The Ant’s Neck

A critical part of the ant’s anatomy is its neck, which has to bear the full weight of loads grasped in its mouth. Soft tissues within the ant’s neck bind with the stiff exoskeleton of its thorax (body) and head in a manner that mimics the interlocking of fingers in folded hands. The design and structure of this interface is critical for the performance of the neck joint. The unique interface between hard and soft materials likely strengthens the adhesion and may be a key structural design feature that enables the large load capacity of the neck joint. Researchers hope that a clear grasp of how the ant’s neck functions will contribute to advancements in the design of man-made robotic mechanisms.

A 500 mg. weight is the equivalent of 1 paracetamol tablet.

New research on heavy-lifting ants reveals that the neck joint of a common American field ant can withstand pressures up to 5,000 times greater than its own body weight.

A sea otter

 

The fur of the sea otter is denser than that of any other mammal, with some one million hairs per square inch (155,000 per sq cm). When the otter swims, its coat traps a layer of air close to its body. That air acts as an insulator, preventing the cold water from coming into direct contact with the animal’s skin and sapping its body heat.

Scientists believe that there is a lesson to be learned from the sea otter’s fur. They have experimented with a number of artificial fur coats, varying such factors as hair length and hair spacing. The researchers have concluded that “the denser and the longer the hairs are, the dryer or the more water-repellent the hairy surface is.” Put another way, sea otters can boast a truly efficient fur coat.

Researchers hope that their studies will lead to technological advances in the design and production of novel water-repellent textiles
