The narrator is exploring an underwater environment, specifically the Salish Sea and its islands, in search of marine life. They are particularly interested in the marine life that inhabits the intertidal zone, which is exposed at low tide. The narrator discusses the unique and fascinating species they encounter, such as the sea lemon (also known as a droid), a rock prickleback, and a chitin mollusk known as a gumboot.
The sea lemon is a small creature related to slugs and mollusks. It has distinct sensory organs that help it sense chemicals in the environment. The rock prickleback is the largest species of chitin in the area. It is also a mollusk related to slugs and snails. The gumboot chitin is a large species that is primarily herbivorous, feeding on algae. It has a unique rugged skin called the girdle that helps protect it against potential predators.
The narrator is also interested in the unique characteristics of these species. For example, the sea lemon has very distinct little black speck links all over its back. The rock prickleback can grow to be about three feet in length and has a dorsal spine that helps it balance when swimming. The gumboot chitin has a tough skin and can curl up to protect its foot, mouth, and gills.
Despite the beauty and fascination of these creatures, the narrator reminds the audience to respect the marine environment and the creatures that inhabit it. They also mention that the gumboot chitin is edible by humans, though this is not something they would recommend due to its chewy texture.
In conclusion, the narrator's exploration of the intertidal zone reveals a rich and diverse marine ecosystem. They highlight the importance of preserving and understanding this ecosystem for future generations.
