PREDATORS - Book II

Hi Sea Fans!

Yes, it's here, it's finally here!!  The next book in the series is looking stunning - it's worth it just for the pictures.

Join me on my next adventure in the aquarium world and you'll soon discover that sharks aren't the only predators in the sea.  Find out how sneaky, how cute, how beautiful and how strange-looking some predators actually are.  It's an amazing world down below where SCUBA divers love to go.

It's not in the book stores yet so if you'd like to be one of the first to have a copy, contact Heidi at abby@telkomsa.net and she'll sort one out for you.

Have an amazing week Sea Fans.  Enjoy the book - you've got to sea it to believe it!
Cheers

Interview with a pro

Hi Sea Fans!

It's a beautiful day and I love what I do so here is an interview with a professional in my field to tell you more about what goes on in the aquarium world:

Professional: Becs Smith

1. What is your job? Assistant curator at Bristol Aquarium, UK.
2. What did you study/do to get this kind of work? BSc Hons Marine Biology at Newcastle University.  I did a year and a half internship at Mote Marine Laboratory Florida working in their sea turtle exhibit.
3. What do you do in a normal day? First thing I do is to check the systems and the fish.   I make sure that the exhibits are ready for the public.   I make a list of jobs for the team to do throughout the day,  have a meeting, sort out any problems, place any orders needed, do systems, backwashes, water changes, maintenance on pumps etc (if needed) and update record systems.
4. What is the most interesting thing you've come across/experienced in your job? Setting up 2 aquariums from the beginning - Dubai Mall Aquarium and Underwater Zoo and Bristol Aquarium - getting all the livestock in and seeing the end result.
5. What is a not-so-nice thing about your job? Losing animals.
6. What do you love about your job? Learning about new animals and making a great exhibit. Right now I am speding time on our coral display learning their requirements and geting it right.
7. What would you say/recommend to kids who want to do what you do? Try and get as much experience as possible. Volunteer at the local aquarium or do an internship. Experience is what people look for, my internship got me my first job!

I hope you found that interesting, it's amazing how much goes on in an aquarium.  Keep an eye out for more interviews, I'll keep posting them inbetween the updates and stories.  Have a great week Sea Fans and for those of you in the southern hemisphere - enjoy the last bit of warmth before Winter sets in...diving is going to get colder! : )

Cheers

Schools

Hi Sea Fans!

Keep a look out for me, I'll be at Herschel Girls' School tomorrow, Woodstock library next week Tues and Wynberg International School on 8 April!  Yes, talks can be arranged at your school.  The author, Heidi, will tell you all about me and what I get up to and show you some interesting goodies.  Contact Heidi at abby@telkomsa.net if you'd like to book her for an event at your school (teachers and parents to contact please).  Heidi also takes me to birthday parties if you'd like to do crafty things with a sea theme.

Enough of that though, I want to tell you about what happened at the aquarium this week.  It was Pirate Week!

As you can see, the staff all got dressed up as crew of the pirate ship - quite funny really, especially seeing as the penguins took to pulling at the outfits and stealing one of the aquarists' swords!  He really shouldn't have taken it into the enclosure with him but I guess he's learnt now not to take unnecessary loose items in with him.  The animals weren't only stealing OUR things, but the public's too!  The catfish managed to swallow a pair of glasses!  Someone was leaning over the tank and they fell in, so Bobcat (the catfish) promptly swam over and swallowed them thinking that they were food.  A hysterical volunteer came running up to me to tell me about it, but luckily another aquarist had seen it happen and reacted quickly.  A little bit of net movement in the water made Bobcat spit the glasses out - shew!  Please do me a favour - if you're in an aquarium, make sure that you don't wear your glasses on your head, don't put your hands in the water and don't drop or throw things in the water....and PLEASE don't bang on the windows.  We also had a few excited members of the public bashing the otter window to get them to wake up.  It's not nice to disturb the animals... AND they scratched the window with their jewellery.

So it was an eventful week once again.  Oh yes, a weird looking animal came in today too...I'll let you know what it is next time.

Have a great week Sea Fans.
Cheers!

Cockroaches of the sea

Hi Sea Fans!

Yes, believe it or not, there is something living in our oceans that is very similar to a cockroach.  Anyone scared of cockroaches?  Well, the ocean cockroaches can get bigger than 200kg!!!  How's that for scary?!
Want to know what I'm talking about?.....Nomura's jellyfish!

