In The Field: Periwinkles - Duration: 2:24.
Welcome to the abyss.
Today we're in the field exploring the rocky intertidal habitat.
We're looking at the common periwinkle.
Let's dive in.
It may not look like it, but the intertidal zone is an extremely hard place to live.
The animals that live here must be adapted to both living underwater and on land.
For many hours of the day they're underwater and have to be able to breathe and find food.
For the rest of the day, they have to survive above water conditions and survive desiccation
or drying out, as well as the hot temperatures of the sun.
One animal that is well adapted to this environment is the common periwinkle Littorina littorea.
They are a mollusc and are basically just an ocean snail.
They are commonly found in the intertidal zone of temperate waters.
When they are underwater periwinkles come out of their shell and crawl along the ocean
floor and along rocks.
They use a tooth like structure called a radula to feed on diatoms and certain species of algae.
When the tide goes out and periwinkles are left on land, they try to find and area to
hide with as moisture as possible, such as tidal pools, the cracks in-between rocks and
under a bed of seaweed.
They then attach themselves to a rock, tuck themselves into their shell and seal themselves
off from the external environment.
Periwinkles also have a structure called an operculum.
This is a calcareous flap which that they can use to seal off the opening of their shell.
These adaptations allow for periwinkles to survive desiccation and wait out until the
tide comes back in and they're underwater once again.
That's it for this episode.
If you want to see more in the field videos let us know in the comments down below.
As always thanks for watching and remember to like and subscribe.
Until next tide, I will sea you later.

How To Help Your Cat Get Used To Their New Home | Tips To Settle a Cat In A New House - Duration: 4:12.
Hi guys! Welcome back to the channel it's Claire and Rags and as you can see Rags and
I have finally moved into our new home. Now with moving with a cat there are
going to be some troubles and some issues now I've talked about packing
with a cat and a travelling with a cat and this week and me and Rags are going to be
talking to you about how to help your cat to adjust to their new home. Now obviously
this new environment for everybody - you and your cat, but it might
be a bit more difficult for your cat to adjust correctly and to feel safe in the
new environment. So Rags and I have a few tips for you today to help your
cat feel safe and happy in their new home. Now first of all patience is key now
I feel like I use this tip for a lot of things when it comes to cats, but it is
absolutely true. Your cat will do whatever they want when they want and
at their own pace it may take a few weeks for your cat to fully adjust in a
new home so don't worry if your cat starts acting a lot skittish is a
little quiet use than usual. This is completely normal and they will get
better obviously if this behavior goes on for more than 6 weeks then
they might need a bit of attention from the vet. Secondly you have to keep your
cat in. Now this is the number one thing that that people tell you when you move
in a cat is to keep them in between two and three weeks especially if your cat
is one that likes to go outside. Now this might be frustrating for your cat and
for you because you'll have to listen to your cat complaining about being indoors
all day and but it is very important and looking dominum out at all this is
because your cat and it does have some heavy instincts so if they get out
before they're used to this home they might try and get back to their own
place or they might get themselves lost if they're feeling a little bit scared
of their new home. So it is important to keep your cat in so that they do eventually
see their new home as their new home now whilst your cat is indoors they will get
bored so to combat this boredom make sure there are a lot of toys
for them to play, give them a lot of attention a lot of grooming session a lot of
playtime. Thirdly your cat needs somewhere safe that they can go to. Now
the first two days that Ragsy was in this new house she spent it in my closet
now this isn't usual behavior for her but I wasn't worried your cat is in an
unfamiliar environment and needs to have somewhere where they feel safe and
comfortable. Now either let your cat find a safe space on their own - obviously
somewhere safe or you can create one you can use a box and one of their
blankets just make sure that is very near to their water their foods and
their litter box. And lastly if you can try spend some quality time with your
cat. Try spending a few hours of quiet time with your cats - just you and them
ma be give them a groom or place play with them or just sit somewhere
quiet. In a new environment you and your family are the only familiar thing to
them so you are going to be a big source of conflict and security for them. So if
you spend some time with them it's going to make it a lot easier for your cat to
adjust to their new home. Thanks for watching guys I hope you found these
tips useful now if any of you guys are moving house with a cat and have any
extra tips for me please let me know in the comment section below
Ragsy will pick a favourite if they're any good ones and you can win they relax my cat t-shirt
now in this new home that we have it is not just Rags who is a
resident cat. There is another cat in this home too! Now don't worry I'm going
to be doing a vlog all about introducing cats together as we have been
introducing Rags to Godiva who you may have seen in my last vlog. We are

the results for you in a vlog in January. So keep your eyes peeled for that! Thanks
