fish
- The Burramundy, a fish, grows up as a male, but after 2 years or so, it turns into a female to breed. (i think papaya(papua?) trees are the same)
- Most marine fish can survive in a tank filled with human blood (who even tried this?)
- The Nile catfish swim upside down
- A carp might be able to learn to differentiate music (blues from classical)
- The drum fish hears with its air bladder which transmits sound into their ear bone otherwise known as the “Weberian apparatus.”
