Characteristics of Animals

18. Characteristics of Animals
1. They belong to the Domain Eukarya
Presence of Organelles

19. 2. They are Multicellular
Made up of multiple cells
Type of cells
- Somatic cell/body cell
- Reproductive cells/sex cells/gametes
Characteristics of Animals

20. 3. They are capable of locomotion.

21. They do not
produce their own
food.. In short, they
are consumers.
4. They are Heterotrophs

22. 5.Location of Organs (all main/vital organs are internal)

25. 6. Number of Parts and its locations are constant

26. 7. Faster and non-proportional response

29. Microscopy Is the science of magnification and resolution.
Anton Van Leeuwenhoek Discovered the simple microscope.

30. Microscopy
 Total magnification = Ocular magnification x
objective’s magnification
 Scanner = 4x
 Low power = 10x
 Middle Power = 40x
 High Power = 100x

42. Branches of Zoology
Study of Heredity and variation.
Genetics
Heredity - is the mechanism of transmission of genes
from parents to offspring.
Genes - are DNA molecules that determine the
characteristics of the organisms.

Taxonomy

45. Branches of Zoology
is the study of classifying organisms
with highly emphasis on
phylogenetic relationship and
complexity.
Systematics

Ecology

49. Branches of Zoology
study of organisms based on
their natural habitat.
Natural History

50. Branches of Zoology
Paleontology
Fossils - ancient remains or evidence
(imprints) of the organisms that live in the past
and deposited in the rocks or minerals.
study of fossils.

51. Branches of Zoology
study of worms.
Helminthology
Worms - are legless that can be flat, round or segmented.
Phylum Platyhelminthes - flatworms ex: Planaria, Liverfluke and
Tapeworm
Phylum Nematoda (Aschelminthes)- Roundworms ex: Pinworm,
Ascaris, Whipworm and Trichina worm
Phylum Annelida - Segmented worms ex: Bristleworm,

53. Branches of Zoology
Malacology
Mollusks - are soft-bodied shelled animals. It
has mantle that produces Calcium
carbonates and protein to form the shell.
Ex: Chitons, Squid, Octopus and Bivalves.
study of mollusks.

54. Examples of Mollusks

55. Branches of Zoology
Entomology
Insects - six-legged organisms, consists of three body
regions (Head, thorax and abdomen)
Ex: Cockroach, House fly, Mosquito, Honeybee
study of insects.

57. Branches of Zoology
Arachnology
Arachnids - eight-legged organisms, consists of two
body regions (Cephalothorax and abdomen)
Ex: Spider, Scorpions, ticks and mites.

Animal parasitology
Parasites – organisms that harm its host.
Ex: Head louse, parasitic worms such as
flatworms and nematodes.

60. Ichthyology
Branches of Zoology
Fishes have dermal scales and aquatic organisms (gills are
examples of adaptation)
Jawless fishes (Ancestral Jawless Fishes) Ex: Hagfish and Lampreys
Chondrichthyes (cartilagenous fishes)placoid as dermal scales.ex:
Sharks and rays
Osteicthyes (Bony fishes) dermal scales as dermal outgrowth. ex:
Bangus and Tilapia
study of Fishes.

61. Herpetology
Branches of Zoology
Amphibians - no epidermal outgrowth, thin and moist skin resulting to
capability of cutaneous respirations and can live terrestrial and
aquatic. Ex: Frog and Salamander
Reptiles - scales are epidermal outgrowth (scute, one set of scale) and can
also live terrestrial and aquatic.
Ex: Crocodile and Turtle
study of Reptiles and Amphibians.

62. Ornithology
Branches of Zoology
Birds - feather as an epidermal outgrowth (Wings
adaptation to fly), warm-blooded
organisms and can live terrestrial & aerial.
Ex: Native Chicken, King Penguin and Barn
owl.
