The February 2025 report describes intended work—not confirmed discoveries of rare, new, or missing species.
What the announced mission plans to do
According to The Daily Galaxy’s February 21, 2025 report, Minderoo Foundation announced the initiative with the IUCN at the second annual eDNA conference in Wellington. The plan is to analyze 10,000 samples and assess 600 marine species across Australian and New Zealand waters.
The reported goals are to map where those species are found, identify places where they may no longer be detected, and compare results with historical data to track changes over time. The figures describe the announced scope; the report does not say the samples have all been analyzed or that the goals have been achieved.
How eDNA can reveal which species may be present
Environmental DNA, or eDNA, is genetic material organisms shed into water or other surroundings. Researchers can collect water without first seeing or capturing an animal, then examine the genetic traces it contains. NOAA Ocean Exploration’s eDNA explainer describes the typical workflow:

- Collect and document water. Researchers record where and under what environmental conditions a sample was taken.
- Filter and preserve it. Material is separated from the water using a filter, and the sample is frozen or otherwise preserved.
- Sequence the genetic material. The sample is processed to read DNA sequences.
- Compare sequences with reference databases. A technique called metabarcoding helps label sequences and compare them with known records. Identification may be possible at the family, genus, or species level, depending on the available information.
Because it can detect traces without requiring a direct encounter, eDNA offers a non-invasive way to investigate which organisms may occur in an area. NOAA describes it as a complement to other forms of observation and sampling, including work on biodiversity and possible invasive or endangered species.
What an eDNA detection can—and cannot—tell researchers
| Evidence | What it can support | What it does not establish by itself |
|---|---|---|
| DNA detected in a water sample | Evidence that genetic material associated with an organism was present in the sampled environment. | A direct sighting or capture of the animal, its exact location at the time of sampling, or a population count. |
| A sequence matched against a reference database | An identification to the level supported by the sequence and available reference information. | A species-level identification when the database or sequence cannot support one. |
| No DNA detected in a sample | No detection in that particular sample under the methods used. | Definitive proof that the species is absent from the wider area. |
In other words, eDNA can help map evidence of species occurrence, but it is not a direct measure of abundance. A non-detection should not automatically be treated as proof that a species has disappeared. The initiative’s reported aim to find areas from which species may have disappeared is a question for analysis and comparison, not a result already demonstrated.
Why researchers want better marine biodiversity records
The Daily Galaxy report presents the project as a response to gaps in knowledge about marine species and their populations—gaps that can make conservation assessment harder. It quotes Michael Bunce, director of Minderoo’s OceanOmics program, describing “dark biodiversity” and species that have not yet been described. That is an attributed statement in the report, not confirmation that this initiative has discovered a new species.
The report also mentions threatened white sharks, sawfish, and hammerheads in a general discussion. It does not identify these animals as a complete or confirmed target list for the initiative, so they should not be read as promised mission subjects.

Has the mission found rare or new sharks and fish?
The February 2025 account describes planned analysis and possible scientific value, but it does not report completed findings or verify discoveries. It also does not establish the initiative’s status or results after that date. “Rare” and “hidden” describe the motivation and possibility behind the work, not a confirmed outcome.
