Sharks Eat Seagrass, Remind Us of Pre-Fall World
National Geographic has an intriguing article on the eating habits of bonnethead sharks (Sphyrna tiburo).
Researchers put seagrass as bait and noticed that the sharks ate it. There’s no doubt about it, as they filmed the unexpected episode.
The researchers found out that over 50 per cent of the sharks’ diet consisted of seagrass. They were able to digest 56 percent of the organic matter in seagrass.
Previous reminders of Eden have included a lioness that herds sheep instead of eating them, a cat that adopted ducklings and a vegetarian spider.
These things should hardly happen in a Darwinian world where nature is supposed to be red in tooth and claw.
Sharks are living fossils that haven’t changed in “400 million years.”
