Huntsman Spider

It's a well-known fact that Australia is infamous for its spiders, and with good reason. 


They're pretty scary looking, have shiny hairy bodies and eight legs!


Unless trapped behind a glass enclosure, even fearless Aussie children, like my grandson, is a bit leery of them.


I hadn't intended on capturing a Huntsman spider on this day. 


But if you read many of my posts, you know that I just let life happen when I'm in Sydney, and something astonishing usually does.

It was a warm Spring afternoon, and our doors were wide-open. 


For some reason, Aussie homes don't have screen doors, which I don't understand since this is Australia. 


I would want screens around everything!


While walking past the open doorway, I noticed a Huntsman spider on the top of the roller blind.  


I've developed a special knack for spotting critters I don't want to see.  


I knew a Huntsman spider flattens its body to get under doors and windowsills, and because our door is near a window, I was able to figure this one out.


Door open - no screens!


I surprised myself and didn't panic . . . this time. 

After all, this was not my first dance with a Huntsman. 

Once I woke up in the middle of the night to discover one getting ready to crawl up the wall.  

I didn't sleep at all that night!

Another time I noticed one through the window that appeared to be trying to make its way to the window pane.

It's comforting to know that they are non-aggressive unless provoked, and I wasn't about to do that!  

Besides, I've never actually heard of them crawling or dropping down on people - my worse fear!

They have venom, but it's considered low-risk, nontoxic to humans.
 

A bite may cause swelling and minor pain, and an ice pack and a topical anesthetic are all that is needed to treat it.


To avoid the unnecessary stress of dealing with the spider myself, I quickly texted my daughter, who was on her way home from work, to ask her to hurry!

Then, I sat patiently staring at it -  willing it not to move till she came home.

She arrived within minutes, rushed in, and asked where it was. 


Lucky for me, she's a real Huntsman spider trapper!


I was happy to point out its location. 


She pulled the shade down a bit, startling the critter, and it was on the move.

Without blinking an eye, she placed a water glass over it, abruptly stopping its descent, slid a piece of cardboard underneath, and captured it in a matter of moments.  


What a pro!

The Huntsman is a massive brown hairy spider with a one-inch flat body and eight legs banded and twisted, enabling it to spread them to advance forward and sideways in a crab-like fashion. 


They are often are called crab spiders.  




They molt to grow, and their old skin can be mistaken for the actual spider. 


When they are not inside, they live under loose tree bark and in rock crevices and feed on insects and other invertebrates like mosquitos, cockroaches, and sometimes geckos and small skinks. 


They come inside to grab a couple of common household insects and to escape Sydney's hot summer weather.


Some Aussies like to keep them as housemates because of their passive temperaments and appetite for household pests like roaches - not happening here!


Just looking at them makes me squeamish!

As their name suggests, they are true hunters.


They do not construct webs to catch prey.


Instead, they stalk their target, run it down, then pounce.



Like all spiders, they are nocturnal and can get into cars at night, so be sure to close car windows and doors.


They hide behind sun visors and steering wheels and scuttle out, startling drivers going 50 miles an hour on the freeway. 


Knee-jerk reactions have caused car crashes.



The mere sight of this enormous spider is the stuff of nightmares, and the movie industry made it the star of their 1990 horror-comedy thriller Arachnophobia.


Named after the debilitating fear of spiders and other multi-legged creatures, many people have Arachnophobia, and many more are just plain afraid of spiders and don't know why. 


These eight-legged critters just freak us out!


While filming the movie, the Landcare Research organization in Auckland flew three hundred Australian Huntsman spiders to the set every two weeks. 


They were selected because they're scary-looking yet nontoxic and relatively harmless. 


Fortunately, unlike the movie, only one comes in the house at a time. 


The Movie



There are 1,207 species of the huntsman spider in the family Sparassidae, and 155 of them are in Australia.

  

Spider experts have identified 4,000 other species, with another 8,000 more still a mystery. 


Aussies love their native animals and critters - harming them is never an option. 


They believe that the huntsman spider deserves a place alongside koalas and kangaroos and, therefore, should be treasured. 


