Acorn worms (Enteropneusta) are an unusual component of deep-sea benthic environments, important for nutrient cycling. This dataset quantifies their distribution, abundance, and trail-forming behavior from two large-scale deep-sea mapping surveys along the eastern and western continental margins of Australia. It provides the first evidence of strong depth-related distributions for this taxon within Australian waters.
Use Cases
- Modeling depth-related distribution patterns based on survey locations.
- Analyzing trail-forming behavior as an indicator of benthic activity.
- Studying the role of acorn worms in nutrient cycling within deep-sea environments.
- Mapping species abundance across continental margins.
Strengths
- Data originates from two large-scale deep-sea mapping surveys.
- Provides the first quantified evidence of acorn worm distribution and behavior in Australian waters.
- Focuses on a taxon previously thought to be a missing link in chordate evolution.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last metadata update is 2026-04-16.
