I also saw birds: (gulls and this bird), not a Finch as first thought, but it was a Sparrow
(identified from Golden Guide Families of Birds)We then took a walk over to the Barking Crab.
He is measuring tides to ensure accuracy of the tide charts.
- Lots of mussle shells and mussels in what seemed like different stages of development.
I determined the large empty shells were Blue Mussels. Not sure, but seems like the smaller ones were baby Mussels. The small bugs in the water were plankton and other small animals the mussels eat.- We also found a seaworm (Clam Worm) and a Longhorn skeleton shrimp
Pink Shrimp Two types of plants
The one on the left is a sea lettuce called Umbraulva Olivascens (researched at Michael Guiry’s Seaweed Site)
My drawing of the plant on right which is Fucus Spiralis Linnaeus, also researched at Michael Guiry's Seaweed Site)
Most tunicates feed by filtering sea water through pharyngeal slits, but some are sub-marine predators such as the Megalodicopia hians. Like other chordates, tunicates have a notochord during their early development, but lack myomeric segmentation throughout the body and tail as adults. Tunicates lack the kidney-like metanephridial organs, and the original coelom body-cavity develops into a pericardial cavity and gonads. Except for the pharynx, heart and gonads, the organs are enclosed in a membrane called an epicardium, which is surrounded by the jelly-like mesenchyme. Tunicates begin life in a mobile larval stage that resembles a tadpole, later developing into a barrel-like and usually sedentary adult form.
Tunicates apparently evolved in the early Cambrian period, beginning c 540 million years ago. Despite their simple appearance, tunicates are closely related to vertebrates, which include fish and all land animals with bones.
This was a good day - time to go to bed.
