Description There is a rich and varied bryozoan launa al several foreshore localities
along the northeastern coast of India. At Visakhapatnam, abundant
growths of bryozoa were observed. in dense bands. measuring as much as
80 em in width on the under· and verti cal surface of rocks. Detailed
investigations were conducted on the Quantitative aspects of bryozoan
distribution and zone pauerns in intertidal regions at two stations at
Visakhapamam. The results obtained are presented in this paper. The
study revealed that bryozoa are conspicuous faunules in lower midlittoral
to infralittoral zones occupying considerable areas or protected
and semiprotocled rock surfaces. The tidal ranges of individual species
and their relative abundance were estimated. A luxurient and distinctive
" bryozoan band", consisting primarily of Thalamoporella gothica var.
indica, Hippopetraliella magna, and Steganopordlla buskii was discovered
and incorporated into a tripanate zone pattern. Our study, the
first of its kind from tropical shores. clearly indicates the quantitative
significance of this important but hitherto little investigated group of
organisms in tropical-shore ecology.
