The sea is changing.
Document what matters.
Identify unfamiliar marine species. Explore published biodiversity records. Document an encounter with defensible evidence. Contribute responsibly to a real marine reporting network.
One platform. From sighting to science.
An integrated field workflow with transparent evidence provenance and no fabricated public activity. The Atlas is contextual data; submissions belong to the reporting platform.
Record a sighting
Submit observations to the existing multi-user backend; keep privacy and consent controls.
Evidence Passport
Fingerprint the original photo, review metadata and export privacy-aware research candidates.
Ocean Hazard Atlas
Investigate source-linked historical Mediterranean biodiversity occurrences with transparent filters.
Smart species ID
Interpret visible traits without mistaking guidance for independent expert verification.
Marine community
Share observations, discuss submissions and use the existing community account.
Research laboratory
Explore scientific export and analysis tools without conflating external datasets and local reports.
Coastal Survey Missions.
Run actual timed shoreline monitoring, preserve local encounter notes, record sampling effort and export candidate Darwin Core observations — with privacy controls and explicit consent before any real submission.
Explore marine hazard records.
Source-attributed published occurrences, not current hazard alerts. Filter species and encounter categories; inspect original records before drawing conclusions.
What the reference data can—and cannot—tell us.
A transparent breakdown of the currently loaded GBIF sample. Compare date coverage and source metadata, not species prevalence or population trends.
Records are not animals counted.
Occurrences may represent repeated sampling, uneven effort, different datasets and records with varying identification quality. This sample cannot estimate density, abundance, invasion speed or injury risk.
Know the species. Respect the sea.
A curated entry point to marine encounter hazards. Photo attributions link to external Wikimedia file pages, subject to source availability and license terms.

Use the Evidence Passport Studio to assess metadata completeness, fingerprint your original photo, protect sensitive positions and prepare a research-oriented candidate record. Then open the real reporting form to contribute to the existing platform.
- Source transparency and explicit uncertainty
- Local first, privacy-aware photo hashing
- Research metadata for ecological observations
- Accountable separation of proposed and expert-reviewed identification
- Existing network reports and expert review preserved
Observe safely. Report responsibly.
A scientific record should never come at the expense of personal safety. Know the distinction between dangerous consumption, venomous spines and stinging tentacles.
Do not eat unfamiliar pufferfish.
Some pufferfish, including Lagocephalus sceleratus, pose potentially serious poisoning risks. Do not attempt to identify edibility using a photo or this app.
Greek public-health reference ↗Never handle a suspected hazardous catch.
Maintain distance from lionfish, weever fish, scorpionfish and other spiny species. Avoid handling live, dead or unidentified specimens without appropriate training.
Open AegeanGuard Safety Center ↗Keep clear of tentacles.
Do not touch jellyfish, washed-up animals or detached tentacles. If you are injured or suspect poisoning, seek appropriate professional medical assistance promptly.
