While photographing at Los Islotes, a small islet in the Sea of Cortez, near La Paz, Baja California Sur, Jim recently photographed a bullseye electric ray (Diplbatus ommata). Bullseye electric rays grow to about 10 inches long, and get their name from the conspicuous eyespot on their back.   Like other electric rays, this species has a pair of organs capable of producing electric discharge that it uses to stun or kill its prey. 

"I've been trying to get a shot of one of these rays for years.  Whenever I saw one, I always had a Nikonos V with a 15mm wide angle lens, which is not the best lens to use to get an animal thats only 10 inches long.  But now with my Fuji S2 digital SLR in an Aquatica housing, I can use a variety of lenses that allow me to capture smaller animals.  This ray posed for me at about 60 feet deep on a cobble stone bottom."
