Hammerhead sharks are vanishing from their mountain homes in the Gulf of California, divers say

Hammerhead sharks have seemingly disappeared from two underwater mountains in the southwestern Gulf of California, and fishing is likely to blame, a new study has found. 

Researchers looked at observations from divers over the last 50 years and found that scalloped hammerhead sharks (Sphyrna lewini) experienced a 97% decline at the El Bajo seamount and a 100% decline at the Las Animas seamount — both off the coast of Mexico — between the 1970s and 2010s.
