Abstract: 1. Nerinides acuta is an efficient burrower, building semi-permanent vertical burrows in the sand using its acutely pointed prostomium, while secreting a mucous layer along the anterior third of the body. 2. N. acuta is a non-selective herbivore feeding with its tentacular palps by grabbing food and bringing it to its mouth. It feeds on the plant material washed up on the beach, and moved to the worm by wave action. 3. N. acuta appears capable of breaking down cellulose. 4. The population of N. acuta studied inhabits a narrow tidal range in very dense clusters. 5. It has definite lower and upper limits to its distribution. The upper limit is likely determined by physical factors of water coverage while it is speculated that predators determine the lower limit.
