Breeder ID: AMPOCE-100509-WARCLI-009 Date posted: 10/3/2009

Identification: Amphiprion ocellaris (Cuvier, 1830)

Common name: Common Clownfish (this report describes Black and White Ocellaris)

Geographic origin: Indo-Pacific


Taxonomy: (after I.C.Z.N.)

Kingdom Animalia

Phylum Chordata Subphylum Vertebrata

Class Osteichthyes

Order Perciformes Superorder Teleostei

Family Pomacentridae

Genus Amphiprion

Species ocellaris (Cuvier, 1830)  


Description: Normally orange body (orange replaced by black in this spawning pair) with three distinct white body stripes (or bars ); the head stripe is anterior to the eye and continues down across the preoperculum. The body stripe extends from between the spinous (anterior) and soft-rayed portion of the dorsal through the body to the abdomen just in front of the anal fin with the center of the stripe “bulging” towards the head.
The tail stripe covers the caudal peduncle. The stripes have narrow black margins. The fins are rimmed in black just prior to a small non-pigmented edge. A. ocellaris is commonly confused with A. percula which is “shorter” in height (A. Percula is 3.1 – 3.3 in head-length compared to 2.1 – 2.9 head-length for A. ocellaris). Additionally A. ocellaris has 11 dorsal spines (rarely 10) compared to A. percula having 10 dorsal spines (rarely 9). Maximum size is listed by most sources at 90 mm – 95 mm, however, Burgess, 1988, lists 150 mm. Females are typically larger than the male.

Distribution is from the Indo-Malaysian Archipelago, Philippines, southward to northwestern Australia and northward to the Ryukyu Islands. The symbiotic relationship of clownfishes is well documented and this species is found with Heteractis magnifica (Qouy & Gaimard, 1833), Stichodactyla gigantea (Forsskål, 1775) and S. mertensii (Brandt, 1835).

Original description: Cuvier first described Amphiprion ocellaris in 1830 in Cuvier & Valenciennes 1830:399 in the Hist. Nat. Poiss. V.5 reference 999, from a specimen collected in Sumatra, Indonesia. Validated by Ida in Masuda et al., 1984 and Allen in 1991.

Synonomy:

Amphiprion melanurus, Cuvier in Cuvier & Valenciennes 1830:400 in Hist. Nat. Poiss. v. 5; ref.
999, From a single (Holotype ) specimen also collected in Sumatra, Indonesia. Synonym of
Amphiprion ocellaris Cuvier 1830 (Allen 1991:237 [ref. 19344]).

Amphiprion bicolor, Castelnau 1873:92 in Proc. Zool. Acclim. Soc. Victoria v. 2; ref. 758. From a single (Holotype) specimen collected near Darwin, Northern Terr., Synonym of Amphiprion ocellaris Cuvier 1830 (Allen 1991:237 [ref. 19344]).

Vernacular name: Common clownfish, Ocellaris clownfish, Anemone Demoiselle, False Clown Anemonefish and False percula clownfish (Black and White Ocellaris described in this report).

Word origin: Amphiprion is from the Greek roots amph, -i, -o, meaning around, on both sides; double, and -prion which means a saw. The genus ocellaris is confusing; the Latin root o, meaning an egg; cell, -a, -i, meaning a cell; or perhaps ocell, =us, meaning little eye and -ris meaning laughter (little laughing eye?). The synonym melanurus is composed of the Greek roots melan, -o, meaning black; and ur, =a, -o, meaning tail (thus black tail). The synonym bicolor means two colors (bi = two).
