Bryozoans

Bryozoans

Bryozoans are colonial animals of uncertain evolutionary descent. They may be related to freshwater rotifers. Bryozoans are found in the lower intertidal to subtidal zones, attached to a firm substrate, and also in brackish water. Individual animals are too small to see with the naked eye.

Bryozoan growth forms range from encrusting, forming coatings on hard surfaces, to bushy. An entire colony may bear a superficial resemblance to a hydroid colony, although bryozoans are internally more advanced than cnidarians. Bryozoan colonies grow to 3", and are occasionally larger.

Brown Trout

Brown Trout

Salmo trutta

Size
to 41"

Although not native to North America, the widely-introduced European Brown Trout is the most common trout in our area. It thrives in poorer water conditions than native species. Salmon are very similar to trout but generally larger. Introduced from Europe to much of the United States during the late 1800s, the brown trout has adapted well, tolerating warmer water than the native brookie. Sides have a light brown or yellow cast with black spots and usually some orange or red spots. The spots often have whitish to bluish halos. The tail generally lacks spots but may have a few.
