DAT Diversity Taxa Shit Flashcards
eed by filtering water through the sponge wall of flagellated cells called choanocytes
porifera
The flagellum of choanocytes creates a flow of water for…
filter feeding
used in the development and research of antibiotics
porifera
sea sponges belong to what phyla
porifera
include the hydrozoans, jellyfish, sea anemones, and coral
cnideria
how many body forms does Cnidaria have
2
what are the two body forms Cnidaria have
floating, umbrella-shaped body with tentacles called the medusa, and the sessile cylinder-shaped body with rising tentacles called the polyp.
pecialized cells located in the tentacles and body walls of cnidarians.
Cnidoblasts,
The interior of the cnidoblasts are filled with stinging organelles called…
nematocysts.
three types of acoelomate flatworms to know:
planarians, flukes, and tapeworms
free-living flatworms and are carnivores in marine or freshwater bodies of water.
planarians
internal/ external animal parasites that suck tissue fluids and blood
flukes
internal parasites that often live in the digestive tract of vertebrates
tapeworms
are tapeworms considered to be truly segmented
no
do tape worms have a digestive tract
no, they absorb the food around them
otherwise known as roundworms
nematoda
are pseudocoelomate with a complete digestive tract
nemotoda
free-living soil dwellers that help decompose and recycle nutrients.
nematodes
what are nematodes covered in
resilient substance called the cuticle, which helps them resist degradation
are multicellular organisms with specialized organs enclosed in a pseudocoelom
rotifera
ave a complete digestive tract and are filter- feeders
rotifera
this group includes snails, octopus, squids, and bivalves
mollusca
have highly developed nervous systems with complex brains
octopus
what have two- part shells and include organisms like clams and mussels
bivalves
have coelomate bodies, complete digestive tracts, and usually have open circulatory systems with internal cavities called the hemocoel.
mollusks
do mollusks have complete digestive tracts
yes
the largest Molluscan class and includes animals such as slugs and snails
gastropods
characterized by a single shell
gastropoda
this class includes the octopus and squid.
cephalopoda
high O2 demand, giant nerve fibers, and closed circulatory system
cephalopoda
this class includes clams, mussels, scallops, and oysters
bivalva
these are segmented worms which include leeches, earthworms, and polychaete worms.
annelidia
have suckers at both ends for attachment and movement
leeches
predators of small animals and are blood parasites
LEECHES
WHAT divide the coelom into separate compartments. (ANNELIDA)
SEPTA
this groups includes spiders, insects, and crustaceans
arthorpoda
ave jointed appendages which allows them to be successfu
arthropoda
have well-developed nervous systems, specialized body segments, and exoskeletons made of chitin
arthropoda
what are arthropoda exoskeletons made of
chitin
Arthropods have two kinds of life cycles:
nymphs or larvae.
immature arthropods that look like small versions of the adults,
nymphs
are maggots specialized for eating
larvae
hese organisms have three pairs of legs, one pair of antennae, and spiracles
class insecta
are tracheal tubes used for breathing.
spiracles
more of what species than any other class on earth
insect
hese animals have four pairs of legs and “book lungs,” which are respiratory structures that look like sheets of a book
class arachnida
nclude spiders and scorpions
arachnids
do arachnids have antennae
no
egmented bodies and gills with a variable number of appendages.
crustacea
This class includes crabs, shrimps, lobsters, crayfish, and barnacles.
crustacea
how many pairs of antenna do crustacea have
2
this groups includes sea stars, urchins, and sand dollars.
echinodermata
do echinodermata have complete digestive tracts
yes
they have four main features, which sometimes may just be temporary and exist only during embryonic development.
chordata
dorsal, flexible rod
that functions as support.
notocord
orms the basis of the nervous system. In some chordates, the nerve cord becomes the brain and the spinal cord
Dorsal hollow nerve cord
provide channels across the pharynx to the outside body.
Pharyngeal gill slits
two groups of chordates
invertebraes and vertebraes
