Flipping through the journal, you see that this explorer discovered an uncharted island in the South Pacific in the late 1800s and made sketches and notes of the wildlife he found there. It is obvious that no other visitor has since been on this island because all of the species he describes are unlike anything you have ever seen. Although this explorer was an excellent captain and adventurer, he apparently was a terrible biologist. He found many species of fish whose bodies were long and narrow, and since they looked superficially similar, he assumed they were all related to one another. However, you know that there are many other characteristics that set groups of fish apart besides the shape of their bodies. The following image shows the sketches and notes from one page of the explorer's journal, describing one of these fish species. This fish is a vile creature, first found buried in the freshwater riverbed. Possessing no eyes, it is still able to sense prey with its long tentacles and erupts from its hiding place to entangle it. Having no backbone, it is most flexible, and it is able to knot itself around its prey. It does not consume the prey right away, as it has no jaws to engulf or chew; rather, it covers the prey in a strange cocoon of thick slime, paralyzing it until it dies. The creature then feeds on Cartilaginous skull Nerve cord the decomposing carcass. Notochord Gills

**Description and Sketch of the Discovered Fish Species**
*This fish is a vile creature, first found buried in the freshwater riverbed. Possessing no eyes, it is still able to sense prey with its long tentacles and erupts from its hiding place to entangle it. Having no backbone, it is most flexible, and it is able to knot itself around its prey. It does not consume the prey right away, as it has no jaws to engulf or chew; rather, it covers the prey in a strange cocoon of thick slime, paralyzing it until it dies. The creature then feeds on the decomposing carcass.*
**Detailed Sketches and Annotations:**
1. **Cartilaginous Skull:** The drawing highlights the fish’s skull, indicating it is made of cartilage rather than bone.
2. **Nerve Cord:** A vital structure noted in the sketch, showing the main nerve cord running along the body.
3. **Notochord:** Annotated as part of the central support structure in the fish.
4. **Gills:** Indicated near the head, these are the respiratory structures allowing the fish to extract oxygen from water.
The sketches provide a visual representation and anatomical insight into this unique and eerie species discovered by the explorer.
