Crocker's sea snake (Laticauda crockeri) is a species of venomous snake in the subfamily Laticaudinae of the family Elapidae.

The specific name, crockeri, is in honor of American railroad magnate Charles Templeton Crocker (1885-1948), who allowed the California Academy of Sciences to use his yacht, the Zaca, for scientific expeditions.

[3] L. crockeri is sexually dimorphic, with females growing to be longer and heavier than males.

[4] Maximum tail length is about 9 cm (3.5 in) in both sexes.

[4] L. crockeri is currently listed as "Vulnerable" by the International Union for Conservation of Nature (IUCN) due to the extremely limited distribution of the species.
