What are the characteristics of 8 groups of invertebrates?
the 8 groups of invertebrates are the arthropods, poriferans, platyheminthes, coelenterates, nematoeds, mollusks, echinoderms, and annelids
What are some characteristics of echinoderms?
they are in the shape of a star
What are the characteristics tha distinguish echinoderms from other phyla?
their body plan
What is the groups of invertebrates?
sponges+mollusks+arthropods+worms+octopods+echinoderms
Why are Echinoderms considered to be closely?
Echinoderms are considered closely related to chordates due to their shared developmental features, such as the presence of a deuterostome developmental pattern, where the anus forms before the mouth during embryonic development. Additionally, both groups exhibit similarities in their genetic and molecular structures, particularly in their Hox gene arrangements. These characteristics suggest a common evolutionary ancestor, highlighting the evolutionary connection between echinoderms and chordates.

What are the four main groups of eukaryotes?
The four main groups of eukaryotes are plants, animals, fungi, and protists. These groups encompass a wide variety of organisms with different characteristics and modes of life.
What are the groups of echinoderms?
Sea stars, brittle stars, sea urchins, and sea cucumbers.
What are all of the invertibrate groups?
An invertebrate is an organism that lacks a backbone. The 6 groups of invertebrates are sponges, cnidarians, worms, mollusks, echinoderms and arthropods.
Which invertebrates are also deuterostomes?
Invertebrates that are also deuterostomes include echinoderms and hemichordates. Echinoderms, such as starfish and sea urchins, are characterized by their radial symmetry and a water vascular system. Hemichordates, which include acorn worms and pterobranchs, share some developmental characteristics with chordates. Both groups exhibit the deuterostome embryonic development pattern, where the anus forms before the mouth.
What are the five main groups of materials?
The five main groups of materials are metals, polymers, ceramics, composites, and semiconductors. Each group has unique properties and characteristics that make them suitable for different applications in various industries.
How many species of echinoderms are there?
Approx. 7, 000 species that fall into five clades(sub-groups)
