Marine Mammal Biology
Specialized glands that produce milk.
Mammary glands
Primary purpose of blubber besides insulation.
Energy storage (not accepting anything else)
Plant-eating marine mammal order.
Sirenia
The underwater habitat dominated by large brown algae.
Kelp forest
The only marine mammal order composed entirely of herbivores.
Sirenia
Body temperature regulation through internal heat production.
Endothermy/ (I'll accept endothermic but not warm-blooded)
The primary function of pectoral flippers during swimming.
Steering
The taxonomic level directly above species (since yall struggle with this)
Genus
The accidental capture of marine mammals in fishing gear.
Bycatch
Marine mammal most vulnerable to boat strikes.
Manatee
The biological process that maintains a stable internal temperature.
Homeostasis (anything else is wrong)
The horizontal orientation of whale flukes is best suited for this movement.
Vertical swimming (not accepting anything else, if you just put swimming that's too bad)
The broadest taxonomic group shared by whales and sea otters.
Animalia
The long-lasting pollutant that can accumulate in marine mammal tissues over time
Heavy metals (I'll accept Mercy and Cadmium as it's the main two)
The marine mammal whose closest living relative is the elephant.
Dugong
The slowed heart rate during dives.
Bradycardia
The adaptation that allows seals to locate prey in dark water by touch
Sensitive whiskers
Evolution occurring when populations become increasingly different over time.
Divergent evolution
The loss of genetic diversity caused by extremely small populations.
Bottleneck effect
Largest toothed predator.
Sperm whale
The life stage when many marine mammals possess their greatest amount of body hair.
Fetal stage
Marine mammals generally exhale before diving to reduce problems caused by changing ______.
Pressure (The problems are caused by a change in what)
The biological process by which new species arise.
Speciation
The ocean zone receiving enough sunlight for photosynthesis.
Epipelagic zone (Not accpeting anything else)
The marine mammal family that includes narwhals and belugas.
Monodontidae
