Info
Cabillus caudimacula is a species found around Hawaii on sandy bottoms near reefs, making it a largely unknown goby.
Its habitats include sand fields at the seaward edge of the spur and groove habitat outside the barrier reef, adjacent to rubble and pavement.
COLOR IN LIFE – (from a photograph of a live specimen at Kahe Point, O'ahu).
The basic color of the head and body is white.
A prominent black triangle is visible on the side of the tail peduncle, extending to the base of the caudal fin, with the apex of the triangle pointing forward and the base extending to the rays and membranes.
A group of melanophores can be seen on the body below the pectoral fins.
There are three small black spots on the midline of the body, located below the second dorsal fin.
A dark spot is located at the top of the nape and at the top of the head behind the eyes.
An oblique black band extends over the eye and continues on the upper and lower jaw.
The pupil is black, the iris white.
The first dorsal fin is clear, except for a few black pigment spots at the base of the membrane behind the last spine.
The second dorsal fin is also clear, except for small black spots at the bases of elements three to five.
The tail, anal, chest and pelvic fins are completely clear.
Etymology:
The species name “cabillus” comes from the Dutch and means “ cod = Dorsch”, a dish made from chopped up cod. “caudimacula” is a compound adjective in Latin, ‘cauda’ for tail and ‘macula’ for spot, which refers to the conspicuous black spot at the rear end of the body and at the base of the tail fin.
Its habitats include sand fields at the seaward edge of the spur and groove habitat outside the barrier reef, adjacent to rubble and pavement.
