Description: Found this morning at Estero Bluffs state park, at the pretty pocket beach at the mouth of Villa Creek. Which we had pretty much to ourselves. Way cool to walk in the footsteps of Dr. Darwin! OK, walk FAR back from Darwin's footsteps! But he did love barnacles! These little guys are maybe 1 1/4 in high x 1 in diameter. I don't know the limpet(s). There are a LOT of limpets! Barnacles spend their lives (15 years?) standing on their heads, with their feet sticking out in the water to grab their dinners. This group is firmly cemented to our ubiquitous greywacke sandstone, which weathers golden brown. Date: 13 May 2020, 10:28. Source: Pink volcano barnacle, Teraclita rubescens Darwin 1854.
