In the 1970s, Nigel discovered a treasure trove of sharks and rays that were using the Casamance estuary in Senegal as a nursery ground. He also found an abundance of sawfishes. More than 40 years on and every indication is that the sawfishes in the region are all but extinct. Nigel is going back to find out if those indicators are right.
This 4.5-metres largetooth sawfish was caught in October 1975 and reconstructed for the photograph. The sawfishes were a nuisance for local fishermen because they became entangled in their nets and damaged them. Photo by Nigel Downing
