Invertebrate Surveys
 The
Reef Watch Invertebrate Survey method is known as a
belt transect survey. Divers and snorkellers follow
a 50m transect line and record certain mobile invertebrates
and cryptic (hidden) fish that they observe within one
metre to one side of the transect line.
The
invertebrate survey method is described more fully in
the Reef
Watch Invertebrate Survey Manual, which should be
read in conjunction with the Reef
Watch Site Manual.
The
invertebrates sighted can be recorded directly on the
Reef Watch invertebrate
slate.
Reef Watch has provided an on-line
information resource about these invertebrates,
including identification notes.
  The
key reference for Reef Watch invertebrate identification
is Australian Marine Life - the plants and animals
of temperate waters, by Graham Edgar, 2000, Reed
New Holland (or 1997, Reed Books). The author has kindly
allowed us to use illustrations from that book on the
Reef Watch invertebrate slate and website.
