+
+This endpoint defines a GET route at `/lions` that retrieves all sea lion instances from the database using SQLAlchemy's `db.query(SeaLion).all()` method. The `response_model` parameter is set to `List[SeaLionSchema]`, assuming that a `SeaLionSchema` Pydantic model exists to define the response structure.
+
+The main entity this endpoint works with is `SeaLion`. Note that you'll need to import the `SeaLion` model and `SeaLionSchema` from their respective modules.
