Fleas Order Siphonaptera

Tiny wingless specialists built for movement, attachment and survival among the fur and feathers of their hosts.

Fleas are highly specialised insects with laterally compressed bodies, powerful hind legs and intricate combs, spines and mouthparts. This collection reveals the remarkable structures that make them among the most efficient jumpers and parasites in the animal world.

A closer look at Siphonaptera

Built to move through another animal’s world.

Fleas are compact, resilient and extraordinarily well adapted to life among hair, fur and feathers.

Their narrow bodies allow them to slip between hairs, while backward-facing spines and comb-like structures help them resist being dislodged.

Enlarged hind legs store and release energy for explosive jumps, allowing fleas to travel many times their own body length in a fraction of a second.

Under magnification, their armour, sensory structures and specialised mouthparts reveal an unexpectedly intricate anatomy concealed within an insect only a few millimetres long.
