Study Notes

Invertebrates

Invertebrates are animals lacking a vertebral column.
They encompass a vast array of species with diverse characteristics.
They are broadly classified into various phyla, each with its distinctive features.

Animal Phylogenetic Tree

The ancestral protist gave rise to the Metazoa.
Metazoa, further branched into those with tissues (Eumetazoa) and those without tissues (no tissues).
Eumetazoa branched into Radiata (radial symmetry) and Bilateria (bilateral symmetry).
Bilateria further split into three main branches: Lophotrochozoa, Ecdysozoa, and Deuterostomia.
Each branch exhibits distinctive characteristics and evolutionary relationships.
The tree depicts the evolutionary history and relationships among various animal groups.

Phylum Porifera (Sponges)

Sponges are the simplest multicellular animals.
They lack tissue differentiation.
They exhibit a variety of shapes and sizes.
Sponges have specialized cells: choanocytes, amoebocytes, and epidermal cells.
They primarily filter-feed.
Water drawn into the spongocoel, filtering through choanocytes.
Amoebocytes distribute nutrients..

How Sponges Make a Living

Sponges are suspension feeders.
Water is drawn into the spongocoel.
Filtering happens by choanocytes
Food particles are phagocytized by amoebocytes.
Nutrients are distributed throughout the sponge.
Sponges lack a circulatory system, relying on diffusion.

Phylum Ctenophora (Comb Jellies)

Ctenophores are diploblastic.
They display radial symmetry.
They feature a unique gastrovascular cavity (modified).
They have eight rows of cilia for locomotion.
They possess tentacles with colloblasts for capturing prey.

Phylum Cnidaria

Cnidarians are diploblastic, with radial symmetry.
They exhibit a gastrovascular cavity.
They include sea anemones, corals, hydras, and jellyfish.
They have specialized stinging cells called cnidocytes—containing nematocysts.
They exhibit two body forms: polyps and medusae.
Cnidarians demonstrate alternation of generations.
Their life cycle exhibits asexual and sexual reproduction.

Complete vs. Incomplete Digestive Tracts

Incomplete digestive tracts (e.g., cnidarians) have a single opening, serving as both mouth and anus.
Gastrovscular cavity for digestion.
Diffusion for exchange of nutrients.
Complete digestive tracts (more complex) have two openings, a mouth, and an anus, facilitating sequential digestion and nutrient absorption.

Other Invertebrate Phyla (Summary)

Phylum Platyhelminthes are flatworms, which are triploblastic acoelomates with a gastrovascular cavity.
They include free-living and parasitic species.
Phylum Mollusca encompasses snails, slugs, clams, and other shelled creatures.
They have a soft body typically protected by a shell.
They possess a coelom around the heart and hemocoel.
Phylum Annelida features segmented worms, each with a closed circulatory system and a coelom.
Phylum Nematoda comprises roundworms, possessing a hemocoel and an exoskeleton.
Phylum Arthropoda encompasses insects, crustaceans, and spiders.
They are characterized by a hard exoskeleton, jointed appendages, and a distinctive body plan.
Phylum Echinodermata (e.g., starfish, sea urchins) have radial symmetry as adults, but bilateral larvae.
They possess an endoskeleton and a water vascular system.
