Of reptiles there are many kinds: one snake (a Trigonocephalus
, or Cophias ), from the size of the poison channel in its fangs, must be very deadly.
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
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).
