chondrichthyes
sharks and rays- 900 species
26
Osteichthyes
herring, salmon, parrot fish- 25,000+ (96% of all fishes, 50% of all vertebrates, 50% marine)
27
buoyancy of bony fish
Most species have a swim bladder- gas filled sac for adjusting buoyancy Absent in most fast moving fish, absent in all hag fish and cartilaginous fishes.
28
Ectotherms
animals that primarily gain heat through the environment
29
Poikotherms
animals whose body temp adjusts depending on the environment
30
Locomotion
Mucous covered scales and streamlined to reduce drag
31
Sun fish (mola mola)
heaviest bony fish | spend most time in the mesopelagic zone but seen near surface
32
Reproduction of bony fish
-produce eggs that are fertilized externally
33
Sequental hermaphrodites
some species are all born one sex, but change to another during their life (nemo)
34
Cryptic coloration
to blend in with surroundings
35
disruptive coloration
stripes, bars or spots that break up the outline of the fish and confuse the predators
36
Herring sound makers
produce fast repetitive ticks (FRT) | generated by passing air from the swim bladder through their anus
37
Squamata
snakes and lizards
38
Chelonia
turtles and tortoises
39
crocodilia
Crocs and Alligators
40
todays reptile species
1% are marine
41
Sea snakes
sub family hydrophiidae can only survive in water air breathing, non aggressive but highly venomous
42
what do sea snakes feed on?
fish and fish eggs
43
Viviparous
give birth to live young in water (sea snakes)
44
Deadliest sea snake
beaked sea snake
45
Sea Kraits
more primitive than sea snakes oviparous- lay eggs on land eat fish/eels venemous
46
Marine iguanas
``` Amblyrhynchus cristatus only found in galapagos islands lay eggs in sand Herbivores- marine algae laterally compressed tail ```
47
Sea turtles
``` 2 families Cheloniidae Dermochlyidae all species endangered lay eggs on land in sand nests mostly tropical and subtropical ```
48
Dermochlyidae
leatherback turtles
49
turtle shells
each species has a different number of plates | formed from a deeper layer in the dermis than scales on sakes
50
Sea turtle reproduction
no parental care of hatchlings | 100 eggs that incubate for 2 months
51
Sea turtle hatchlings
entire nest emerges at night and head towards the brightest light most die before reaching the ocean (1/100)
52
Leatherback turtles
Largest sea turtle lack scutes and have rubbery skin that allow them to dive deep ENDOTHERMIC
53
Seabird nesting habitats
islands tundras coastal cliffs
54
Seabird reproduction
``` k selected reproduce every 1-3 years produce on land few eggs, big babies lots of parental care ```
55
seabird feeding
different bill shapes enable different feeding methods
56
Birds that can't fly
Penguin
57
oxygen storage in birds while diving
lungs+muscle+blood
58
Penguins
all live in the southern hemisphere except one species | found from tropics to poles
59
Seabird-fishery interactions
killed in bycatch
60
Where do salt water crocs live and how big?
Southeast asia and 7m and 2000+ pounds
61
Foraging in sea birds
different bill shapes for different food
62
Foraging in marine mammals
filter feeding engulfment echolocation strand feeding

66
3 orders of marine mammals (cetecea)
Mystecetes (Baleen whales)- low frequency sounds Odonocetes (toothed whales)- echolocation Sireneia (dugong and manatees)
67
Manatees and dugong (sirenia)
mostly eat sea grass | Closest terrestrial species are elephants
68
seabird
must depend on marine environment for something
69
Monitors
``` Amphibious lizards found in southeast asia laterally flattened tail bigger than iguanas lay eggs in nests on land ```
