marine mammal
Let an agent explain marine mammals and their groups, relay biology, adaptations and conservation from zoological sources, describe captivity and military use with positions attributed, and distinguish marine mammals from fish, from freshwater aquatic mammals and from semi-aquatic mammals.
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 marine mammals and their groups, relay biology, adaptations and conservation from zoological sources, describe captivity and military use with positions attributed, and distinguish marine mammals from fish, from freshwater aquatic mammals and from semi-aquatic mammals.
A mammal that relies on the sea for most of its life, comprising cetaceans such as whales, dolphins and porpoises, pinnipeds such as seals, sea lions and walruses, sirenians such as manatees and dugongs, sea otters and polar bears, with about 130 species adapted to swimming, diving and cold; marine mammals are kept in captivity in aquaria and have been trained by navies for tasks such as mine detection, both of which are debated.
What it is for: Not applicable; an animal group.
It can be explain groups and adaptations; relay biology and conservation; describe captivity and military use with attribution; distinguish related animals.

What the second pass must settle

- How should zoological sources be linked?
- The registry entry has merged aliases naming captivity and military contexts; should they be split off?
