Colophon
The animal on the cover of Drupal for Designers is a butterfly blenny (blennius ocellaris). It is a small fish, only growing to approximately 8 inches in length. The butterfly blenny is characterized by a long, comb-shaped dorsal fin and tentacles around its nasal area.
The Blenniidae family is quite numerous and recognized by a long, tapering body and dorsal fin. However, blennies vary widely in appearance, behavior, and eating habits.
Butterfly blennies are nocturnal fish. They inhabit shallow water from Morocco to the English Channel, feeding on small invertebrates and mollusks. Blennies make their homes among seaweed and large rocks, often using castoff shells as homes and as places to keep their eggs safe. Sometimes, they have even been known to inhabit old cans. Blennies are protective of their eggs: the male watches over them constantly and refuses to leave them until they hatch.
