transport, support, and protection of organs.
What type of body cavity do mollusks have?
Annelids exhibit bilateral symmetry.
Flatworms are soft flattened worms that have tissues and internal what?
Flatworms have tissues and internal organs. They belong to the phylum Platyhelminthes and are characterized by their bilateral symmetry and lack of a coelom (body cavity). Their internal structures include a digestive system, nervous system, and reproductive organs, allowing them to perform various physiological functions.
What are five characteristics of cnidarians?
1) cnidarians have bilateral symmetry, 2) there are 2 different forms(dimorphism) , a medusa and a polyp, 3) reproduction is asexual or sexual. 4) they have cnidoblasts, special cells that contain nematocysts, the cells that sting, and 5) they have an internal cavity, and a mouth where food comes in and out. digestion is extracellular.
What are four characteristics that complex animals tend to have?
Complex animals tend to have specialized cells, bilateral symmetry, cephalization, and a body cavity.
What traits occur on the phylogeny at the same time as bilateral symmetry?
One of the primary traits that appears in the phyla Bilateria is the presence of a body cavity. That is, there are three distinct layers of cells, the endoderm, mesoderm and ectoderm.
What parasite has bilateral symmetry and pseudocoelom found in humans?
The parasite that exhibits bilateral symmetry and has a pseudocoelom in humans is the pinworm, scientifically known as Enterobius vermicularis. This small nematode is commonly found in the intestines of humans, particularly in children, and is known for causing enterobiasis, which leads to itching around the anus. The pinworm's body structure, including its segmented appearance, contributes to its classification within the nematodes, which are characterized by their pseudocoelomic body cavity.

What are facts about mollusk worms?
this is what i know of mollusk: soft bodies (some have shells) true coelum/body cavity - advanced organs bilateral symmetry examples: octopuses, cuttlefish, muscles/clams/oysters muscular FOOT for movement that should definitely answer your question
In what way the development of a body cavity or coelom an advantage for bilaterally symmetrical animal?
animals with bilateral symmetry can find food and mate es and avoid preditors because they have sensory organs and good muscle control. ex of these types of animals would be a human
What are some general features of acoelomate animals?
Some of the general features of acoelomate animals include internal cavity for digestion, bilateral symmetrical, organ system organization and so on. These features are the ones that distinguish acoelomate animals.
