Most macroinvertebrates found in the Sargassum beds are juveniles
--Juvenile gastropods have the most number of individuals collected.
Some adult echinoderms were spotted usually near the holdfast of the Sargassum spp. especially the sea urchins ( Salmacis sphaeroides and Tripnuestes gratilla)
The abundance of the fauna in seaweeds is also due to habitat preference and not just for the escape from predators (Bell and Destoby 2000).
The Sargassum beds located near the man-made island of the Maribago Bluewaters yielded 24 species of macroinvertebrates under 4 Phyla.
In terms of number of individuals, the Astraea calcar (Mollusca) and Tripneustes gratilla (Echinodermata) were the most abundant.
The Sargassum beds are important grounds for several juveniles that are vulnerable and susceptible to predators and they may provide food to different organisms in the coastal area.
Sargassum bed is essential ecologically because of its possible role in maintaining the biodiversity by offering food and protection to the juveniles.
Extensive sampling with the use of appropriate sampling methods to allow quantitative analysis of patterns observed.
Experiments on why juveniles are more attracted to the upper portion of the Sargassum.
