Evidence of a Potential Nursery Area for the Great Hammerhead Shark, <i>Sphyrna mokarran</i>, in the Largest Coral Reef System of the Southwestern Atlantic. [PDF]

Ecol Evol
We present evidence suggesting that the Abrolhos Bank functions as key habitat for early life stages of Sphyrna mokarran. Kernel density estimation revealed spatially structured aggregations, with neonates and young‐of‐the‐year concentrated in shallow reef‐associated areas. Temporal variation in catch per unit effort (CPUE) indicated recruitment pulses
