Just in time for the end of Shark Week! Our sweet, female swell shark laid eggs! Swell sharks are bottom dwelling sharks. Females lay two green/amber colored egg casings. There is only one embryo per egg casing. A single yolk sack supplies the embryo with nutrients while it develops. It will be about 12 months before they are ready to hatch.

A large fish, rare to the Oregon Coast, was found on Sunset Beach this morning. The 3.5 foot, 100 lbs Opah was reported to the Seaside Aquarium at 8:00 a.m. After seeing photographs of the unusual fish they quickly responded and recovered the fish. It created quite the stir at the Aquarium where folks were encouraged to come take a look at this beautiful and odd looking fish. Always on the lookout for new educational opportunities, the fish will be frozen until the school year starts. Partnering with the Columbia River Maritime Museum's educational director, Nate Sandel, one lucky school group will get the chance to dissect this large fish. While rare this far north it is not unheard of. According to OregonLive a 97 pound Opah was caught 37 miles off of the Columbia River Mouth in 2009. Opahs can grow to over 6 feet and weigh over 600 pounds. They inhabit pelagic (meaning they live in the open ocean), tropical and temperate waters where they feed on krill and squid.

We have very exciting news! The Guadalupe fur seal we recovered is doing great! The entanglement had not gotten to the point where it was embedded into his skin, which means he did not have any external injuries. Though he is a little under weight, he is very active and alert. He was flown down to a rehab center in California for further observation. While there, they will fatten him up before his release. A huge thank you to everyone involved in his rescue, recovery, and release!

A Guadalupe fur seal, a threatened species, was reported as entangled to the Seaside Aquarium at 11:00 a.m. on July 3rd and was resting on the beach when reported. When the aquarium came on scene the fur seal had crawled onto an offshore rock, responders had to wait for the tide to go out before attempting to capture the animal. Once the rock became accessible they were able to safely get to the animal, capture it, and place it in an animal carrier for transport. The fur seal will be transported to a licensed rehabilitation facility for a full veterinary health assessment, disentanglement, and stabilization. If all goes as planned, the animal will be released back into the ocean once it is healthy. The fur seal was originally reported on July 1st but before the aquarium could respond a well-meaning member of the public attempted to remove the entanglement and the animal fled back into the ocean. The aquarium would like to remind everyone that even if it seems like a good idea, it is best to let trained responders deal with marine mammal emergency situations. If you see a marine mammal trapped in netting the best thing you can do for the animal is give it plenty of space, keep dogs away, and call the West Coast Marine Mammal Stranding Network at 1-866-767-6114. Seaside Aquarium partners with Portland State University and NOAA's West Coast Marine Mammal Stranding Network to respond to strandings on the Oregon coast. Since 1995 Seaside Aquarium and Portland State University have spearheaded the Southern Washington Northern Oregon Marine Mammal Stranding Network, a collaboration of experts and volunteers to respond to stranded marine mammals along the southern Washington and northern Oregon Coast. Through this program, locally stranded Guadalupe fur seals are able to be recovered and transported to rehabilitation centers. For more information on Guadalupe fur seals visit:

Walking along the shoreline you might come across some of these guys. They are a species of salp called, Salpa fusiformis. What is a salp? In order to understand the salp you must first understand the tunicate. Tunicates belong to the same phylum as vertebrates. Though as adults they do not have a backbone, developing larvae posses a tail, a dorsal nerve cord, and a dorsal stiffening structure (not composed of bone) called the notochord; because of this tunicates are thought to be more closely related to vertebrates such as fish and people. So what is a salp? A salp is a pelagic tunicate. Meaning they are tunicates that drift in the mid-water of the ocean. They move by means of jet propulsion, and feeding is accomplished by pumping plankton-laden water through the body where a mucous net is used to extract food particles. They can be found individually or in large aggregations consisting of millions of individuals.

Did you meet Barnacle Bill? An elephant seal, dubbed Barnacle Bill became quite popular when he decided to haul out on multiple northern Oregon beaches over Memorial Day weekend, filling both visitors and locals with concern for his wellbeing. Since he created quite the stir, we thought we would give you all an update on his travels and current condition. “Barnacle Bill” first showed up on Falcon Cove beach on May 17th. While he was lively, he did not look so good. He was going through his annual molt which is a process where he sheds his old coat of fur and grows a new one. During this process large hunks of skin will often come off along with the old fur. This can create large sores and open wounds, but it is a natural process. He also had patches of pelagic gooseneck barnacles growing on his back and flippers, hence his new name “Barnacle Bill”. When molting, elephant seals haul out. The saltwater irritates their open wounds and they have a hard time regulating their body temperature. Being out of the water allows them to warm up and get some well needed rest. This is exactly what Mr. Bill was doing. He spent a few days at Falcon Cove before continuing his tour of the north coast. His next stop was Arch Cape. He arrived in Arch Cape on May 20th but by May 23rd he headed down toward Rockaway and spent a few nights on the more secluded, Nedonna Beach. Looking for a little more attention, Barnacle Bill set his sights for Cannon Beach and during the busy Memorial Day Weekend camped out right in front of Haystack Rock. Staff from the Haystack Rock Awareness Program did a wonderful job watching over him, making sure people and dogs did not disturb his peace. They also educated people about him, alleviating fears that he was dying and needed help. After the busy holiday weekend Barnacle Bill headed back south where he discovered Manzanita. By this time some of his open sores from the molting process had started to heal and was beginning to look more like a “normal” seal again. On June 1st Barnacle Bill left the beach for good. Over the two weeks that he visited we received a lot of calls from concerned citizens and with the help of State Parks and the Haystack Rock Awareness Program we were able to educate people about the natural process of molting and help give him the space and rest he needed to heal and get better. We are so thankful for all our partners and this wonderful community.

