Claw with tail (or great snake eater) is a 10-cell still life.
Construction
Claw with tail can be constructed with 4 gliders.[1] Several known syntheses can be found in Mark Niemiec's database.[2]

Occurrence
- See also: List of common still lifes
Claw with tail is the seventy-second most common still life in Achim Flammenkamp's census, being less common than eleven loop, but more common than symmetric scorpion.[3]
It is the 76th most common still life on Adam P. Goucher's Catagolue, being less common than symmetric scorpion but more common than bee hat. It is the 11th most common still life with 10 cells, being less common than long integral but more common than trans-barge with tail.[4]
There are two three-glider collisions in the octo3g database[5] and two collisions in the octohash database[6] with claw with tail in the ash.
Catalysis
Claw with tail can be used as a catalyst; two distinct example reactions involving copperhead are shown below.
Left: a copperhead eater found by Simon Ekström. Right: a copperhead-to-glider converter found by James Pascua. Both use a claw with tail (click above to open LifeViewer) RLE: here Plaintext: here |
It can also be used in a switch engine channel to reduce the repeat time to 144 ticks.
