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.
