Low Tide: 1.4' @ 12:22 PM

Saturday was a gusty day at Haystack Rock. Visitors, volunteers, and HRAP staff alike were hunkering down in rain coats and walking at angles into the wind. Even with high surges, low exposure, and high winds visitors still sought out the tide pools. Our highest count during the shift was 17 people in the intertidal.

There were few creature sightings during the day, however Junior Volunteer Alanna had an exciting encounter! After spotting a Western Gull (Larus occidentalis) scavenging something in front of the  HRAP truck, Alanna went to get a closer look. As she approached, a Bald Eagle (Haliaeetus leucocephalis) swept in just in front of her and snatched whatever the gull had been feeding on. An exciting site to see!

We are looking forward to more fascinating encounters this season so keep checking back for more updates!

Nudibranchs in the Tidepools

Nudibranchs, also referred to as sea slugs, can frequently be spotted in the tidepools at Haystack Rock. There are many species of nudibranch, most having outstanding markings and colors. The nudibranch feed on bryozoans, hydroids and sponges and it's color can be changed by the food it eats.   The nudibranch has a pair of sensory projections on their head, called rhinophores, which allow them to smell and taste. Virtually all nudibranchs have some form of eyes but they are not well developed and in most cases are little more than a pigment spot in the head near the rhinophores.  The nudibranch breathes through gill projections which extract oxygen from the seawater. The Pacific Northwest has more than 200 species of nudibranchs. The Opalescent Nudibranch ( Hermissenda crassicornis ) could be called 'showy'. It is found from Alaska to Baja, California and can grow to two inches in size. At Haystack Rock, it can be found in the sandy bottom of a tidepool. It is slender wit

Spring has sprung at Haystack Rock and with it volunteer and staff Environmental Interpreters are finding loads of eggs and tiny juvenile recruits of different types. There have also been very interesting sightings of more precarious types that come with warmer weather; read our HRAP "nature notes" to learn more.... Tidepool Sculpin, Oligocottus maculosus , eggs  Bright yellow Tidepool Sculpin, Oligocottus maculosus , eggs can be found among the barnacles and mussels, often above the tide pools during low tide. Sculpin can vary in color from red-brown to green  and can grow up to 9cm long. Acorn Barnacle, Balanus glandula , recruits  Tiny, juvenile Acorn Barnacle recruits dot the intertidal like adorable polka dots. These animals have small, white volcano-like shells and are very common in the tide pools at Haystack Rock and elsewhere along the Oregon coast. Barnacle Nudibranchs, Onchidoris bilamellata , and eggs Highly camouflaged Barnacle Nudibranchs