So my daughter took it outside to set it free in a nearby bush  - which is the recommended way to remove spiders from the house.


If you swat a pregnant spider,  it could release 200 spiderlings before dying.  


The redback, funnel-web, trap door, mouse, white-tailed, recluse, and tarantula spiders are dangerous and deadly, and if one of those had gotten in the house, this would have been a very different story.

Bluebottle Jellyfish Swarm

Beaches that are both beautiful and dangerous line the Sydney coastline.  On a recent trip to Manly Beach with my daughter to buy roller skates from a seaside skate shop, we heard the following message over the public address (PA) system:


Attention swimmers!  Swarms of stinging Bluebottle jellyfish are washing up by the bucket loads.  We cannot provide any emergency medical services at this time and ask that you swim at your own risk!  There is no cure for the sting.


The announcement repeated every hour.  After buying the skates, our curiosity led us down to the beach to see what was going on.  We didn't have to go far before noticing the creepy blue shimmering bubbles strung together in clusters stretched along the sandy shoreline - a.k.a. bluebottles.


Bluebottles on Manly Beach

These are colonial jellyfish with several colony members connected to one main tentacle. It was fascinating and disgusting.  Each individual colony is named for its particular purpose such as feeding, reproducing and stinging. Yipes!


Several varieties of Bluebottles wash up on the Australian and New Zealand coastlines every year.  Luckily for us in Sydney, we most often get the smaller and least dangerous variety.


They look like half inflated translucent bubbles topped with floats that act like sails. Tossed about by the wind, they move in with the waves and out with the tide.  Some of the Bluebottle's colorful parts are purple in open water and blue on the sand - common hues for sea creatures that live on the ocean's surface.  The combination of their materials, illumination and coloration, acts as a camouflage when they are floating on top of the water, making them extremely effective hiders and hunters.  The same matter somehow protects them from UV damage.

While on the beach, dead or alive, the Bluebottle's powerful stinging cells - some of which are invisible - remain active. When the tentacles come in contact with skin, even for a moment, they deliver a painful sting.  The venom in their tentacles can travel to the lymph nodes and joints so it is important, if stung, to remove them quickly.  

Rather than using your fingers to prick them off, use a stick, knife, fork or any nearby object.

If you get this far without freaking, out continue to use caution. Sudden movement when removing the tentacles will cause them to release more venom, resulting in additional pain.  Similar to hives, nasty red welts (as shown below) are the body's reaction to being stung.  



The sting is not life threatening, but can cause further complications for those who are young, old or allergic so it is important to immediately wash the affected area.


Old fashioned trestments included a vinegar wash, because of its acidity, or a urine rinse, for the same reason.  In most cases you probably won't have any vinegar in your beach bag and peeing on a jellyfish sting, for most people, is a bit gross.


According to the Australian Resuscitation Council, washing the area with sea water (there is plenty of that at the beach) followed by a hot or cold shower is 50% more effective than all other treatments to alleviate the pain which can last for an hour or more.

My daughter and I saw a teenage boy coming out of the water holding onto his leg and hopping around in pain - obviously a Bluebottle victim.  Later that day, I read in the local news that over 50 people had been stung, just that morning, at another nearby beach.  We were careful not to step on the critters.


Sydney-siders have every right to boast about their beautiful beaches, in spite of the Bluebottles.  The picturesque views encompass clear ocean water, golden & white sandy shores, naturally carved rock pools, overhanging cliffs and beachside swimming pools.


Behind the beaches are rows of trendy shops, restaurants, bars, and quaint villages nestled in hills of varying heights.

But this is Australia . . . and if you are coming from the US, i.e. Kansas, expect the unexpected, like the shark fence, in the picture below, for swimmers who want to splash around in a shark free environment.

It was a hot day in Sydney.  Temperatures were expected to reach a scorching 43C or 109F later that day.  Despite the heat, we decided to leave the beach to the Bluebottles and head home where my daughter could try out her new skates.

I must admit though, I was not sure which activity was more dangerous since she had not been on a pair of roller skates for twenty years.
