In the original version (shown to the right), Jaws had an initial population of 150, which at the time was the smallest for any known pattern with superlinear growth. In November 1997, Gotts produced a 130-cell version of Jaws using some switch engine predecessors found by Paul Callahan. Jaws has since been superseded by smaller breeders such as mosquitoes, teeth, catacryst and metacatacryst.
Jaws consists of eight pairs of switch engines which produce a new block-laying switch engine (plus masses of junk) every 10752 generations. It is therefore an MMS breeder.
A copy of the 150-cell version of Jaws can be found in David Bell's Library of Life objects as life/grow/breed/b7.l.

gollark: Too bad.
gollark: I mean, yes, but actually no.
gollark: Randomish question which I think should go here: are there CAs which on small wrapping grids keep their population roughly around the starting population?
gollark: π
gollark: Interesting.
