For the 31,420 species in the Class Actinopterygii (Ray-Finned Fishes), we average 66.73 observations each in our database; for the Grey Gurnard, we have 208 observations. Compared to other species in this Class, this species is somewhat common.
A two-sample t-test can be used to determine whether the trend in observations of the Grey Gurnard is the same as the trend in observations of Actinopterygii. Is this species just as common, as a proportion of all observations, as it once was? The answer is yes, changes in observation rate of this species do not significantly differ from changes in observation rate of its Class.

The family Triglidae belongs to the ClassActinopterygii (ray-finned fishes) and the Order Scorpaeniformes. It contains 14 genera and 100 species. It may be found in Marine and Brackish environments and is primarily Marine. Some members of this family are used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adultfish in this family is tetraodontiform. Compared with other fish, the activity level of this family tends to be normal. Members of this family have been dated back to the upper Eoceneepoch of the Tertiaryperiod.Etymology of this family name: Greek, trigla, -es = red mullet
Size/Age/Growth:
Males are commonly 30 cm (Total Length) in length when caught/marketed, but may be as large as 60 cm (Total Length).
Common on sandy grounds, sometimes on rocky bottoms, and also on mud between coastline to 140 mdepth. May be found at depths of 10 to 300 meters. Usually found at depths of 10 to 150 meters.
