Locals and kids spent this morning with Dave making specimen/crab traps and testing them out off the dock. Mission successful!! Specimens including red rock crab, kelp crab, and sunflower sea stars were collected with the fine handcrafted traps.

Those visiting in the past few days would have seen the decorator crab in action as they begin dressing up disco-syle in their new tank:

Off the dock a lion's mane jelly was collected, spanning approximately 25 cm. This exciting scoop is the newest addition to the beautiful jellyfish tank already containing ctenophores, water jellies, and fried-egg jellies.

Recent collection outings were possible due to very low tides in the morning. The new specimens are settling well into their vacation-home and include urchins, sea stars, sanddabs, sculpins, snails, and more from our local area. As always community members have also been very helpful with their constant contribution of exciting finds.

Caylan and Dave carry back specimens from the beaches at low tide.

Touch tank studies concerning the possible effects of handling are nearly underway and will be continued for the duration of the summer. The intertidal touch tank will be the first to begin observations. As a result of tank-shifting, many of the Dungeness crabs were released and the moonsnails now reside in their own tank. This tank includes the sand collars left behind in the sand that contain moonsnail eggs. The clam shells with the characteristic hole left at the base near the hinge are also being created as hungry moonsnails eat up.

Make your way to the aquarium to check out all the critters and watch demonstrations from the staff! In the past week visitors from all over the world including England, Germany, Australia, and South Africa have dropped in to learn about our amazing ocean life. See you soon!
