Originally rendered with Rapidographs on vellum, I just finished redrawing this in Illustrator 8; with tiny tweaks in Photoshop 7. The main figure has the tail of a moray eel rather than that of a fish. Being rather literal minded, I've always called the creatures "peels".

Due to a request, or not, here is some of the background information on these creatures that I researched back in *ahem* 1968-1969:

The Morays (MURAENIDAE)
Small gill opening, never a trace of a pectoral fin, dorsal and anal high or low, abundant in coral reefs in tropics, five feet or more; plain colored, mottled or more boldly patterned

Moray Peels:
MURAENIDAE HOMO SAPIENS
Found in large population groups in tropical seas.
Cities built into (carved out of) the great tropical reefs.
Average length: Male 5'-6'; Average length: female 4'-5'
Live in family groups, IE : father, mother & offspring (2-3)
Offspring are born live; gestation period similar to that of Terciops Truncatus.
They are nursed by the mother and fed by both parents throughout a period of total dependency lasting nearly 12 months.
They are then taught to care for themselves.
This training period lasts through adolescence to adulthood, about 30 years.
The young are then encouraged to mate and establish their own homesite.
Lineage traced paternally
Inheritance rights traced maternally
No dominant religion

Additional notation:
Webbed fingers would aid in swimming
Would form friendships and possible working partnerships with Terciops Truncatus
