 * **zoomToBoundsOnClick**: When you click a cluster we zoom to its bounds.
 * **spiderfyOnMaxZoom**: When you click a cluster at the bottom zoom level we spiderfy it so you can see all of its markers. (*Note: the spiderfy occurs at the current zoom level if all items within the cluster are physically located at the same latitude and longitude.*)
 * **removeOutsideVisibleBounds**: Clusters and markers too far from the viewport are removed from the map for performance.
+* **spiderLegPolylineOptions**: Allows you to specify [PolylineOptions](http://leafletjs.com/reference.html#polyline-options) to style spider legs. By default, they are `{ weight: 1.5, color: '#222' }`.
 
 You can disable any of these as you want in the options when you create the MarkerClusterGroup:
