You think you know what it is \u2013 but what is it?<\/u><\/strong><\/p>\n

Walking along the beach at Bribie (any of them \u2013 Bribie has lots of beautiful beaches!) – there, among the shells and seaweed, the pumicestone and cuttlebone, is something\u2026..what is it? …  a jellyfish ? \u2026 a piece of broken jellyfish?..<\/p>\n

\"\"<\/p>\n

No, that\u2019s the egg mass of the leaden sand snail<\/u> –  Wow, look, there are lots of them! The leaden sand snail is as common as mud \u2013which is just where you\u2019ll find it \u2013 on the sand and mud flats all along the Pumicestone Passage. It\u2019s not a very big snail, only about 5cm across the shell.  What is amazing is the enormous size of some of these egg masses. They can be up to     25cm in length, and you can see how fat they are!<\/p>\n

Pick one up \u2013 it\u2019s perfectly safe \u2013 you\u2019ll see tiny brown dots inside the \u201cjelly\u201d. These are the eggs, thousands of them in each egg mass. Only a few days after they are laid, they hatch into little squiggly babies.<\/p>\n

How does something as small as a leaden sand snail lay something this big? Easy- it lays the eggs in a thin, gelatinous rope, which then swells up when it absorbs the seawater.<\/p>\n

 <\/p>\n

Further along, there\u2019s something else \u2013 again like a jellyfish, but perfectly round like a marble.. . Oh, watch out – is this one of those box-jellies or an irukandji??!\"\"<\/p>\n

It\u2019s okay, don\u2019t panic, you\u2019ve just found a sea gooseberry<\/u>! Not actually related to jellies, the sea gooseberry is completely safe, so you can gently pick it up for a proper look. Practically invisible in the ocean (or a bucket of water \u2013 try it), this marvellous little creature has rows of tiny hairs that move the sea gooseberry through the water.<\/p>\n

You can see it\u2019s a bit dark right in the centre \u2013 from here, two long, fine tentacles can stretch out a long way; they are very sticky and drift in the ocean catching tiny, tiny sea creatures for dinner! Put it gently back in the water and along a few metres, there is another mystery\u2026<\/p>\n

 <\/p>\n

Something interesting is rolling around at the water\u2019s edge. It\u2019s squirting out bright purple ink. Not a terrifically pretty creature – it\u2019s fat and blobby, with wings along each side.  What on earth is this??\"\"<\/p>\n

This is a Sowerby\u2019s sea hare<\/u>, a type of sea slug that loves to wander the ocean floor, grazing like a cow. Every now and again, lots of them will come ashore and get stranded on the falling tide. Our little mate, Henry, loves to \u201crescue\u201d them. He scoops them up in a handful of sand and takes them back into the water. He\u2019s careful not to touch, because some people get a mild rash from Sowerby\u2019s sea hares. Usually, when one gets dropped back into the ocean, it lets out a great cloud of purple ink \u2013 fabulous fun, but be warned- don\u2019t let any get in your eyes!<\/p>\n

Sometimes you might find a small shell on the beach, a little like a fragile pipi shape. This could well be the internal shell of the Sowerby\u2019s sea hare \u2013 that\u2019s right \u2013 they wear their shells on the inside.<\/p>\n

If you check out Youtube, there is a great video of a Sowerby\u2019s sea hare, moseying around the Pumicestone Passage!<\/p>\n

 <\/p>\n

Wandering along past the jetty, you can see some round things lying at the bottom, in the water below. Oh dear, look – lots of dead jelly-fish! Are they? \u2026. really? \u2026 or are they the upside-down jelly<\/u>? Yes, exactly \u2013 upside-down jellies, because that\u2019s how they like to live.<\/p>\n

\"ImageUpside-down jellies can swim like a regular jelly-fish but prefer to spend their lives sitting on the floor of sheltered places, with their legs in the air (water). This is because special algae live on the jelly\u2019s tentacles, which need sunlight and photo-synthesis to make food, for the jelly.<\/p>\n

The upside-down jelly isn\u2019t really dangerous but it is just as well not to touch it, because their tentacles can sometimes give a little sting and might cause a rash.<\/p>\n

 <\/p>\n

Here\u2019s something else you might see on the beach, and especially when swimming, which can give you a NASTY sting and leave you with a rash. They don\u2019t turn up often at Bribie but when there is a blue-bottle<\/u> on the beach or in the water, it\u2019s always a good idea to know what you\u2019re looking at.\"Image<\/p>\n

The blue-bottle is not one animal but actually a colony of four different types of animal, more like a household than a jelly-fish. There is the bladder-animal, there are tentacle-animals, a stomach-animal and a reproductive-animal. They all get along together and have a great time stinging us, if we\u2019re not careful!<\/p>\n

A couple of things to remember, if you\u2019re planning a swim:<\/p>\n

    \n
  1. If there is a north-easterly blowing at Woorim, keep a lookout for blue-bottles; check the Surf Lifesaving information board, which will generally tell you if there\u2019s been a problem with blue-bottles.<\/li>\n
  2. If you get stung by a blue-bottle, pull the tentacles off your skin, rinse your skin with salt water then apply hot water (45degrees) for about 20 minutes. NO cold water, NO ice, NO vinegar.<\/li>\n<\/ol>\n

    Don\u2019t worry, it won\u2019t hurt forever, just take some time out and have another walk along the beach.<\/p>\n","protected":false},"excerpt":{"rendered":"
