_____
Order Lophiiformes – anglerfishes
Spelling:
Lophiiformes. L,O,P,H,I,I,F,O,R,M,E,S.
Taxonomic Rank: Order
Key Characteristics: Modified dorsal spine as lure (illicium), large mouth, reduced pelvic fins

_____
Order Tetraodontiformes – puffers, boxfishes, triggerfishes
Spelling:
Tetraodontiformes. T,E,T,R,A,O,D,O,N,T,I,F,O,R,M,E,S.
Taxonomic Rank: Order
Key Characteristics: Fused jaw bones, reduced vertebrae, rigid body armor (in some), inflation behavior (in puffers)
Biological Context: Highly derived percomorphs. Exhibit unique defense strategies and feeding mechanisms. Includes reef-associated species with ecological and toxicological significance.
_____
Order Gobiiformes – gobies and sleepers
Spelling:
Gobiiformes. G,O,B,I,I,F,O,R,M,E,S.
Taxonomic Rank: Order
Key Characteristics: Small body size, fused pelvic fins forming suction disc, benthic lifestyle
Biological Context: One of the most species-rich vertebrate orders. Found in marine, freshwater, and brackish habitats. Important in reef ecology, symbiosis (e.g., shrimp-goby pairs), and microhabitat specialization.
______
Order Blenniiformes – blennies
Spelling:
Blenniiformes. B,L,E,N,N,I,I,F,O,R,M,E,S.
Taxonomic Rank: Order
Key Characteristics: Elongate body, comb-like teeth, reduced swim bladder, benthic behavior
Biological Context: Found in shallow marine habitats. Exhibit territoriality and cryptic coloration. Some species show parental care and amphibious behavior.
_____
Order Gobiesociformes – clingfishes
Spelling:
Gobiesociformes. G,O,B,I,E,S,O,C,I,F,O,R,M,E,S.
Taxonomic Rank: Order
Key Characteristics: Ventral suction disc formed from pelvic fins, small body size, scaleless skin
Biological Context: Specialized for adhering to rocks and corals in high-energy environments. Important for studying microhabitat specialization and adhesion biomechanics.
______
Order Labriformes – wrasses and parrotfishes
Spelling:
Labriformes. L,A,B,R,I,F,O,R,M,E,S.
Taxonomic Rank: Order
Key Characteristics: Protractile jaws, cycloid or ctenoid scales, swimming via pectoral fin sculling
Biological Context: Reef-associated fishes with diverse feeding strategies. Wrasses are cleaners and predators; parrotfishes graze algae and bioerode coral. Exhibit sex change and complex social structures.
_______
Order Perciformes – perch-like fishes
Spelling:
Perciformes. P,E,R,C,I,F,O,R,M,E,S.
Taxonomic Rank: Order
Key Characteristics: Two dorsal fins, thoracic pelvic fins, ctenoid scales, diverse body forms
Biological Context: Largest vertebrate order. Includes species from nearly every aquatic habitat. Highly variable morphology and ecology. Central to fisheries, reef ecology, and evolutionary studies.
