moulting
Let an agent explain moulting across animal groups, relay its biology and control, describe patterns in birds, mammals, reptiles and arthropods, and distinguish moulting from other forms of skin and coat change.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain moulting across animal groups, relay its biology and control, describe patterns in birds, mammals, reptiles and arthropods, and distinguish moulting from other forms of skin and coat change.
The periodic shedding and replacement of an outer covering by an animal, such as feathers in birds, hair or fur in mammals, skin in reptiles and amphibians, and the exoskeleton in arthropods, where it is called ecdysis; moulting allows growth, repair and seasonal change, is controlled by hormones and environment, and leaves animals temporarily vulnerable.
What it is for: Growth, repair and seasonal adaptation of coverings.
It can be explain the process across groups; relay hormonal and environmental control; describe patterns and timing; distinguish from related processes.
Distinguishing features
Periodic and often seasonal
Hormonally controlled
Group-specific patterns
Vulnerability during moult
What it looks like
Shed feathers, fur, skin or exoskeletons, and animals with patchy or new coverings.
How it is recognised
Periodic shedding of an outer covering
Feathers, fur, skin and exoskeletons
Continuous hair shedding and wound healing are different processes

What the second pass must settle

- How should zoological references be linked?
- The registry entry has merged aliases naming group-specific forms; should they be split off?