Shark Week Seaside Aquarium Style: This week the Seaside Aquarium partnered with the Columbia River Maritime Museum to give students an opportunity they will not soon forget. On Thursday, June 3rd Warrenton 8th graders participated in the dissection of a 3-foot salmon shark. The shark was already deceased when it washed ashore on the south end of Seaside Beach in October of 2020. They took measurements and samples of the shark’s liver and muscle which will be sent to the Hatfield Marine Science Center and used in further research. Another opportunity was afforded to Eisenhower Elementary School on Saturday, June 5th. This enthusiastic group of 5th graders dove right in to dissect a 7-foot broadnosed sevengill shark. Like the salmon shark, the broadnosed sevengill shark was deceased before washing ashore on the south end of Gearhart beach on March 31st, 2021. Both groups were amazing and engaged. It was a blast just to sit back and watch while these non-squeamish kids got a once in a lifetime hands on experience. They asked great questions, and everyone got their hands dirty. The dissections were led by Columbia River Maritime Museum’s educational director Nate Sandel, also known as “Nate the Great”. We will often get a call through the Marine Mammal Stranding Network when a shark is found dead on the beach and while they are obviously not marine mammals, we do our best to try to respond and document the event. If the shark is in good enough condition, it will be recovered and frozen in the hopes that it can be used for educational experiences just like this.

The Seaside Aquarium and the Columbia River Maritime Muesum partnered to give local kids the chance to learn about and dissect a broadnose sevengill shark. The shark was deseased by the time it washed ashore and was collected in the hopes that this exact thing would be possible. These are the types of educational experieces that will stay with the kids for a long time and we are elated to be a part of it. Sorry the video got cut short, there were WiFi issues.

On May 25th, 1937 the doors to the Seaside Aquarium opened for the first time! Today we are celebrating our 84th birthday! The building that currently houses the Seaside Aquarium was constructed in 1924. When it opened for business in the fall of that year, it was actually as a salt water bath house and swimming pool named the “Seaside Baths Natatorium”. The natatorium closed in the early 1930’s, underwent major renovations, and in 1937 opened as the Seaside Aquarium. Looking at the Aquarium from the beach in 1937, there was a lunch bar in the south-west corner (the present site of the gift shop). In 1938, apartments were added upstairs. They were called the Sea Water Apartments. Some of the apartments are still there, but are no longer used. The Seaside Aquarium is the oldest privately owned aquarium on the West Coast. The owners and staff of the Aquarium would like to thank you for your support throughout the years. Without you, the Seaside Aquarium could not have been successful for so many years.

Seal pups are popping up left and right! If you come across a seal pup on the beach be sure to give it plenty of space to rest and if there are not signs already posted give us a call (503) 738-6211. Remember 99% of the time their moms are close by and will not come back to nurse the pup if people are around. The pup may stay in the same place for several days with the mom coming ashore at night to feed it. At the moment we are monitoring three different pups in our stranding area. Oregon and Washington typically see harbor seals born throughout spring and into late summer, while California may see pups early as February. These young animals use time on land to regulate body temperature and rest while their mothers hunt nearby. However, the mother may not return if humans are too close. Thus, wildlife experts suggest giving seal pups plenty of space, observe them from a distanced and while they are absolutely adorable do not touch. Female seals birth annually after an eleven-month gestation and utilize familiar coastal shores or estuary areas with easy access to water to have their pups. New seals can immediately swim but stay close and ride on their mothers back while they mature. Baby seals often double in size from birth in 4-6 weeks on a regular diet of mother’s milk with 40% milkfat. While the extra layer of fat make the pups adorable, the pups depend on that stored body fat to survive foraging on their own as they become more independent. Any interference from humans that could cause early separation between newborn pup and mother could be detrimental to the pup’s ability to survive.

We are asking for some help tracking this little harbor porpoise down. The porpoise stranded itself on Sunset Beach on Tuesday morning. Unable to get the four foot porpoise out past the surf, it was decided that his best chance of survival was to get him into the deeper, calmer waters of the Necanicum River mouth. Once in the deeper channel he seemed to swim around quite well but he did come to the ashore a few more times. He was last seen yesterday morning near the mouth of the river. We are hoping that he got enough rest in the estuary that he was able to make it back out to the ocean. If you do see a harbor porpoise in the Necanicum River, please call us the aquarium. There is also the chance that this guy was suffering from an infection that went to his brain and that in the end he will not make it. If that is the case, while sad, it is important for us to recover him so that we can preform a necropsy to confirm what happened.

The local beaches are teaming with wildlife! This afternoon we responded to a juvenile molting elephant seal, came across a heard of elk enjoying the dunes, and multiple species of migratory seabirds such as sanderlings and whimbrels. It is always a good reminder that all of these magnificent creatures call the beach their home. This is where they go to rest, feed, and breed! When we returned from checking on the elephant seal we had a surprise waiting at the Aquarium for us, tiny cute ducklings! These guys had lost their mother and were brought to us so that they could be transferred to the Wildlife Center of the North Coast.

It's Fishy Friday! Every Friday we pick a different species of fish that lives along the Oregon Coast to highlight. China Rockfish (Sebastes Nebulosus) In our humble opinion these are one of the most attractive species of rockfish out there. They can vary in color from black or blue-black, mottled with yellow and sometimes white. Like other species of rockfish, they have a relatively long lifespan, often exceeding the age of 70. The aquarium currently houses three China rockfish, all of which have resided at the aquarium for over 20 years. They can be quite territorial and are not much for traveling. Usually most active at dusk, they do not travel further than 20 or so feet from their established territory. They prefer complex habitats like boulder fields or kelp beds and are sometimes found living in dens or caves occupied by giant Pacific octopus.
