Tigrigobius
Tigrigobius is a genus of gobies, small fish in the family Gobiidae. The genus is currently recognized as having two species, both endemic to the eastern Pacific Ocean. These fish are commonly known as “tiger gobies” due to their distinctive tiger-like stripes. They are primarily found in intertidal and shallow subtidal zones, often inhabiting rocky reefs and tidepools.
Description
Tigrigobius species are characterized by their slender, elongated bodies, which can grow to a maximum length of around 10 cm (4 inches). They have a distinctive tiger-like pattern of dark brown or black stripes on a pale background. Their head is relatively large, and they have a prominent dorsal fin with two distinct sections. Their pectoral fins are rounded, and their caudal fin is slightly rounded or truncate. These gobies have small mouths with sharp teeth, adapted for feeding on small invertebrates.
Environment and Habitat
Tigrigobius species are typically found in intertidal and shallow subtidal zones along the eastern Pacific coast of North America. They are primarily associated with rocky reefs and tidepools, where they can find shelter and access to their prey. These gobies are adapted to tolerate a wide range of salinity and temperature fluctuations, which are common in their intertidal habitat.
Species
The genus Tigrigobius includes two recognized species:
- Tigrigobius redimiculus (Jordan & Gilbert, 1881) - This species is also known as the "tiger goby" or "striped goby". It is found along the coast of California and Baja California, Mexico.
- Tigrigobius calypso (Gilbert, 1904) - This species is also known as the "Calypso goby". It is found along the coast of southern California and Baja California, Mexico.
