The climate of Hawaii is typical for a tropical area, although temperatures and humidity tend to be a bit less extreme than other tropical locales due to the constant trade winds blowing from the east.
The surrounding waters are affected by effluents generated and released from the islands themselves. Floating plastic garbage is a problem, and refuse from the Great Pacific Garbage Patch affects its beaches. Other pressures on Hawaii's fish population are its fishing industries and whaling[3] until IWC's moratorium in 1986.[4] In the last century, some commercially fished stocks have decreased by 80–85%.[5]
Due to its isolation, very few native freshwater fish species are found in Hawaii, and none are entirely restricted to freshwater (all are either anadromous, or also found in brackish and marine water in their adult stage).
An orangeband surgeonfish, a light grey fish with a dark grey back half, an orange stripe running from just below the eye past the ventral fins, and stopping just before the fish's dorsal fin. This fish has a very heavily lyre-shaped tail.
An Achilles tang, a black, lyre-tailed fish with an orange spot just before the caudal peduncle, black dorsal and anal fins with an orange stripe marking the boundary between fin and body. The tail is orange and white.
Dussumier's surgeon, a grey fish with a blue lyre-tail and a white spot on the caudal peduncle.
A blue striped snapper, a neon-green fish with four horizontal neon blue stripes running the length of its body.
A parrotfish is a large, dark blue fish with a light blue underbelly and a protruding forehead.
A cardinal fish, a brown fish with three vertical black stripes, black outlining on the caudal fin and caudal peduncle, and covered in white spots.
