9 Phylas Part 1 Flashcards
The animal kingdom is composed of how many species?
Over 1.1 million named species
The animal kingdom is in groups called?
Phyla (singular form of phylum)
Characteristics::::
What kind of symmetry
Radial symmetry or Asymmetric
Asexual
Baby sponge buds off the side and eventually breaks off
Sexual
Gametes from male sponge released into water; finds female (fertilization happens inside of female)
Phylum Porifera(the sponges)
Name the three groups
1.) Asconoid sponges(simplest)
2.) Syconoid sponges(medium)
3.) Leuconoid sponges(most complex)
Characteristics::::
Oxygen is taken in by?
Simple diffusion
Characteristics::::
Filter feeders-??
No specific digestive organs
Skeletal structure
Protein/collagen fibers with calcium or silicon crystalline spicules
Phylum Cnidaria
Corals jellyfish sea anemones
Cnidarias phylum is what kind of symmetry
Radial or biradial
Phylum Cnidaria do they have respiratory organs yes or no
No
Cniadarias have 1 opening for
Food ingestion and waste excretion
Nematocysts
Aka cnidoblasts; specialized stinging cells used to capture and subdue prey
2 body types for the Cnidaria phylum
Medusa-free swimming
Polp-non moving
Reproduction:
Hermaphroditic-??
Produce both male and female gametes
Reproduction for Cnidarians
Asexual
Sexual
Budding -small buds are formed on adults
External fertilization
5 classes
Hydrozoa-hydra
Scyphozoa-jellyfish
Anthozoa-coral and sea anemone
Cubozoa-box jellyfish
Staurozoa-stalked jellyfish
Cephalization
the concentration of nervous structures and functions at one end of the body, in particular the head.
Cuticle
Thickened body covering
Pseudocoelomate
Intermediate body cavity (tube within a tube)
Cerebral ganglia
Nerve bundle (brain like)
Setae
External bristle like hairs on each segment
Septa
Internal walls separating each segment
Citellum
Saddle secretes a tube of mucus (cocoon) to encase the fertilized eggs
Bivalves
Clams, mussels, oysters
Gastropods
Snails, slugs
Cephalopods
Octopus,cuttlefish
Mantle
Thin membrane that secretes material needed to make the shells
Radula
Spiny type of tongue used for feeding
Chromatophores
Special cells on the surface; can change colors + textures
Ink sac
For defense against predators
Hectocotylus
Modified arm of the male
Cnidarias animals

Seastars
Cucumbers
Urchins
Exoskeleton
External skeleton
Book lungs
Mix of gills and lungs used to breath
Regeneration
Growing new body parts from broken or lost ones
Madreporit / sieve plate
Water enters vascular system
Ring canal
Surrounds mouth and leads to the radial canals
Radial canals
5 total - one on each arm
Ampulla
Muscular sac that controls the tube feet by forcing water into it
Tube feet
Create suction to adhere to surfaces
Chordatas animals
Mammals birds fish amphibians
Notochord
Spinal chord or nerve card
Ectothermic
Endothermic
Cold blooded
Warm blooded
Swim bladder
Helps with buoncancy
Bony fish
Skeleton made of bones
Trout and tuna as example
Cartilaginous fish
Skeleton made of flexible cartilage
Sharks
Jawless fish
Eel like fish no jaw , like a sucker mouth
Gills
Respiration by absorbing oxygen and passing it to the blood stream
Scales
Outside skin for fish
Spawning
External fertilization
Gametes release in water
Fry
Young fish
Usually on their own
Arteries
Carry oxygen rich blood to body
Veins
Carry oxygen poor blood to the heart
Ventricle
Pump blood to body
Atria
Receives blood into heart is singular
Amniotic eggs
Contain yoked to nourish, developing young
Gizzard
Grinds food
Crop
Storage sac for food
Down feathers
Soft fluffy feathers that lie next to the birds body keeps warm
Contour feathers
Stiff
Monogamous
Birds that mate for life
Polygamous
Have several mates
Nests
Most birds build for eggs
Brooding
Sit on eggs to keep warm
Monotremes
Primitive egg, laying mammal
Marsupials
Young are born in an extremely immature state and raised in a pouch
Placental mammals
Fetus carried, and the mom’s uterus were nourished by a placenta until the birth of fully developed offspring occurs