Photo: CORAL Magazine

These guys seem to be taking over the oceans and the possible reasons that the scientists give are:
Overfishing; Declining water quality (yucky water); and Rising sea temperatures (warmer water).

In the Sea of Japan, the numbers of these jellyfish have suddenly increased more than ever.  Since 2002, the Nomura Jellyfish population has exploded SIX times!! In 2005, as many as 20 billion jellies filled the Sea of Japan, causing losses in the fishing industry. 

Predators, like many fish and turtles, eat jellyfish, but jellyfish eat fish eggs and sometimes fish too.  So if too many fish are taken out of the sea by humans, jellyfish can take their place in the food chain and take over (Jellies and many fish eat the same thing - plankton).

Photo: CORAL Magazine

These jellies can also live in water with lowered oxygen levels, which most fish can't (fishies need to breathe!).  Increased temperatures and nutrient (food for plankton) levels cause lower oxygen levels.  Increased nutrient levels also mean increased food for the jellies.  So it looks like right now, with global warming and nutrient run-off from the land into the sea, we could be in trouble...Nomura jelly trouble.

There are several thousands of species of jellyfish, but these Nomura jellies are the ones who cause a problem - they reproduce like mad, grow fast, eat almost anything and can swim around in yucky water which most fish can't do.  This is why they are like cockroaches!

It's possible that nature will sort itself out and the jellyfish populations will become a normal size again (other jellyfish have been through this before), but we don't know so it's actually quite scary.  Let's hold thumbs that the scientists find out soon.

Have a great week Sea Fans!

PS. Do you know that jellyfish eat Sea Monkeys? : )

PREDATORS

Hi Sea Fans!

It's been a scorcher the last few days, our air conditioning in the aquarium has had to work overtime!!  Not to mention the chillers for the tanks!  Well, I hope you're all doing well and getting ready to read about my next adventures because Book II is coming out this month. 

Publishing books is an expensive exercise and I'm always looking for companies who are willing to sponsor a print run or part thereof so that I can keep the price of the book at a decent level. New Era joined me on this next book as a part sponsor because they believe in Marine Education.  Check out their website (http://www.new-era-aquaculture.com/home.html) if you're looking for good fish food!

Speaking of hot days and wanting to cool down, have you ever wondered what it's like to be the opposite: an animal who has to live in ice and snow?  Well, if you'd like to know how marine mammals are adapted to the cold, try this:

• Get a bowl of water with ice cubes in it.
• Put on a rubber glove and stick your hand into the water for a while (not too long!) - time yourself if you'd like.
• When you can't stand the cold anymore, take your hand out of the water and glove.
• Take butter and smear a layer over your hand and then put it back into the glove and then back into the ice water.

Can you feel a difference?  Amazing what fat can do to keep you warm, right?  Blubber is a layer of fat that marine mammals, like seals, have under their skin to keep them warm.

So on a beautiful hot day, appreciate that you don't have that layer of blubber but on the cold days...hmmm, you'll just have to add more layers!

Have a great week Sea Fans and don't forget to write.
Cheers

Aquarium Valentine

Hi Sea Fans!

I hope you all had a great Valentine's Day.  We had such fun at the aquarium...we had to come up with ideas for Valentine Sea Crafts and the best one would be used as the activity for the day in our Ocean Crafts Centre.  Next year maybe you'd like to try this one:

A loving Fiddler Crab.

The heart body is filled with small chocolates (2 hearts joined around the edges back-to-back make a purse).  Have fun being crafty and don't forget that all sorts of marine craft kits are for sale, just mail me at abby@telkomsa.net.

Have a great week Sea Fans.
Cheers
Abby

PS. Predators (Book II) is at the printers so you can start saving your money for a copy when it comes out next month!  New crafts will also be available.

Squirt squirt blow!

Hi Sea Fans!

Strange title I know, but you'll understand in a minute.

I was explaining something to members of the public yesterday and realised that I haven't told you guys about it.  Do you know that fish like the boxfish blow at the sand to uncover their food?  Well, do you want to know something even more interesting? .....Our boxfish got used to food dropping into the water from the surface so what he started doing was spitting water at us like a fountain (blowing the water surface for food).  Cute, but this is of course not what we wanted, so we had to make a plan.  Now our boxfish gets food buried under the sand and he loves it!  Instead of blowing water at the surface, now he blows the sand like he naturally would and the public get to see how boxfish feed out at sea.

Just another little morsel of behind-the-scenes information for you. : )
Have a great week Sea Fans.
Cheers
Abby
