Is it an animal

Is it an animal?

• Number your paper 1-18 leave a space between
  numbers.
• For each picture, write the name of the organism
  and decide Is it an animal?
• Give 1 reason why or why not.

Which ones are animals?

• Everything BUT 6, 9, 18
• Any ones you want to review?
• So what is an ANIMAL?

21
Kingdom Animalia

• What is an animal?
• Multicellular
• Heterotrophic
• Aerobic
• Reproduce sexually
• Develop from embryos
• Motile at some time

22
What determines an animals complexity?

• Presence of body cavity - Coelom
• Organ systems
• Symmetry
• Cephalization
• Embryonic development
• Specialization of tissues
• Segmentation

23
Early Development

• Protostome- blastula developes into the mouth
• Deuterostome- blastula develops into the anus
• Chordates and Echinoderms (more advanced
  organisms) are deuterostomes

24
Figure 32.7 A comparison of early development in
protostomes and deuterostomes
25
Specialized Cells and Germ Layers

• As organisms get more advanced they have more
  cell specialization, tissues, and organs
• More advanced organisms have three germ layers
• Ectoderm- Outside Layer
• Mesoderm- Middle Layer
• Endoderm- Inner layer

26
Coelom

• Coelom- Body Cavity where organ development may
  occur
• 3 Types

27
Body Symmetry

• Asymmetry- no specific shape
• Radial Symmetry- Symmetry along and plane around
  an organism
• Bilateral Symmetry- A single imaginary plane
  could divide the organism in two

Asymmetry (no symmetry)
28
Segmentation

• Separate segments (parts) to an organism

29
Cephalization

• Concentration of sense organs and nerve cells in
  the front of the body

30
So what is an Invert? A Vert?

• Invertebrate lacking vertebrae spinal cord
  with bony covering
• Vertebrate those in Phylum Chordata with bony
  covering around a spinal cord

31
Invert/Vert OverviewKingdom Animalia

• Phylum Porifera -sponges
• Phylum Cnidaria -jellyfish, sea anemones
• Phylum Platyhelminthes -tapeworms, flukes
• Phylum Nematoda -pinworms, Ascaris
• Phylum Mollusca -clams, squid, octopi
• Phylum Annelida -earthworms, leeches
• Phylum Arthropoda -insects, crayfish
• Phylum Echinodermata -starfish, sand dollars
• Phylum Chordata (VERT) -fish, amphibians,
  reptiles, birds, mammals

Some Weird Animal Facts

• If you'd put all insects on one side of a balance
  and all the rest on the other side of the
  balance, the insects would outweigh the rest.
• Scientists found out how bees communicate. Bees,
  however, are not able to learn a foreign
  language. That is, Egyptian bees do not learn how
  to communicate with European bees.
• Butterflies have 12,000 eyes. They fly with an
  average speed of 32 km/h. Swordfish, meanwhile,
  can reach up to 110 km/h.
• Some moths use acoustic countermeasures to
  scramble the bat's sonar.
• Snails can remain dormant for up to three years.
• The honeysucker (aka the honey-eater, classified
  in the phylum Chordata, subphylum Vertebrata,
  class Aves, order Passeriformes, family
  Meliphagidaeis) is the only bird that can
  actively fly backwards. They cannot, however,
  walk.
• Crocodiles kill on average 2,000 people per year.
• In the last 4,000 years, no new animal has become
  domesticated.
• Humpback whales keep composing new songs, and
  sing old ones rarely.
• Giraffes have no voices.
• Elephants cannot jump.
• Gorillas can't swim. Cats can, though they do not
  traditionally like water.
