Across
  1. 2. The level that groups animals like mammals, birds, and insects
  2. 3. The second most specific level in taxonomy that groups species
  3. 5. A class of warm-blooded vertebrates in the phylum Chordata, commonly known as birds. Members of Aves are characterized by feathers, beaks, and the ability to lay hard-shelled eggs. They also have lightweight bones that facilitate flight, though not all birds can fly.
  4. 7. A class of cold-blooded, vertebrate animals in the phylum Chordata, characterized by scaly skin and laying soft-shelled eggs on land. This class includes lizards, snakes, turtles, and crocodiles.
  5. 9. A phylum in the animal kingdom that includes animals possessing a notochord (a flexible, rod-shaped structure) at some stage in their development. This group includes vertebrates like mammals, birds, reptiles, and fish.
  6. 11. The system used to classify organisms based on shared characteristics
  7. 13. The level of taxonomy that divides classes into smaller groups (5 letters)
  8. 16. A class within the phylum Chordata that includes animals with characteristics such as hair or fur, mammary glands for feeding young, and a neocortex region in the brain. Mammals also give live birth, with few exceptions.
  9. 17. level that organizes organisms based on major body plans (6 letters)
  10. 18. group of related species (5 letters)
  11. 19. level that groups families within an order (7 letters)
Down
  1. 1. The two-part Latin name for an organism's genus and species (14 letters)
  2. 4. The most specific level of classification
  3. 6. Subdivides life further, such as animals (Animalia), plants (Plantae), fungi, and others
  4. 8. The kingdom of multicellular, eukaryotic organisms that are heterotrophic (they consume organic material for energy) and usually have the ability to move. This kingdom includes animals ranging from simple sponges to complex mammals.
  5. 10. A class of cold-blooded vertebrates in the phylum Chordata that typically live both on land and in water. Amphibians undergo metamorphosis from a larval stage (usually aquatic) to an adult stage (often terrestrial). Frogs, salamanders, and newts are examples of amphibians.
  6. 12. The most general category in taxonomy, with three major types: Archaea, Bacteria, and Eukarya
  7. 14. One of the three domains of life, Eukarya includes all organisms made of cells with a nucleus and other membrane-bound organelles. This domain includes animals, plants, fungi, and protists.
  8. 15. A tool used to identify organisms through a series of choices (10 letters)
