Richard Lawrence Pyle (born 24 March 1967) is a scuba diver and ichthyologist working on Hawaii.

[1][2] Pyle discovered the principle of "Pyle stops" when decompressing from many deep dives in search of new species of fish, and has identified hundreds of new species.

[1] In October 2015, he won second prize, an award of €5,000, in the GBIF Ebbe Nielsen Challenge, a Global Biodiversity Information Facility competition, for BioGUID.org, "a web service that crosslinks identifiers linked to data objects in the biodiversity realm".

[5] At that time, the site contained over one billion (1,000,000,000) identifiers.

[5] He has been honoured by having the twilight fangblenny (Petroscirtes pylei) named in his honor.
