The fresh new Hamelin cockle is a great bivalve you to is one of the phylum Mollusca, plus oysters, snails, and you may squids, to mention a few. It’s native to the latest low coastlines of West Australia, although it are prevalent from inside the Shark Bay and Layer Coastline.
Shark Bay is actually a good hypersaline marine ecosystem. Their seagrass bedrooms limitation tidal direction, while the speed from evaporation exceeds the pace regarding precipitation, which makes the water very salty. Indeed, water try plankton-lacking as large salinity will make it hard for plankton so you’re able to survive.

The whole organism try below 20 millimeters, that is a small smaller compared to an inches.

The fertilized eggs turn into zooplankton one drift doing on the water ahead of it settle to your crushed and further end up as cockles.
I’ve found such bivalves to get most of the interesting. They registered Shark Bay more than 4000 years back and extremely place onward the hassle to help make the bay and Shell Beach its home. Really lifestyle things do not do well from inside the extreme criteria, particularly in aspects of large salinity. But not, the newest Hamelin cockle just modified to your hypersaline liquid, even so they prospered very incredibly which they left a noticeable draw about regional geology.
Five thousand years’ property value cockle shells changed the exotic beach from Cover Coastline. It blows my brain to trust how profitable this type of lightweight little bacteria is actually, and this means they are special!
