Plankton
|
All organisms that drift with the current.
|
|
|
Phytoplankton
|
plants that follow a drifting lifestyle in the upper layers of the water.
|
|
|
Zooplankton
|
much like phytoplankton, however, these are animals.
Ex. Copepods |
|
|
Cyanobacteria
|
(blue green algae)- most primitive type of plant-like organisms, and are microscopic.
|
|
|
Diatoms
|
(single cell, asexual reproduction)a frustule (cell wall) that is most commonly made of silica.
|
|
|
Dinoflagellates
|
(single cell, photosynthetic) Some photosynthetic, some not. Most use a pair of flagella for locomotion. Responsible for red tides, common in the fall.
|
|
|
Phylum Protista
|
marine
shelled amoeba Two types: Foraminifera- CaCarb Shell Radiolara- silica shell |
|
|
Phylum Proifera
|
sponges
marine green/orange/red |
|
|
Phylum Cnidaria
|
Stinging tentacles, posses a true gut (like animals), but there is only one opening (mouth is anus).
|
|
|
Types of Cnidaria
|
sea anemones, jelly fish, coral
radial symmetry one opening (anus is mouth) |
|
|
Phylum Ctenophora
|
comb jellys
more advanced than jellys difference: lack nematocysts (8 bands of cilia on outside to move with) |
|
|
Phylum Annedlida
|
Segmented worms.
|
|
|
Polychates
|
Annedlida- marine worms with jaws, tentacles, and lateral extensions of the body (provide for locomotion) (clam worm)
|
|
|
Oligochaetes
|
Annedlida- cylindrical shaped worms that burrow in soils or live in shallow waters. (earthworm)
|
|
|
Hirudinea
|
Annedlida- leeches. have 2 suckers.
|
|
|
Phylum Anthropoda
|
Has hard exoskeleton made of chitin that supports and protects against desiccation. Also have joined appendages that raise the body off the ground.
Ex. Blue Crab, Crayfish, Horseshoe Crab |
|
|
Phylum Mollusca
|
Interior head, ventral foot, dorsal mass, shell, radula. Soft bodied animals that found mainly in marine habitats.
|
|
|
Amphinerura
|
Phylum Mollusca-
Chitons Live on rocks on by the seashore. Radula large ventral foot shell is in 8 sections. |
|
|
Gastropoda
|
Phylum Mollusca-
Snails "stomach foot" largest group have prominent head with ventral foot. Shell Spirals Nudibranchs=marine; slugs and nudibranchs are like snails without shells |
|
|
Pelecypoda
|
Phylum Mollusca-
Hard Shell Clams, Razor Clams, Oysters bivalve (2 Shells) reduced or lack of head, prominent mantle, often have a foot for burrowing in the sediment and often move water over their gills. (incurrent and excurrent) |
|
|
Cephalopoda
|
Phylum Mollusca- squid, octopi, nautili. Mantle covers their body. Nautili secrete shells over their body but in squids and octopi the shell is reduced to a "pen", which is sunk into the body. Funnel and tentacles act like a goot.
|
|
|
Scaphopoda
|
Phylum Mollusca- Tooth and tusk shells, live in mud, typically west coast. Inidians used them for currency.
|
|
|
Phylum Echinodermata
|
Spiny skinned
radially symetrical= adults bilaterally symetrical= larva no head no segmentation 5 part body or multiples of 5 thin erpidermis epidermis covers endoskeleton has a spine water vascular tube- food |
|
|
Asteroidea
|
Phylum Echinodermata
star fish carnivores tube feet- pressure on prey ventral mouth large central disk stout arms |
|
|
Ophiuroidea
|
Phylum Echinodermata
brittle stars small central disk arms more dependant than cent. disc tube feet gather food |
|
|
Echinoidea
|
Phylum eCHINodermata
sea urCHINs tube feet (movement) |
|
|
Holothuroidea
|
Phylum Echinodermata
Sea cucumbers burrow in sediment/eat it detritivores (earthworm) skeleton reduced small spicules in leathery epidermis |
