It's over with anyway, be thankful. We're thankful for
you, in any case.

Keeping up with the mail daily it doesn't feel like such
a gigantic echo. But it is pretty unrelenting, and if you
miss a week or two or more, you can feel swept away by
the tide.

Sea Food Foraging

Porphyra nereocystis
Porphyra nereocystis is epiphytic (real close neighbor to) on
the Bullwhip Kelp, genus name Nereocystis. Porphyra as most
know it, is commonly called nori. If you eat sushi, then you
have probably seen Porphyra. It's the seaweed that your
uncooked fish is wrapped in at the sushi bars. Porphyra,
commonly know as nori, is the most widely consumed seaweed in
the world! It's commonly found in Asian food, especially
Japanese food, which has lead tthe huge nori industry in
Japan. With a very interesting heteromorphic life history,
Porphyra has just everything you would want in an alga! And
they're great to eat!

Nereocystis luetkeana
Otherwise known as the Bullwhip Kelp, Nereocystis is one of
the giant kelps that make the great kelp forests, where sea
otters and other critters live. Washed up on the beach they
may look like dismembered tentacles of mythic sea creatures,
or horrendously huge pieces of spaghetti. They have been used
to weave baskets and also make great musical instruments.

Pelvetia compressa
Pelvetia compressa (now Silvetia compressa) is a common rocky
intertidal brown alga on the west coast of North America
ranging from Coos Bay, Oregon to lower California (Ensenada).

Pelvetiopsis limitata
Resembling a dwarf Fucus, and even behaving like Fucus (if
one were to believe that algae can behave in specific manners
at all), Pelvetiopsis grows mostly atop of rocks in the upper
intertidal zone. One way to distinguish these two from each
other, is to look for a midrib. Fucus has a midrib and
Pelvetiopsis lacks the midrib. Also, believe it or not, if you
squeeze the receptacles (swollen tips) of Fucus, an ooze will
come out. This ooze undoubtedly contains Fucus eggs which if
you have microscopic vision, you can see that the eggs are
composed of 8, yes count them 8 functional eggs. Pelvetiopsis
on the other foot, only has 1 functional egg.

Iridaea flaccida
Greek myths describe Iris, the goddess of the rainbow, as a
messenger for the Olympian deities. The characteristics of the
alga Iridaea flaccida strikingly reflect its namesake. The same
properties of light which produce a rainbow provide Iridaea's
surface with its brilliant iridescence. Vibrant colors wash
across the thallus surface due tthe multilayered construction
of its cuticle. Flaccida subtly manages to communicate its
phase of life history to the casual observer--yet it lives
an isomorphic existence. Both its iridescent cuticle and the
differences in blade strength between its life phases provide
insights into the adaptations of wave-swept algae to mechanical
stress.

Ulva fenestrata
Ulva is very common along California in bays as well as heavily
exposed sites and easily recognized by the small holes in the
thallus. Ulva is a genus of algae that includes species that
look like bright green sheets and live primarily in marine
environments. They can alsbe found in brackish water,
particularly estuaries. They live attached to rocks in the
middle to low intertidal zone, and as deep as 10 meters in
calm, protected harbors. Ulva are usually seen in dense groups.
Commonly known as the sea lettuce or the green laver, Ulva
species can be eaten in soups and salads, and used as a
substitute for nori (Porphyra), the popular seaweed in sushi.
Ten species of Ulva exist worldwide, all of which have
representation on the coast of California. The shapes of Ulva
are quite varied - circular to oval to long and narrow, ranging
in size from microscopic to 65 cm. They have fine, silky
textures with waved or ruffled margins. The delicate blades
of Ulva are usually only 40 microns thick.

Ulva taeniata
This alga characteristically has a ribbon-like thallus, and we
have found it growing abundantly in semi-sheltered habitats.

Postelsia palmaeformis
The common name of this seaweed is the "sea palm." It grows
on the tops of rocks in areas associated with intense wave
action. When they reach maturity, spores are produced that
slime off of the sharply attenuated blades during low tide,
where they then settle and differentiate.

Fucus gardneri
Fucus, pronounced like mucus, is a funny looking alga that
grows in the upper intertidal zone. The inflated ends are
called receptacles (these house reproductive parts, i.e.,
eggs and sperm), and they are fun to pop. But be careful,
because Fucus sometimes feels like mucus.
