Build a motorized predator of the deep

Bring the unmistakable shape of a hammerhead shark to life with the MJI 13154 Mechanical Hammerhead Shark.

Built from 1,323 pieces, this impressive mechanical model combines the streamlined form of a hammerhead shark with exposed engineering, mechanical linkages and futuristic detailing.

Once completed, the shark measures approximately 40.7 cm long and features both motorized mechanical movement and integrated lighting, transforming the finished build into an interactive display piece.

Motorized mechanical movement

Activate the powered mechanism and watch the Mechanical Hammerhead Shark come to life.

The internal motor drives a carefully constructed mechanical linkage system, turning the engineering inside the model into part of the experience rather than simply hiding it underneath the exterior panels.

The combination of visible mechanical components and powered movement makes the finished model particularly appealing to builders who enjoy engineering-focused construction sets.

Integrated lighting

Built-in lighting enhances the shark's futuristic mechanical appearance.

Switch on the illumination together with the powered movement to create an atmospheric display that highlights the model's cyber-inspired design.

1,323-piece mechanical build

With 1,323 individual pieces, the Mechanical Hammerhead Shark offers a substantial building experience.

The construction combines structural elements, gears, axles, mechanical linkages, body panels, fins, tail components, electronics and display-support elements into one integrated model.

Over 40 cm long

The completed model measures approximately:

40.7 × 20.3 × 22.4 cm

At more than 40 cm from head to tail, the Hammerhead Shark offers impressive shelf presence while remaining practical for display on a desk, cabinet or shelving unit.

Distinctive hammerhead design

The broad hammer-shaped head immediately gives the model its characteristic silhouette.

The design recreates the key features of a hammerhead shark through a futuristic mechanical interpretation, including:

• Wide hammer-shaped head
• Streamlined body
• Large dorsal fin
• Pectoral fins
• Long segmented tail
• Exposed mechanical structures
• Futuristic armour-style body panels

Visible mechanical engineering

The internal engineering forms an important part of the completed model.

Gears, axles, connectors and mechanical linkages remain visible throughout the build, giving the shark the appearance of an engineered robotic creature rather than a conventional animal model.

Dynamic display construction

The supporting structure elevates the shark above the display surface, helping create the appearance of the mechanical predator swimming through the water.

It also provides a stable foundation for operating and displaying the model's motorized movement and lighting system.

ABS building-block construction

The model is constructed primarily from durable ABS plastic building components.

The interconnected structural and mechanical elements provide the rigidity required for the model's larger dimensions while supporting its moving functions.

Specifications

Important information

This product is supplied as an unassembled motorized building set. Product images showing the completed model are for illustration.

The electric motor powers the internal mechanical linkage system and creates movement in the completed shark.

Carefully follow the assembly instructions when constructing the gear train, axles and moving components.

Before activating the motor, make sure all moving components can move freely and that no parts are obstructing the mechanism.

If the mechanism becomes blocked during operation, switch the model off before checking or adjusting the moving parts.

Do not manually force motor-driven components while the motor is operating.

Keep fingers, hair, loose clothing and other objects away from moving mechanical components during operation.

The motor and lighting components are electronic and are not waterproof. Keep the completed model away from water and excessive moisture.

Support movable sections close to their connection points when adjusting the model manually.

Switch the model off when it is not being used.

Clean the completed model using a soft, dry cloth. Avoid water, solvents and abrasive cleaning products.

Contains small parts and is unsuitable for children under three years old. Recommended age: 8+.
