*Update: A necropsy was preformed on the humpback whale that washed ashore on August 30th near Ocean Park, Washington. Like we suspected, there was no clear cause of death. It can be difficult to determine the cause of death with large whales, especially those that have been dead for quite sometime before washing ashore. What we can say is that it appeared to have a healthy layer of blubber and lots of food in its belly. I know a lot of people were concerned about plastics. No plastics were found.

Not exactly something you find everyday along the Columbia River. This six-foot Mola mola, also known as an ocean sunfish, was brought up river by yesterday's high tide. Mola mola are often found off of the Oregon Coast, especially in the summer but they tend to linger further offshore. These gentle giants can reach at least 8.9 feet in length and weigh over 5,000 pounds! There was also a report yesterday of one on the beach in Manzantia. So what's with all of the dead animals on the beach lately? As Fall begins and the weather starts changing things that have died out at sea get pushed around by heavier winds and surf. It is not unusual to come across a few dead animals on the beach after a storm.

A four-foot salmon shark washed ashore yesterday in Arch Cape. The little shark had died before washing in. Luckily, it was still in great condition and we were able to recover the shark. It will be dissected by a local school group and samples will be taken to help scientists learn more about these amazing creatures. Did you know 17 species of shark reside in Oregon’s coastal waters? From the legendary Great white to the large basking shark and the innocuous spiny dogfish, Oregon’s sharks are part of the complex ocean food web. During summer and fall months, Oregonians may notice juvenile sharks stranded on the beach. The salmon shark species is one of the most common species to wash ashore. Named for their diet preference of eating salmon, the quick-swimming salmon shark can become stranded throughout the year, but are most commonly found during summer months. Salmon sharks give live birth to 2-4 pups off the southern Oregon coast in the spring and the juveniles follow ocean currents and prey. While this species is able to thermoregulate (control their body temperature up to 15 degrees Celsius above surrounding water temperature) and navigate vertically throughout the water column, some juveniles end up outside their ideal temperature range and are unable to thrive. With an average length of seven feet and weighing in at 300 pounds, mature salmon sharks are quick enough to catch salmon, birds, squid and herring. With grey bodies and white bellies salmon sharks are often mistaken for the great white, but major differences in size, diet, and teeth patterns set the salmon sharks apart. Salmon shark teeth are notably pointed and smooth while white shark teeth are triangular and serrated. While the salmon shark may look fierce, there has never been a reported incident of a salmon shark attack on a human. If you have a question about a stranded shark or other stranded marine life, be sure to contact local experts at the Seaside Aquarium 503.738.6211.

A 43-foot humpback whale has washed ashore near Ocean Park, Washington. A necropsy will be scheduled for later on this week, however since this whale has been dead for quite sometime, determining the cause of death is unlikely.

Have you had a chance to visit the puffins at Haystack Rock in Cannon Beach? If not, there is still time but not much. Any day now the puffins nesting on Haystack Rock will depart for the open ocean where they spend the winter. The puffins are most active first thing in the morning. So, grab your binoculars and head on down before it's too late.

Our rubescens octopus is hiding more than just herself... A couple days ago we noticed that she laid eggs! She laid them inside of the barnacle shell she calls home and you can only see them when she is cleaning them. It will take about 4 to 6 weeks before they hatch. As larvae, they prefer to feed on hermit crab larvae which are not easy to come by, so we will be releasing the babies into the intertidal zone as soon as they hatch.

We came across a very sad scene this morning. Two pelicans were entangled in fishing line. While one was still alive, it appeared that the other pelican had drown and died. We were able to cut the fishing line and separate the pelicans, however the fishing line was embedded deeply into the live pelican’s wing, and he was unable to fly. Luckily, we were able to safely capture the injured pelican, which was taken to the Wildlife Center of the North Coast, a license nonprofit animal rehab center. If all goes well, this pelican will get the care he needs and released once healthy enough to fend for itself.

Thousands of live sand dollars are washing ashore on the south end of Seaside Beach. It appears that they are washing in during the afternoon high tides and getting stranded along the high tide line. They are still alive when stranded but are unable to make it back to the water once the tide recedes. This is resulting in them drying up and dying. At this time, we do not know what has caused this, and these types of incidents usually have several contributing factors. We are also unaware if this is an isolated incident or if this is happing on other beaches. It is hard to convey how many sand dollars on washing in. Clink here to see a short video: https://youtu.be/YVBSrlgQ1no Sand dollars are related to sea urchins. The outside of their shell is covered with millions of tiny spines which look like ‘fuzz’ or hair. These spines aid in the movement and feeding of the sand dollar. On the underside, in the center of the sand dollar is its mouth. A sand dollar’s diet consists of plankton, which they break down with their five small teeth. Each tooth closely resembles the shape of a bird, and many people refer to them as ‘doves’. Sand dollars are found worldwide and there are many different species, each with their own unique characteristics. How can you tell if a sand dollar is alive? The best indication would be if the sand dollar is still ‘fuzzy’. You may want to leave the ‘fuzzy ones on the beach, as they can smell quite badly if taken home.

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.

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.
