I noticed lots of beige Membranipora villosa or Kelp-encrusting Bryozoan on kelp during the -2.1 minus tide today, mostly large colonies up to 4" across and on tattered fronds of kelp. These two small colonies, each 1" across, attracted my attention because of their freshness and contrasting colors-- golden and blue.

gelatinous blob on a submerged twig is quite characteristic for this species of freshwater bryozoan.
I'm wondering if this is Rhynchozoon rostratum aka Yellow Enrusting Bryozoan? I found it encrusted on a rock in the low intertidal zone. Each colony (?) is about 1-3" across. Those are very tiny baby Thatched Barnacles growing on the rock among them.
The Bryozoa, also known as Polyzoa, Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia. Most marine species live in tropical waters, but a few occur in oceanic trenches, and others are found in polar waters. One class lives only in a variety...
