Of reptiles there are many kinds: one snake (a
Trigonocephalus, or Cophias [18]), from the size of the poison channel in its fangs, must be very deadly.
Tridentiger
trigonocephalus and Acanthogobiusflavimanus, in southern California.
The development of stylohyal (a segment in the hyoidean arch) and its relation to columella auris and quadrate were estimated in Lacertilia (Parker, 1879), in Vipera bervus (Moller, 1905), in
Trigonocephalus (Okajima, 1915), In Leptodeira hotamboia (Brock, 1929), in lizard (De Beer, 1937).
Five most commonly observed fish species in the ARs were black rockfish (Sebastes inermis), jack mackerel (Trachurus japonicus), bambooleaf wrasse (Pseudolabrus sieboldi), chameleon goby (Tridentiger
trigonocephalus) and whitespotted pigmy filefish (Rudarius ercodes) (Fig.
Descripcion d'une nouvelle espece du genre Trigonocephale (
Trigonocephalus lansbergii).
Bacque's (1906) original description of
Trigonocephalus scolecomorphus suggests that the color pattern is similar to that of L.
The initial putative spread of Chameleon Goby, Tridentiger
trigonocephalus, into the low salinity Delta region of San Francisco Bay was due to the arrival and spread of a second, very similar brackish water species, the Shimofuri Goby, Tridentiger bifasicatus (Matern and Fleming 1995), described in Japan by Akihito and Sakamoto (1989).
The yellowfin goby (Acanthogobius flavimanus) was well represented in the samples (n = 34) while a single specimen of the chameleon goby (Tridentiger
trigonocephalus) was captured in the eelgrass bed in the South-Central Ecoregion (Station 3).
