Tolerant of only small changes externally
2
Q
Euryhaline
A
Can osmoregulate over a wide range of environmental salinities
3
Q
Ectothermic
A
Cold blooded animal, temperature relies on external factors
4
Q
Endothermic
A
Warm blooded animal, temperature relies on internal sources of regulation.
5
Q
Gills and counter currents
A
Blood flows in the opposite direction to water flow ensures a constant diffusion gradient.
