What type of body cavity do mollusks have?
Annelids exhibit bilateral symmetry.
What are annelids?
Annelids are a type of segmented worms found in marine, freshwater, and terrestrial habitats. They have a cylindrical body with ring-like segments and exhibit bilateral symmetry. Examples of annelids include earthworms, leeches, and marine bristle worms.
Where might you find annelids?
annelids are commonly found in wet or moist environment's
What type of support system do annelids have?
Annelids have a hydrostatic skeleton, which is a system of fluid-filled compartments surrounded by muscle tissue. This system helps provide support to their bodies and allows for coordinated movement. Additionally, some annelids also have setae, which are bristle-like structures on their bodies that aid in gripping surfaces for movement and support.
Is hydrostatic skeleton a form or type of skeleton?
Yes, a hydrostatic skeleton is a type of skeleton found in certain invertebrates that uses fluid-filled compartments to provide support and structure to the body. It relies on the pressure of the enclosed fluid to maintain body shape and movement.
What is annelid phylum?
The annelid phylum consists of segmented worms, which have bodies made up of repeated segments called metameres. Annelids typically have a fluid-filled cavity called a coelom that serves as a hydrostatic skeleton for movement. They can be found in marine, freshwater, and terrestrial environments around the world.
A true digestive tract is found in?
Annelids
Parapodia are found on what type of annelids?
Parapodia are found on polychaete annelids, which are marine worms characterized by their numerous bristle-like extensions called chaetae on each body segment. These parapodia aid in locomotion and respiration.
What type of skeleton is similar to a filled water balloon?
An invertebrate skeleton, such as a hydrostatic skeleton found in some soft-bodied animals like jellyfish and worms, is similar to a filled water balloon. This type of skeleton uses fluid pressure to provide support and structure to the body.
What kind of symmetry type do annelids have?
Bilateral symmetry
What continents and oceans do annelids live on or in?
Annelids are found worldwide in moist or wet environments ranging from marine habitats to moist soil.
Does a slug worm or jellyfish have a skeleton?
They have a type of skeleton called a hydrostatic skeleton. This type of skeleton is a fluid filled sac which is surrounded by muscles.
