17This term refers to fish whose swimming style involves bending in more than half a sinusodial wavelenghth.
- AAnguilliform
- BCarangiform
- CLabriform
- DRajiform
18This term refers to fish whose swimming method involves undulations mostly limited to the caudal region:
- ACarangiform
- BAnguilliform
- COstraciiform
- DAmiiform
19This term refers to fish whose swimming method involves undulation limited to caudal fin due to an inflexible body.
- AOstraciiform
- BLabriform
- CCarangiform
- DBalistiform
20This term refers to fish whose swimming method uses the pectoral fins for most of the force of locomotion, and very little use of the caudal fin.
- ALabriform

- COstraciiform
- DRajiform
21[blank_start]Rajiform[blank_end]: sine waves passed along elongated pectoral fins

23[blank_start]Viscous[blank_end] drag (frictional) [blank_start]is relatively constant[blank_end] over range of speed and is sensitive to [blank_start]surface area[blank_end].
[blank_start]Inertial[blank_end] drag (pressure differences as result of water displacement) [blank_start]increases[blank_end] as speed increases and is sensitive to [blank_start]body shape[blank_end].- AViscous
- BInertial
- CInertial
- DViscous
- Eis relatively constant
- Fincreases
- Gincreases
- His relatively constant
- Isurface area
- Jbody shape
- Kbody shape
- Lsurface area
24Thin bodies induce [blank_start]viscous[blank_end] drag because of the [blank_start]large[blank_end] surface area relative to muscle mass, but thick bodies induce [blank_start]inertial[blank_end] drag due to the [blank_start]large[blank_end] cross-sectional area of the body.
Scaleless skin has [blank_start]low[blank_end] viscous drag. Streamlined shapes produces [blank_start]minimal[blank_end] inertial drag.- Aviscous
- Binertial
- Clarge
- Dsmall
- Einertial
- Fviscous
- Glarge
- Hsmall
- Ilow
- Jhigh
- Kminimal
- Lmaximal

28Assemblages of vertebrates on coral reefs have low diversity.
- AVerdadero
- BFalso
29Why are many fish who live beneath the euphotic zone bright red?
- AThe bright color warns predators that they are toxic.
- BThe brighter the color, the more likely they are to achieve a mate.
- CBecause red light does not extend past the euphotic zone, so the fish can blend in with their surroundings.
- DBecause they're drama queens.
