How did this sweet girl turn so sassy? Vivian may officially be out of her teens, but she still has a teen's attitude. Today, Vivian turns 20 years old. Happy birthday, cheeky lady, we love you! (Shh, don't mention to her that it is also Frankie's birthday. She is not a fan of sharing her special day.)

The surf has been pretty big the last few days, generating sneaker waves and unearthing skin-breathing sea cucumbers (Leptosynapta clarki). It has also begun breaking apart the whale skeleton near Ave K.

Skin-breathing sea cucumbers can be seen littering the tideline on Seaside beach.
Lacking tube feet, these strange animals look more like worms than sea cucumbers.

They live just past the surf and burrow into the sand for protection. Most of the time, they are just fine, nestled down in the sand, but certain ocean conditions, such as heavy surf combined with low tides, can dislodge them, leaving them stranded along the shoreline, sometimes by the thousands. These stranding events provide a nutrient source for shore birds and small scavenging invertebrates.
