Quiz Answer Key and Fun Facts

1. This small crustacean is named for the colour of its carapace. It lives on the Pacific shores of North America, grows to about 2 inches in length, and lives on algae and dead animals.

Answer: Purple shore crab

This crab has a dark purple shell and white underbelly, as well as reddish and purple spots on its claws. The European green crab is a predator who preys on oysters and young Dungeness crabs. The
blood shrimp is found in the Indian ocean, and the lemon lobster is a tasty way of cooking lobster.

2. This fish has an unusual defence mechanism. When it feels threatened it fills its body with water so it becomes too big for a predator to swallow. It is also covered with sharp spines.

Answer: Porcupine fish

The other three fish are predators who use camouflage to hide from unsuspecting small fish.

3. This worm has feathered bristles along its sides that can deliver painful stings. It lives under rocks and can reach six inches in length.

Answer: Orange fireworm

The other three worms are tubeworms who prefer to retreat when they feel threatened.

4. This sponge is very common in the Pacific ocean. It grows in colonies and is named for its striking colour.

Answer: Yellow Sponge

Sponges are among the oldest and most primitive animals on earth. Although most of them grow in colonies that are home to much other sea life, some sponges are carnivorous and dine on small crustaceans. Red tree sponges and purple tube sponges are found in the Caribbean. Spongebob Squarepants is found on your TV if you have small children.

5. This symbiotic creature removes parasites and dead scale from fish.

Answer: Cleaner shrimp

Some people get them for their aquariums; they are a great natural cure for Ich.

6. This lobster digs through the sand to find its food.

Answer: Slipper Lobster

The slipper or shovel lobster has hard plates instead of antennae to help it dig. It takes a lobster about seven years to grow to one pound. They can live for over fifty years.

7. This is the largest of the sea turtles:

Answer: Leatherback Sea Turtle

The leatherback sea turtle grows to six feet in length, about twice as much as the other three who range from 24 to 43 inches. Its shell has no scales but is covered with a rubbery leatherlike skin.

8. Sharks are generally dangerous to humans.

Answer: False

Of the hundreds of shark species, only a few have been known to attack humans, and even then it is thought to be mostly a case of mistaken identity: a diver in a dark wet suit may look like a seal to a shark, who generally attacks from below.

9. Which of these statements about octopuses is false?

Answer: Octopuses have poor eyesight

Octopuses' visual acuity is comparable to humans. Their eyes are highly complex and able to focus by moving the lens in and out. The blue-ringed octopus has a defensive poison that can kill a human. Octopuses can survive out of water for a while if kept cool and damp, and they have been known to eat their own arms when stressed.

10. Which of these is a common theory, probably apocryphal, about how the right whale got its name?

Answer: It was considered to be the best whale to hunt

Its body is extremely rich in oil. Today there are fewer than 350 left alive, making it the most endangered of all whales.
