Flashcards in For Final Deck (40)
-hard structure either CaC3 or SiO2
-Sea anemones and corals
-Most corals require clear, warm, h20
-Less suspended stuff
-exhibit negative phototaxis. Move away from light
-Regenerate lost parts
look at meh (nudibranchs)
--> warning coloration
Opposite of semalparity
is iteroparity – more than one reproductive event (class cephalopoda)
conflict that may arise when resources become limiting
Compete for food/nutrients, mates, space
Diff in app based on gender
- shock wave from air bubble production. order stomatopoda
breaching in whales
whale leaps out of water exposing majority of body above surface
the shallower an oceanic organism is, is more transparent
squids have internal shell called pen
What is a fish?
1. Poikilothermic except for scumbrids, xiphon types “warm bodied” *
2. acoustico lateralis (lateral line) “distance touch” *
-Ear bone called otoliths
3. swim bladder +/-
4. fins, medial at least *
5. gills, except lung fishes *
6. aquatic-except many spend time on land *
how many species of fish?
Ampullae of Lorenzini
Spiracles – ancestral --> H20 intake
commonly associated w deep sea anglerfish. M is much smaller than F. Males bite/attach themselves to females w jaws. His morphology disappears. In some cases circulatory systems are joined bw the two. He is dependent on her, she provides everything. The male is a sperm producing organ.
group of males shows off and knocks, female picks the best fitted
female mimics. Color change
Why d0 amphibians have no present day marine representatives?
lack of adaptation of kidney cause no osmotic balance
-origins at a specific site/place
beach of their birth
what is a marine organism?
Aquatic (osmotic balance), 51% or more of nutrients come from marine environment, and adaptation for aquatic life
skeletal structure for muscular attachment
where are penguins found?
recapitulates phylogeny (haeckel)
pelicans use this as net to catch fish
in sharks embryos develop inside eggs and are retained in mother's body until they are ready to hatch
