- Have students express the ideas of the text (the predatory and mating habits of the anglerfish) in their own words. Re-write the text, draw a diagram or series of illustrative/cartoon panels, create an animated video, etc.
- (California Reading Standards for Literacy in Science and Technical Subjects 6–12, standard 2: Determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions.)
- Familiarize students with the concept of anthropomorphism. Explain that anthropomorphism is the practice of attributing human characteristics to anything that is not a human being—plants, forces of nature, or, in this case, fish. Explain that anthropomorphism is not based on “reasoned judgment.”
- Have students identify words that may anthropomorphize the physical or behavioral characteristics of the anglerfish. Review how this language is suggestive or leading.
- Discuss how students would present the same information using less anthropomorphic language.
- (California Reading Standards for Literacy in Science and Technical Subjects 6–12, standard 8: Distinguish among facts, reasoned judgment based on research findings, and speculation in a text.)
- Although some female anglerfish can grow up to a meter (3 feet) in length, this one is only about 8 centimeters (3 inches). The male is less than a centimeter (about a quarter inch) in length.
- Some male anglerfish have a stunted or incomplete digestive system. They have to find and attach themselves to females or die of starvation.
- Like most fish, female anglerfish lay hundreds of (unfertilized) eggs at a time. One species of anglerfish (the monkfish) ejects a slimy sheet of material that holds the eggs. The sheet can be about a meter (3 feet) wide and 10 meters (33 feet) long. (Most fish have to rely on a passing male fish to fertilize the waterborne eggs. The female anglerfish, of course, can do it herself with the male organs attached to her body.)
- The esca—the fleshy filament protruding from the female anglerfish’s head—is actually part of her spine.
- There are more than 200 species of anglerfish.
