Otariidae
Otariidae is the most control-oriented tacky rubber in the Haifu range. The soft sponge keeps the ball on the sheet longer, so technique work and controlled looping are easier than on the firmer Blue Whale sheets, while the tacky topsheet still teaches proper brushing contact.

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.
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.

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
- Very high control
- Good for technique training
Weaknesses
- Low top-end speed
Best for
- Developing players
- Technique training
Not ideal for
- Power attackers
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
3 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
Offensive club and league players who want a spin-first inverted sheet on the forehand or backhand.
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
Dolphin
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.
Long pipsOctopus
Haifu's long pips, offered as an OX sheet or with a thin sponge for chopping and disruptive blocking.
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.
