Notable details
- When hooked, bonefish make blistering runs that can strip 100 yards of backing from a fly reel in seconds.
- Their underslung mouth is perfectly shaped for rooting shrimp, crabs, and worms out of sandy tidal flats.
- The name 'bonefish' refers to their dense network of tiny intramuscular bones, which makes them poor eating despite their prized status.
- Albula glossodonta can grow to about 35 inches long and are commonly found in schools patrolling shallow tropical flats.
- They are so wary that fly anglers must cast several feet ahead of a moving school to avoid spooking it.
