Hi Caroline:
Belize: numerous sites, including Rhomboid reefs, Southwater Caye,
Tobacco Caye, Twin Caye:
S siderea, S. radians, M meandrites, P astreoides, P porites, D
strigosa, M cavernosa, M ann complex spp., Agaricia spp., Scolymia,
Oculina, Tubastraea, Phyllangia, Manacina, Millepora spp., Stylaster,
Distichopora
San Salvador Bahamas: S siderea, S. radians, P astreoides, P porites,
Agaricia spp., Scolymia, Phyllangia, Manacina, Millepora spp (in a
single 45 minute snorkel)
This is what I recall or have photos of, and I think from the sites I
have seen beyond these, the amount of settlement observationally
rather depends on the location of the mangroves in terms of open water
exposure and location relative to nearby reefs.
