1

Fungi

decomposers
‘Saprophytes’

2

Phylum porifera
-spicules -->
-spongin -->

-hard structure either CaC3 or SiO2
-glycoprotein complex

3

Class anthozoa

-Sea anemones and corals
-Most corals require clear, warm, h20
-Less suspended stuff

4

Flatworms

Eye spots
-exhibit negative phototaxis. Move away from light
-Regenerate lost parts

5

aposomatic coloration

look at meh (nudibranchs)
--> warning coloration
Subclass Opisthobranchia

6

Opposite of semalparity

is iteroparity – more than one reproductive event (class cephalopoda)

7

competition

conflict that may arise when resources become limiting
Compete for food/nutrients, mates, space

8

sexual dimorphism

Diff in app based on gender

9

cavitation

- shock wave from air bubble production. order stomatopoda

10

breaching in whales

whale leaps out of water exposing majority of body above surface

11

coloration

the shallower an oceanic organism is, is more transparent

12

pen

squids have internal shell called pen

13

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 *

14

how many species of fish?

33,000

15

Ampullae of Lorenzini

Spiracles – ancestral --> H20 intake

16

scutes

light reflectors

17

sexual parasitism

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.

18

stumpknocking

group of males shows off and knocks, female picks the best fitted

19

cross dressers

female mimics. Color change

20

Why d0 amphibians have no present day marine representatives?

lack of adaptation of kidney cause no osmotic balance

21

Endemism

-origins at a specific site/place

22

natant beach

beach of their birth

23

what is a marine organism?

Aquatic (osmotic balance), 51% or more of nutrients come from marine environment, and adaptation for aquatic life

24

pelagic birds
Keel

skeletal structure for muscular attachment

25

where are penguins found?

Southern hemisphere

26

Ontogeny

recapitulates phylogeny (haeckel)

27

Whales- Rorqual

pleated throat

28

gular pouch

pelicans use this as net to catch fish

29

Ovoviviparity

in sharks embryos develop inside eggs and are retained in mother's body until they are ready to hatch

30

salt gland

organ for excreting excess salts. found in elasmobranchs and some reptiles.
