Bryozoans characteristics.

Bryozoans. Introduction. The Bryozoa, also known as Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals that resemble corals. They are found in marine, brackish and freshwater habitats. Marine species are common on coral reefs but a few occur in oceanic trenches, and others are found in polar waters..

Most fossil "eggs" are weathered and rounded rocks, rather than fossils. siderite nodules and concretion s can have smooth, oval shapes and may appear like eggs. Other rocks may be rounded in streams into oval shapes.ECTOPROCTS ARE THE BRYOZOANS OF OLD. The colonies of many ectoproct species are plantlike in appearance. They were once given the name of moss animals and placed in the phylum Bryozoa. The name Bryozoa comes from the Greek words bryon, meaning moss, and zoön, or animal.

Copper Sulfate or “blue stone” is probably the most commonly used algal treatments because of its availability and low cost. Copper sulfate comes in several forms depending on how finely it is ground.
