Hi, we're here today to take you on a tide pool tour at Scripps.
My name is Olívia and I'm a PhD student here.
Hi I'm Dani. I'm also a PhD student here.
Hi everyone. I'm Anaí Novoa and I'm also a PhD student here.
Hi, I'm Kayla Wilson. I'm a fifth year PhD student here at Scripps.
So here we're looking at a Pisaster seastar
and they're really cool because they're
called keystone species.
It's also really cool to see this one right here and that big,
because we thought they were disappearing from the Scripps tide pools.
So it's actually a really great sighting.
Some of these hermit crabs are quite specialized to use certain snails.
This is the blueband hermit crab.
It is notorious for using Tegula snails' shells.
This is a Spanish shawl nudibranch which is a type of sea slug.
Sea slugs are notorious for stealing the defenses of food it eats.
For seaweeds, you typically have greens and reds and browns.
This is a brown seaweed, one of my favorites.
This one is called the feather boa kelp is the nickname or common name.
The holdfast is down here.
And if you look the holdfast has like little finger-like projections,
and it's like goal is pretty much just to hold on for dear life,
so it doesn't get swept away.
This is a combination of gooseneck barnacles
and California mussels.
So in combination with the rocks,
these guys can help to sort of break up some of the impact of larger waves,
and they're both filter feeders.
They're really good at pumping water in and out of their bodies,
and taking all the edible items out of that water.
We're looking here, it's the sandcastle worm,
and you can see that it's a polychaete,
it's a worm that creates these tubes and they live inside the tube and there's a
lot of animals that can live within the tube as well.
That's in the crab.
They’re very territorial and they'll
start gurgling a lot.
So here we're looking at a sea hare,
also known as the brown sea hare,
the California sea hare.
And it's feeling around for food.
It takes these oral tentacles and touches rocks and seaweed around it to find
things to eat and what's around it.
This right here, the light orange is an ascidian or a sea squirt.
And then this stuff right here, that's a sea sponge,
that's some sort of encrusting sea sponge.
Chitons are molluscs, which is pretty funny because when you look at them,
you don't think they are.
And what's really cool about them
is that they make these depressions in the rocks
and then at night they go out
to feed and during the day they go back
to their own depressions to stay there during the day.
When you are grabbing an organism, make sure that you
have a little cup of water for them.
These organisms are typically inundated
which means they’re typically under the water.
You always wanna make sure you're careful about where you're stepping.
Always look before you step and try not to step on anything that
might be disturbed, like
anemones or barnacles or mussels.
And always be sure to check to make
sure you're not gonna step on something
sharp or unstable so you don't hurt yourself.
This rock here is covered in sea anemones.
You don’t think so because they’re
actually holding shells above them.
Don't be afraid to bend down and really get in the crevices to look for these organisms.
A lot of the time, they are hiding in these crevices
because that's where they feel safe
and it’s very moist with lots of water.
You need to get down and all fours and
really bend and take a good peek
in where you’re looking,
because something might be hiding there that's really cool.
