Characteristics of anemonefish

Clownfish or anemonefish are fishes that, in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see Amphiprioninae § Symbiosis and mutualism. The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators and parasites. [3] Clownfish are small-sized, 10–18 cm (3.9–7.1 in), and depending on species, they are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. Color variations occur between species, most commonly according to distribution, but also based on sex, age, and host anemone. Clownfish are found in warmer waters of the Indian and Pacific Oceans and the Red Sea in sheltered reefs or in shallow lagoons.

In a group of clownfish, a strict dominance hierarchy exists. The largest and most aggressive fish is female and is found at the top. Only two clownfish, a male and a female, in a group reproduce through external fertilization. Clownfish are sequential hermaphrodites, meaning they develop into males first, and when they mature, become females.

Description

Adults are a dark-brown to black color with two white bars with black edging encircling the body. The caudal fin is white with other fins orange. [4] They have 10-11 dorsal spines, two anal spines, 15-17 dorsal soft rays, and 15-17 anal soft rays. [5] They reach a maximum length of 14 cm (5+12 in). [4]


Similar species

Allard's anemonefish is almost identical to A. chrysopterus (orange-fin anemonefish) and are distinguished by their geographic location. Allard's anemonefish is similar to the nearby A. latifasciatus (Madagascar anemonefish), but A. latifasciatus has a forked, yellow caudal fin. [4]

Distribution and habitat

Allard's anemonefish is found in east Africa between Kenya and Durban. [4] and east to the Seychelles and Mascarene Islands. [1] They are usually found near to or within the tentacles of their host anemones.

Host anemones

Allard's anemonefish is associated with these species of anemones: [4]

Etymology

The specific name and the common name honour the aquarist and marine collector Jacques Allard who gave support to the author, Wolfgang Klausewitz's visit to East Africa and who supplied him with many specimens. [6]

Amphiprion melanopus, also known as the cinnamon clownfish, fire clownfish, red and black anemonefish, black-backed anemonefish or dusky anemonefish is a widely distributed anemonefish chiefly found in the western and southern parts of the Pacific Ocean.. The species scientific name 'melanopus' is Greek, meaning black feet in reference to the black pelvic fins. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict sized based dominance hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male will change to female if the sole breeding female dies, with the largest non-breeder becomes the breeding male.

Amphiprion akindynos, the Barrier Reef anemonefish, is a species of anemonefish that is principally found in the Great Barrier Reef of Australia, but also in nearby locations in the Western Pacific. The species name 'akindynos' is Greek, meaning 'safe' or 'without danger' in reference to the safety afforded amongst the tentacles of its host anemone. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict size-based dominance hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends.

Stichodactyla mertensii, commonly known as Mertens' carpet sea anemone, is a species of sea anemones in the family Stichodactylidae. It is regarded as the largest sea anemone with a diameter of over 1 m (3.3 ft), the next largest being Heteractis magnifica, which has longer tentacles. This species has an oral disc that can be described as more ovoid than circular that contours to the surrounding substrate and is attached to the substrate by adhesive verrucae, which are wart-like projections. Its blunt or pointed tentacles are uniformly shaped, and are only about 1–2 centimetres (0.39–0.79 in) long. It contains obligate symbiotic zooxanthellae, and is a host to around half the species of anemonefish and one damselfish, Dascyllus trimaculatus.
