Are these some form of dinos ?

[Abhishek]

Hi,

I have this algae growing on my rocks. Filamentous, brown in color, comes of easily with scrubbing .
they are over my sand bed too.
Will be getting some more Trochus snails but wanted to confirm if they are some form of dinos ? if so, hardly any impact by snails.

The bubbles are from the micro scrubbing I have just started yesterday .





Regards,
Abhishek

Ohh.. no snails have died yet from eating them even though they are on the rocks with the algae.
