Moose antlers (or simply antlers, or moose) is a 15-cell still life. It is composed of two fishhooks with a single cell between them.
Occurrence
- See also: List of common still lifes
Moose antlers is the thirty-third most common still life in Achim Flammenkamp's census, being less common than cis-mirrored bun but more common than block on table.[1]
It is the 35th most common still life on Adam P. Goucher's Catagolue, being less common than cis-mirrored bun but more common than block on table. It is the most common still life with 15 cells, being about 7 times as common than cis-boat on dock.[2]

As a catalyst
There is a reaction where a 17-cell form of moose antlers gets hit eater 3-style, turning it into the 15-cell form. A domino spark restores it to its 17-cell form. A period-40 oscillator discovered by Mitchell Riley on July 26, 2022 is shown below.

Glider synthesis
All strict still lifes with a population of 22 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
