A rare, nocturnal monotreme mammal measuring 4 to 6 centimeters in length, this species is a specialized ectoparasite of large flying animals. Due to its inefficient energy use and strict parasitic lifestyle, it is considered vulnerable and possibly nearing extinction.

Etymology

From English bird + bat.

Morphology

This species is covered in short, soft fur ranging from dark gray to dark brownish-gray. Its wings also bear a sparse layer of very soft fur and are composed of thin, opaque skin. The wings are supported by four digits, each tipped with short, thin claws designed to minimize disturbance to the host. Its thin teeth are specialized in painless blood-sucking. A thin but wide tail, made of the same membrane material as the wings, assists in flight. The eyes are solid black, adapted for its nocturnal lifestyle.

Physiology

It suffers from inefficient energy use.

Diet

It feeds exclusively on host blood through brief but substantial feeding sessions.

Behavior

Life Cycle

Feeding sessions occur every 4 to 6 days.

Social Structure

This solitary creature locates hosts under cover of darkness.

Ecology

It attaches itself with claws and teeth to feed, then detaches and remains inactive until its next meal.
