Population Analysis

  • For the 31,420 species in the Class Actinopterygii (Ray-Finned Fishes), we average 66.73 observations each in our database; for the Blackmouth Goosefish, we have 247 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 Blackmouth Goosefish 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 no, changes in observation rate of this species significantly differ from changes in observation rate of its Class. (t=6.591, p<0.001)
  • How do observation rates of the Blackmouth Goosefish differ from those of Actinopterygii? To answer this, we examined the percentage of observerations for Actinopterygii that were observations of the Blackmouth Goosefish each year. We then correlated this percentage with observation year. If observations of the Blackmouth Goosefish are becoming more common relative to other species of Actinopterygii, the correlation should be positive, but if it is becoming less common, the correlation should be negative. In fact, the correlation is negative (r=-.29), with a negative slope (m = -.001), suggesting that the Blackmouth Goosefish may be in decline relative to other species of Actinopterygii. This correlation is statistically significant. (F = 17.09, p<.05)
  • The scatter chart to the right shows the percentage of all observations for Actinopterygii each year that were observations of the Blackmouth Goosefish.

Physical Description

[ Back to top ]

Family Lophiidae:

Distribution: Arctic, Atlantic (including the Mediterranean Sea), Indian and Pacific. Head extremely big, wide, and depressed (except Sladenia with rounded head). Well developed teeth. Lower jaw and sides of head and flanks fringed with small flaps. Pectoral fin 13-28 rays. Second dorsal fin 8-12 soft rays. Anal fin 6-10 rays. Vertebrae 18 or 19, in Lophius 26-31. Equipped with a movable rodlike structure above mouth, tipped with a flap of flesh resembling a flag apparently for luring prey. Mouth large. Maximum length 1.2 m.

The family Lophiidae belongs to the Class Actinopterygii (ray-finned fishes) and the Order Lophiiformes. It contains 4 genera and 25 species. It may be found in Marine environments and is primarily Marine. Members of this family are not used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adult fish in this family is subcarangiform. Compared with other fish, the activity level of this family tends to be sluggish. Members of this family have been dated back to the middle Eocene epoch of the Tertiary period. Etymology of this family name: Greek, lophos = crest
