The Sunlight Zone is called this because it gets more of what type of energy than any other zone?
Sunlight.
100
True or false: this zone receives no sunlight at all and is completely dark even in the daytime.
False. The Twilight Zone receives a little bit of sunlight, which makes it pretty dark during the day, but not completely.
100
True or false: this zone only gets sunlight for 5 minutes every day.
False. No sunlight can penetrate down into the Midnight Zone, which reaches from 1,000 meters (about 3,000 feet) to 4,000 meters (about 13,000 feet) down.
100
True or false: Abyssal zone giant tube worms can grow to be taller than Matt.
True. They can grow to be over seven (7) feet tall. Matt is only 5'10".
100
True or false: most of the ocean that lies in this zone, is found in underwater canyons and trenches?
True. Most of the ocean floor is in the Abyssal zone; the trench zone is found in deeper "holes" in the ocean floor between 6,000 meters (about 20,000 feet) and the lowest part of the entire earth, the Mariana Trench off the coast of Japan, which is 11,000 meters (about 36,000 feet) below the surface of the ocean.
200
What type of living thing can be found in the Sunlight Zone and in no other zone?
Plants.
200
What animal that can change it colors to hypnotize other fish lives in the Twilight Zone? (Hint: it is Matt's favorite animal.)
The totally, completely, absolutely amazing CUTTLEFISH! Of course.
200
The only light to be found in this zone comes from: A) The sun B) The moon C) Animals D) Plants
C) Animals. Some animals, such as anglerfish, have bacteria in their bodies which glow. This is called "bioluminescence" which means "living light".
200
True or false: Colossal squid grow to be over 100 feet long.
False. Colossal squid are very big, but the largest one ever seen was forty-six (46) feet long. It weighed 1,600 pounds which is almost a ton; Matt weighs about 1/10 of that (160 pounds).
200
The deepest living fish ever recorded on film was a: A) Snailfish B) Hammerhead shark C) Blue whale D) Giant squid
A) snailfish. A Hadal snailfish was recorded on film at more than 8,000 meters down.
300
Does the Sunlight Zone contain: A) One quarter (1/4) of all marine life B) Half (1/2) of all marine life C) More than 9/10 of all marine life?
C) More than 9/10 of all marine life.
300
True or false: only a few species of plants can live in the Twilight Zone?
False, no plants can live here.
300
True or false: the vampire squid got its name because, unlike other squid which eat fish, it only drinks the blood of its prey.
False. The vampire squid got its name because it looks scary. But it doesn't hunt for food at all; it eats the marine snow that drifts down from higher in the ocean. This isn't very tasty, but it means that the vampire squid doesn't even have to move to find food; it just floats and waits.
300
True or false: dumbo octopi are usually tiny, but scientists have seen one that was the size of Matt.
True. They are usually quite small, about the size of Matt's thumb, but ocean scientists have found one the size of Matt.
300
Sea anemones in the Trench zone shoot what to capture prey: A) lasers B) Blue whales C) tiny, poisoned harpoons D) a cloud of acid
C) tiny, poisoned harpoons. This poison can sting humans, but paralyzes small animals. The anemone then pulls the harpoon back, dragging the paralyzed animal with it so that the anemone can eat it.
400
Blue, humpbacked, and sperm are three species of this animal which can usually be found in the Sunlight Zone?
Whales.
400
True or false: plants cannot live in this zone because it is too cold for them.
False: plants can survive very cold temperatures; a few species grow in Antarctica! But they need sunlight to live and there isn't enough in the Twilight Zone.
400
How much of the entire ocean is found in the Midnight Zone? A) A tenth (1/10) B) A quarter (1/4) C) Half (1/2) D) Over 9/10.
D) Over 9/10 of all the water in the ocean is in the Midnight Zone even though most of us think of the whole ocean as the Sunlight Zone.
400
Some deep-sea shrimp in the Abyssal Zone actually eat: A) Rocks B) Water C) Trees D) Colossal squid
C) Trees. Although there are no plants living way down between 4,000 and 6,000 meters (about 13,000 to 20,000 feet), dead plants fall down from above. Leafy plants disintegrate before they make it to the Abyssal zone, but some trees stay together and certain deep-sea shrimp eat them for food.
400
True or false: Supergiant amphipods in the Trench zone grow over 1,000 feet long and look a bit like Godzilla.
False. The supergiant amphipod is much, much bigger than the usual kind (1-2 inches), but it only grows to about twelve (12) inches long. Also, it doesn't look anything like Godzilla, but more like a shrimp or a lobster.
500
True or false: while half of the world's oxygen is produced by plants on land (such as in the Amazon Rainforest), the other half of the world's oxygen is produced by tiny creatures in the Sunlight Zone called "phytoplankton"?
True. Phytoplankton are too small to be seen by the eye, but they grow by photosynthesis just like land plants and are so abundant that they make as much oxygen as the plants on land.
500
Which of these animals does NOT live in the Twilight Zone" A) Crabs B) Swordfish C) Colossal squid D) Wolf eel
C) Colossal squid. These huge animals live down in the Abyssal Zone.
500
For animals living in the Midnight Zone, marine snow is an important for: A) Sledding B) Eating C) Snowball fights D) Keeping the water cool
B) Eating. Marine snow is actually tiny bits of dead animals from the upper zones drifting downwards as it decays. It's kind of gross, but is an important part of the diet for animals in the Midnight Zone.
500
How much of the ocean floor lies within the Abyssal zone? A) one tenth (1/10) B) one quarter (1/4) C) three-quarters (3/4) D) over 9/10
C) three-quarters (3/4) of the ocean floor is in the Abyssal zone. This means that most of the "bottom of the ocean" is in this zone.
500
True or false: sea cucumbers look peaceful, but they will fight any other sea cucumbers that invade their territory.
False. First, how could a sea cucumber fight another sea cucumber? Seriously; they look like cucumbers! Second, sea cucumbers live in large herds on the sea-bottom
