+
+This code defines three Pydantic models for the SeaLion entity:
+
+1. `SeaLionBase`: A base model that defines the common fields for the entity.
+2. `SeaLionCreate`: A model that inherits from `SeaLionBase` and is used for creating new sea lion instances.
+3. `SeaLion`: A model that inherits from `SeaLionBase` and includes an `id` field, which is used for representing sea lion instances in API responses.
+
+Each model includes field descriptions and example values in the `Config` class. The `SeaLion` model also includes an example value for the `id` field.
