The #Cambrian Explosion marks the first appearance of many animal phyla in the #fossil record, but just how radical was it? I'm starting a new #FossilFriday thread where I post Cambrian fossil representatives of one phylum per week. Join me on this trek across the tree of life 
Let's begin with #Annelida. In the #Cambrian these come mainly from deposits of exceptional preservation. Polychaetes and sipunculids, including species with potential affinities to living families, are represented.

Today, on #TheMisplacedMenagerie -
We report the exotic (for #India) apple #snail, #Pomacea diffusa, also known as the spike topped apple snail, from the #Mumbai region, as part of our ongoing studies on #urbanwildlife, and the #ecology of introduced species, in #India, Mumbai.

Spiked Topped Apple Snails in #Mumbai (and other parts of #India) are the direct result of the #aquarium trade - either as accidental, or deliberate releases from home aquaria.

Just back from another beach clean event, this one at Chessel Bay Nature Reserve, #Southampton. Thread...
At first sight, things look petty good. But start looking among and under vegetation and it's obvious that #plasticpollution is an issue. Lots of macro-litter, way more than can be collected in a single day..
Doesn't take long to collect a big bag of plastic crap. Only two syringes this time. The plastic fish are soy sauce containers. #plasticpollution
