• Your topic: Nudibranchs

• What do you already know about this topic?

1. The only thing I knew about nudibranchs was that they were a type of sea slug. I

knew this only because it was in a magazine cover in my dentist’s office.

• What questions do you have about this topic? What do you want to know (specifically)?

1. Where do nudibrnachs thrive? How do such small, squishy creatures withstand

the harsh pressure of the ocean? What do they eat, and what eats them?

• Keyword you are using to search for article on this topic:

1. Nudibranchs, diet, predator, location

• Article source and URL:http://www.dive-the-world.com/creatures-nudibranch...

• Predict what this article will be about (what questions will it answer for you?):

1. I predict that this article will lead me to a general introduction of nudibranchs. It

is unlikely to contain any in-depth discussion of their evolutionary biology, much

less where nudibranchs are placed within a given genetic tree.

2. If there is an article about them, I assume that the article will yield either a “This

is cool, look at this” response with general facts. Or it will explain the importance

of scientific research being performed on nudibranchs.

• While reading the article, use the space below to take notes on key facts and define

unknown words.

1. Known for large variety of intense coloration

2. Belong to Family Nudibranchia, Order Mollusca.

3. Rhinophores: tentacles on nubibranch heads that can smell, taste, and touch

4. They can weigh up to 1.5 kg. A 1.5 kg sea slug. This article has replaced spiders,

exams, and scary movies with a new nightmare.

5. When nudibranchs are not eating, they are inactive. This lasts around 5 hours per

day.

6. Nudibranchs are carnivores, not filter-feeders, which I had thought would be the

case.

1. They eat sponges, anemones, other slugs, their own eggs, and other

unlikely things

2. Eating is facilitated via “radula” in their “mouth” that is coated with hard,

shrapnel-like teeth that grind.

3. Most amazing of all: some nudibranchs are solar powered, and use the

algae growing in their outer tissues as a source of sugar via

photosynthesis.

4. Predators: Other nudibranchs, turtles, crabs

• Summarize the main ideas of the article in your own words:

1. Nudibranchs are an ocean-dwelling species of gastropod. They have a few

interesting features, such as their color and the aforementioned sugar catalysis via

algae, and if you really consider how large a 1.5 kg slug is, you will support

scientific research because we need to know our enemy before they strike.

• What new facts did you learn?

1. How they eat

2. What they eat

3. Size

4. Location
