Transcript of Biology Report (Kingdom Animalia)
exhibit sexual reproduction
Non - Bilaterals
presence or absence of spine
based on the form symmetry
animals with this form of symmetry have ½ of its body as a mirror image of its other half
Posterior (back surface)
Anterior (front surface)
Dorsal (top surface)
Ventral (bottom surface)
animals with this form of symmetry have bodies arranged around a central axis
animals with this form of symmetry have no front or back, no left or right.
the arrangement of the body parts around a center point or line.
* "Porifera" comes from a Latin word meaning “pore-bearers”
* organisms under this phylum have bodies that are covered with numerous pores.
are marine animals that possess stinging cells called cnidocytes
have sac-like cavities and long flexible tentacles
reproduce sexually or asexually
All chordates possess the following structures at certain stages in their life cycle:
a nerve cord
Marine animals that are not found in freshwater
Move using a water-vascular system that is controlled by muscular action
They lack a brain and complex sensing organs.
Some species have the capacity to regenerate lost parts like a cut arm.
The term “mollusk” describes the soft body of the organisms in this phylum.
Most mollusks have shells that are composed mainly of calcium carbonate.
The Visceral Mass
their name comes from the Greek words “arthro” means “jointed” and “poda” means “foot”.
have jointed legs, segmented body, and an exoskeleton
3 Distinct Parts
The term annelida was derived from the Latin word annulus, means “ring”.
Their bodies consist of repeating ringlike segments called metamerism.
got their name from the Greek words platy, meaning “flat” and helminthes meaning “worm”
lack circulatory and respiratory systems
they have round, elongated bodies
have round bodies covered with a tough cuticle that tapers on both ends
most nematodes are parasitic
Skin covered in scales
Ectothermic , cold blooded
Soft shelled eggs that must be laid in water
Limbs modified into fins
Gas exchange through gills
amphibian means “dual life”.
vertebrates whose young live in water but the adults live on land.
have skeleton and powerful legs for movement on land as well as in water.
adult amphibians breathe mainly through a sac-like lung.
a circulatory system with a 3-chambered heart moves blood to and from the lungs
cold-blooded or exothermic animals
have an amniotic egg, which usually has a leather hard shell that protects the embryo from drying out.
terrestrial reptiles live on semi-deserts while crocodiles, alligators and some species of turtles live on places near waterforms.
produce amniotic eggs but usually give them greater protection from predators
have feathered wings that enable them to fly.
are warm-blooded, have a four-chambered heart, a break or bill, and light bones.
their bones are lightweight and filled with air.
air sacs are found throughout the body.
they lack teeth but their jaws are covered by a horny beak
have two pairs of limbs; the forelimbs are modified wings while the hind limbs are for perching, hopping or swimming and catching prey.
derived from the word mamma, meaning, “breast”
conceive their young within the reproductive tract of the mother
mammals are warm-blooded , have a diaphragm, body hair and have four-chambered hearts.
most are viviparous and they all exhibit parental care
well-developed brains that enable them to adapt to their environment and are the only animals that have an outer ear that collects sound and transmits it to the middle ear and inner ear
