Haifu · Haifu Marine · Long pips
Octopus
Octopus returns most of the incoming spin rather than generating its own, so it rewards a defensive game built on chopping, pushing and disruptive blocking. The OX version has no sponge at all and gives the most reversal; the thin sponged versions add a little pace and stability.

Specifications and evidence
Approval evidence and market availability are recorded separately. A commercial listing is not proof of current ITTF legality, and an approval listing is not proof of current production. Approval is never inherited by an edition, and no expiry date is invented.
Market status describes current commercial availability only. A sold-out button or a low-stock warning is a stock state, not a discontinuation, and where availability could not be verified it stays unknown.
Haifu states sponge hardness on its own degree scale. Those values are preserved verbatim and are never converted to an ESN degree.
No reliable official Haifu list price is published per region, so no price is shown rather than an invented one.

TTDNA values are TTDNA's own editorial 0–100 ratings. They are not official Haifu measurements and are never a conversion of the Haifu manufacturer scale.
Short pips, medium pips and long pips behave differently: short pips hit flat and generate some spin of their own, medium pips add wobble and partial return, and long pips mainly return the incoming spin. Generated spin and spin reversal are separate ratings.
Haifu also sells glues and boosters such as Sea Moon and the Blue Whale glue and booster products. Those are not rubbers, so they are excluded from this catalogue rather than mixed into rubber filters or comparisons.

Editions and factory tuning
| Edition | Official label | Factory tuning | Sponge hardness | Covered by approval | Evidence |
|---|---|---|---|---|---|
| Commercial | Octopus commercial | Untuned | Medium (TTDNA band) | Standard | Partially verified · Established specialist retailer listing |
Commercial, provincial, national and training editions are structured properties of one canonical product, never separate records. Factory tuning is stored per edition and is never inferred from an edition name, and an edition never inherits the commercial version's approval.
Factory tuning status is a separate fact from the edition level. Where no source states whether a sheet leaves the factory tuned, the status stays unknown rather than being assumed.
Strengths
- Strong spin reversal
- OX and sponged options
Weaknesses
- Very little generated spin
- Demands reading the incoming ball
Best for
- Choppers
- Disruptive blockers
Not ideal for
- Attackers who want their own spin
Data confidence
Generations are never merged automatically. Blue Whale I, II and III, White Shark I, II and III, and Pirates 07 and 08 are separate records, and no specification is copied between them.
Variants and configurations
4 variantsColour, thickness and configuration are variants of one model — never separate products. Colour never changes a rating, MAX and OX stay qualitative labels, and OX carries no sponge hardness.

Known users
Defenders, choppers and disruptive blockers who rely on spin reversal rather than their own topspin.
Haifu publishes no athlete roster for this sheet, so TTDNA shows the player profile it is built for instead of invented names.
Rest of the Haifu Marine family
Otariidae
A softer, control-first tacky sheet often used as a training rubber inside the Chinese system.
Short pipsDolphin
Haifu's short pips: a direct, low-arc sheet for hitting and punch blocking close to the table.
Medium pipsPenguin
Medium pips: longer than the Dolphin short pips, with more wobble and variation but still attackable.
Pips-out, geometry unresolvedO. Orca
A pips-out Haifu sheet whose exact pips geometry could not be resolved, so the rubber type is deliberately left empty.
Family membership groups related names. It never means shared construction, and family members are never merged into one record.
