17
Q

Galea

A

Have anal fins, most types of sharks

18
Q

Boteida

A

Skates, rays and allied fishes like guitarfish and sawfish

Adapted to benthic habitats(bottom of the ocean)
Durophangous diet (hard shelled pray like snails)
Teeth are flat designed for crushing
Males will develop teeth to immobilize females for copulation suing claspers
Have protrusable mouths (can stretch out and suck)

19
Q

Squalea (modern sharks)

A

Have snouts that overhands the mouth
Tendency for the vertebrae at to become calcified not ossified
The anamel of the teeeth is complex in contruction
Sensory and behavioral characteristics not seen in chaimeras or boatoids
Are larger fish
Mostly marine predators but the biggest one are filter feeders
Chemoreception
Machireception
Larger eyes
(Male) internal fertilization using clasper

20
Q

Chemoreception

A

(Sharks) very large olfactory lobes to the forebrain and are extremely sensitive to things like blood

21
Q

Mechanoreception

A

Neuromast organs that are in the lateral line system are them sentisitive to water pressure

22
Q

Electro reception

A

Integumentary organ called the ampulae of Lorenzini, sensitive to weak electriacal signals emitted by potential pray

23
Q

Oviparity

A

Give birth to livespring while in eggs

24
Q

Ovoviviparity

A

Eggs will incubate and hatch inside the mother body and will be born live

25
Q

Viviparity

A

Young develop inside the mothers placenta and aer born live (spaghetti system)

26
Q

Urea (amonia diffusion?)

A

When proteins are broken down into amino acids for digestion

27
Q

Recta gland

A

The organ that takes in exess of salt in the body and empties out into the posterior part of the intestines, straight to feces

28
Q

Lung fish

A

Lack decided cranium
Have Paletine teeth
Most of their endoskeleton are cartiliginous, except for the cranium
Live in fresh water
Have gills but also use their single lung for when there’s little oxygen (water is stagnant)
Por eyesight, use chemoreception and electro reception
Are oviparous
Aestivate(fish harbonation) in response to dry environments

29
Q

Coelacanths

A

Swim bladder
Ovivivvoprouse
Have ancestral and modern traints( chondraichthyan and osteocthyan trains)
Intercranial joins (allows them to expand their mouth)

30
Q

Sarcopterygian (lobe fish)

A

Lung fish
Coelecanths

31
Q

Actinioterygii

A
32
Q

Holosteans

A

Gars and bowfish

33
Q

Blowfish

A

Cycloid scales
Gulag plate
Swim bladder

34
Q

Teleosts

A

“Complete or perfect” skeleton

Elopomorpha- ells and tarpons
Osteoglassomorpha- bony tongue fishes
Otocephala- hearing link between swim bladder and inner ear
Auteleostophorma- “derived teleosts”

35
Q

Elopepomorpha

A

A group defined by osteological features, not dna evidence
Distinct larva stage
Leptocephalus larvae
95% eel like, other 5% normal fish(tarpons and bone fish)
Catadromous

36
Q

Osteoglossomorpha

A

Bony tounge group
Electric fish group

37
Q

Otocephala

A

Linkage that includes clupeiformes and ostariphysi

38
Q

Clupeoformes

A

Mostly marine fishes
Schooling fish that eat plankton
Weberian apparatus(makes them more aware of surrounding)
Use pheromones for communication
Oviparous

39
Q

Ostasriophysans

A

Cyprinifomrs-minnows, suckers, carps
Gymnotiformes- electric eels
Siluriformes-catfishes
Characiformes- characins

40
