From what animal group did arthropods evolve?
It is not likely that the annelids evolved from the arthropods is as much as they are the much simpler of the two groups of organisms. The arthropods have a well developed open circulatory system, segmented muscles and a complex nervous system (including eyes and chemoreceptors, the antennae) and an exoskeleton.
Are arthropods parasites?
No. Leeches are annelids, also known as segmented worms.
What evedince suggest that arthropods might have envovled from annenlids?
Annelids are segmented in much the same way as arthropods (think of earthworms). Primitive arthropods include centi- and millipedes, with many unspecialized legs (legs in more advanced arthropods often specialized to form antennae, mandibles and pedipalps), and they're as long and thin as segmented worms. Also, there's a possible 'intermediate form', Peripatus, the velvet worm, being long, thin and soft-skinned, but also having many stubby legs!
Are sanddollars arthropods?
no, i dont know what they are, but they are not arthropods
Are earthworms insects?
No they are not. They do not have 6 legs. They are part of a phylum called Annelida. In that phylum they are in a class called Clitellata. In contrast, insects are part or the phylum Arthropoda and the class Insecta,
What is the evolutionary relationship of arthropods and annelids?
Arthropods have shells designed for protection while annelids do not.
What do annelids and arthropods have?
Segmented Bodies
Are scorpions annelids flatworms mollusks arthropods cnidarians or echinoderm?
a scorpion is a Arthropods
Which groups of invertebrates are protostomes?
Flatworms, Roundworms, Annelids, Mollusks, and Arthropods
What are annelids mollusks and arthropods classified as?
Annelids, mollusks, and arthropods are classified as invertebrates, which are animals lacking a backbone. They belong to the larger group called Coelomates, characterized by having a true coelom, a fluid-filled body cavity. Annelids are segmented worms, mollusks include diverse organisms like snails and octopuses, and arthropods encompass insects, arachnids, and crustaceans, all distinguished by their body structures and developmental processes.
Name 3 invertebrate groups?
3 of the water invertebrate groups are the annelids, arthropods and crustacean.
What evidence suggests that Arthropoda might evolved from Annelids?
Annelids include earthworm,leeches and nereis;arthropods include mainly insects.THe relations between them is that both are triploblastic,coelomates,segmented body,bilateral symmetry and oviparous type of reproduction.
Is a millipede is a worm?
No. Millipedes are myriapods, meaning "many feet". Centipedes are also myriapods. Segmented worms are annelids; earthworms and leaches belong to this group. Also, myriapods are arthropods; annelids are not.
What is the difference between monecious and dioecious in mollusks and annelids?
monecious is when it has male and female reproductive organs in the same organism.
Which type of animals are believed to have involved from segmented worms?
The arthropods (for instance, centipedes) are believed to have descended from the annelids (segmented worms).
What are the invertebrate groups?
The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
What are two organisms that have segmented body plans?
The types of organisms which have segmented bodies include annelids, arthropods, echinoderms, and chordates. Some of the most obvious examples of segmentation are found in insects which belong to the arthropods.
