- Lyons Ferry State Park is a public recreation area located near the confluence of the Snake and Palouse rivers, seven miles (11 km) northwest of Starbuck, Washington. The state park is on Route 261, abreast of Lake Herbert G. West, a reservoir on the Snake River created with the construction in the 1960s of the Lower Monumental Dam some 17 miles (27 km) downstream. The park offers facilities for boating, fishing, and swimming. The area is managed cooperatively by the Washington State Parks and Recreation Commission and the U.S. Army Corps of Engineers, which operates the Lyons Ferry Marina.
- Actinopterygii (Wikipedia)
Actinopterygii (/ˌæktɪnɒptəˈrɪdʒiaɪ/; from actino- ‘having rays’, and Ancient Greek πτέρυξ (ptérux) ‘wing, fins’), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called lepidotrichia, as opposed to the bulkier, fleshy lobed fins of the sister class Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles).
