Notes from the week

The HRAP team spotted lots of nudibranchs, or sea slugs, this week, including the leopard, shaggy mouse, red (or Rostanga) and opalescent. These animals are molluscs-- as are snails, chitons, limpets, clams, squid, and octopus! Most molluscs have at least a bit of shell-- one notable exception being the octopus-- and even most sea slugs have a shell in their larval stage. Sea slugs often specialize on a cnidarian (animals with stinging cells, like jellyfish and anemones). Not only are they undeterred by these animals' stinging cells (or cnidocytes) but they actually…

Notes from the week

Another busy week here at Haystack Rock, both for the humans and for the birds! Tufted puffins can still be seen guarding their burrows, and the black oystercatcher pair continues incubating their precious eggs, which should be hatching any day now. Oystercatcher hatchlings are precocious and able to leave the nest as soon as their downy feathers dry-- usually within about 24 hours of hatching; tufted puffin hatchlings aren't quite as mobile and must stay in the nest longer. Both species stick by their parents' sid…

Notes from the week

The unusually large beaching event of purple hydroid "jellyfish" known as Velella velella continued this week. A couple of other maritime creatures visited the shore as well, including a lion's mane jellyfish on Wednesday and a juvenile harbor seal on Thursday.

 Lion's mane jellyfish washed up on the sand.
In addition to these animals, the waves brought us some beautiful sand patterns.

Sort of an "art deco" sand pattern.
Sand patterns can be like a Rorschach inkblot test. One volunteer saw a scallop shell here. What do you see?
On Friday, we were also lucky enough to witness a hermit crab …

Notes from the Week

HRAP staff and volunteers worked extra hard this week covering double daily low tides. For tide pool enthusiasts like us, one of the joys of summer is good low tides and long daylight hours to take advantage of them. Another joy of summer is beautiful weather, which we've had in spades lately-- except for Wednesday, when multiple squalls, complete with bursts of torrential rain, interrupted one of our beach shifts. Kudos to our visitors for braving the bouts of bad weather with good humor and enthusiasm.

The d…

Notes from the week

Great weather and our lowest tides of the year combined to make this an excellent time to explore the tidepools at Haystack Rock. This post is going to mostly be a list and photos of some of the amazing creatures we saw!
