November 13, 2018 - An ocean sunfish (Mola mola) has recently been added to the Open Sea exhibit. A sunfish can dive to depths of 1,800 feet, or it might be seen laying flat on the ocean's surface, sunbathing. Scientists theorize this helps warm up its body after deep dives. The largest species of bony fish in the world, a sunfish can reach a staggering weight of 5,000 pounds and a total length of nearly nine feet. This one joins the exhibit at about two and a half feet long and 66 pounds.

August 31, 2018 - Three young pelagic stingrays have recently been added to our Open Sea exhibit. This ray hunts small fishes, squid, jellies and shrimp in the open ocean, unlike most other rays that seek food near the sandy seafloor. This active predator can often be seen feeding upside down, grasping food in its very sharp teeth, and sometimes using its pectoral fins to manipulate food into its mouth.

Watch this intelligent invertebrate taking a sucker-powered stroll around its den on our YouTube Channel.
August 1, 2018 - We're celebrating our sea otter Rosa's 19th birthday—and the incredible life she's had over those years. She was found stranded as a four-week-old pup, and has gone on to rear 14 pups herself—the most of any of the moms in our surrogate program!
July 2, 2018 - A third scalloped hammerhead shark has been added to our Open Sea exhibit. This beautiful shark is between one and two years old. For the past year, it's been growing up at our off-site Animal Research and Care Center, but now is big enough to join the community of fishes on exhibit. The unmistakable shape of this shark's head is believed to help it track its prey, possibly by improving its sensory perception. The adaptation also appears to increase its agility and maneuverability over other shark species.
