Where do harp seals live?
- A.
Warm waters
- B.
Cold waters
- C.
Rivers
- D.
Ponds
Correct Answer
B. Cold watersExplanation
Harp seals live in cold waters because they are adapted to survive in Arctic and sub-Arctic regions. These seals have a thick layer of blubber and a dense, waterproof fur that helps them stay warm in freezing temperatures. They are also excellent swimmers and can dive to great depths to find food. Cold waters provide the ideal habitat for harp seals to thrive and find an abundance of fish and other marine prey.Rate this question:

- A.
Europeans
- B.
Nobody is allowed to hunt them
- C.
Asians
- D.
Eskimos
Correct Answer
D. EskimosExplanation
Eskimos are allowed to hunt Narwhals. This is because Eskimos have traditionally relied on hunting Narwhals for their survival and have a deep cultural connection to the practice.

What are Walrus' tusks made of?
Correct Answer
ivoryExplanation
Walrus' tusks are made of ivory. Ivory is a hard, white material that comes from the tusks and teeth of animals, such as elephants, walruses, and narwhals. It is composed mainly of dentin, a calcified tissue, and is highly valued for its durability and aesthetic appeal. Walrus tusks are particularly prized for their size and quality, with some reaching lengths of up to three feet. Ivory has been historically used for various purposes, including carving, jewelry, and as a material for piano keys. However, due to concerns over animal conservation and illegal trade, the use and sale of ivory are now heavily regulated.Rate this question:

The Beluga whale does not have a(n)
- A.
Dorsal fin
- B.
Anal fin
- C.
Caudal fin
- D.
Pectoral fin
Correct Answer
A. Dorsal finExplanation
The Beluga whale does not have a dorsal fin. The dorsal fin is a fin located on the back of a fish or marine mammal, used for stability and balance in the water. While most whales have a dorsal fin, the Beluga whale is an exception. Instead, it has a small hump on its back that is not considered a true dorsal fin. This adaptation allows the Beluga whale to swim easily under ice and in shallow waters, where a dorsal fin could be a hindrance.Rate this question:
-
- 8.
What color are Beluga Whales?
Correct Answer
whiteExplanation
Beluga whales are known for their distinctive white color. This coloration is due to the thick layer of blubber beneath their skin, which helps to insulate them in their cold Arctic habitat. The white color also provides camouflage in their icy surroundings, making it easier for them to blend in and avoid predators. Additionally, their white coloration may help them communicate with other members of their pod, as they can easily spot each other in the water.Rate this question:
- 9.
Where do Fin whales go to mate?
- A.
Greenland
- B.
Red Sea
- C.
Arctic waters
- D.
Subtropic waters
Correct Answer
D. Subtropic watersExplanation
Fin whales, the second largest species of whales, are known to migrate to subtropic waters to mate. These waters provide favorable conditions for breeding, such as warm temperatures and abundant food sources. Mating in subtropic waters allows fin whales to ensure the survival and successful reproduction of their species. Additionally, these waters may offer protection from predators and provide suitable environments for courtship rituals. Therefore, fin whales choose subtropic waters as their preferred location for mating.Rate this question:
-
- 10.
How many tons of food can a Fin whale consume in a day?
Correct Answer
2 tons
2
twoExplanation
A Fin whale can consume up to 2 tons of food in a day. This massive amount of food intake is necessary to sustain their large size and energy requirements. With their baleen plates, they filter feed on small fish and krill, consuming vast quantities to meet their nutritional needs.Rate this question:

Baby ribbon seals have what which provides them with insulation until they fully mature?
- A.
Blubber
- B.
Lanugo
- C.
Hair (grey)
- D.
Spikes
Correct Answer
B. LanugoExplanation
Baby ribbon seals have lanugo which provides them with insulation until they fully mature. Lanugo is a fine, soft hair that covers the body of newborn seals. It helps to keep them warm by trapping a layer of air close to their skin, acting as insulation. As the seals grow and develop more blubber, the lanugo eventually falls off.Rate this question:

What is the Manatees' closest relative?
- A.
Dolphins
- B.
Dugongs
- C.
Elephants
- D.
Cows
Correct Answer
B. DugongsExplanation
Dugongs are the closest relatives of manatees. Dugongs and manatees belong to the same order called Sirenia. They share similar physical characteristics and both are herbivorous marine mammals. They have a similar body shape, with a large round body and paddle-like flippers. Both species also have a similar diet, feeding on seagrass and other aquatic vegetation. Due to these similarities and their evolutionary history, dugongs are considered the closest relatives of manatees.Rate this question:

What is the leading cause of death for Manatees?
Correct Answer
boats
boatExplanation
The leading cause of death for Manatees is boats. Manatees are often struck by boats, which can result in fatal injuries. The collision with boats can cause severe trauma, leading to death or serious harm to these marine mammals. Therefore, the presence of boats poses a significant threat to the survival of Manatees.Rate this question:

Spotted Dolphins...
- A.
Are born with spots
- B.
Go through different color stages
- C.
are black and white
- D.
Aren’t spotted at all
Correct Answer
B. Go through different color stagesExplanation
Spotted Dolphins go through different color stages. This means that they are not born with spots, but rather develop them as they grow.

- 24.
What is the main threat of spotted dolphins?
Correct Answer
fishing netsExplanation
Spotted dolphins face a significant threat from fishing nets. These dolphins often get entangled in fishing nets while swimming, which can lead to injury or even death. The nets restrict their movement and ability to find food, making it a major threat to their survival. Conservation efforts are necessary to reduce the impact of fishing nets on the population of spotted dolphins and ensure their long-term survival.Rate this question:

What animal is the main predator of Sea Otters?
Correct Answer
orca
killer whale
orcas
killer whalesExplanation
The main predator of Sea Otters is the orca, also known as the killer whale. Orcas are known to prey on Sea Otters, as well as other marine mammals. They are highly intelligent and skilled hunters, capable of taking down larger prey. Sea Otters are particularly vulnerable to orca predation due to their smaller size and slower swimming speed. Orcas often work together in groups to hunt and can easily overpower and kill Sea Otters.Rate this question:

Sea Lions generally...
- A.
Live in packs
- B.
Live alone
- C.
Live as a pair
- D.
Live as a small family... mom, dad, babies
Correct Answer
A. Live in packsExplanation
Sea Lions generally live in packs because they are highly social animals that prefer to live and hunt together in large groups called colonies or rookeries. Living in packs provides them with protection against predators, helps in finding food, and allows for social interaction and communication. These groups can consist of hundreds or even thousands of individuals, and they establish a hierarchical structure with dominant males leading the pack. Living in packs also facilitates breeding and raising their young as they can collectively defend and care for the offspring.Rate this question:
