4. What is one threat to this fish's survival?
1. Latimeria
2. South Africa, catch of Captain Hendrik Goosen and discovered by Marjorie Courtenay-Latimer
3. Previously thought to be extinct at the end of the Cretaceous and was 'rediscovered' without having evolved that much (living fossil).
4. Deep-sea fishing (trawling), which can accidently catch Coelacanths.
