The daily presence of spinner dolphins, Stenella longirostris, inside a 
small reef offshore the Red Sea coast of southern Egypt was monitored 
from January 2004 to January 2006. Observations indicated marked 
seasonal and daily variations in the use of the reef as a resting and 
socializing area by the dolphins, consistent during the two years of 
monitoring. Overall, the mean number of dolphins present in the reef at 
any day was 39.2 (SD = 39.34, range 0–210), with the lowest presence in 
February to April and the highest in June. Similar to other populations 
of this species in other oceans, dolphins entered the reef between 
daybreak and mid-morning, and started exiting during the afternoon 
hours. Although calves were seen in all seasons, a sharp peak was 
observed in June. Monitoring data provided indications relevant to 
governmental management efforts, which were implemented in 2004 to 
ensure that the dolphins could continue using the reef for their resting 
needs while a sustainable, respectful tourist activity is allowed in a 
designated zone of the reef adjacent to the dolphins’ core habitat.
