Heteractis malu, also known as the malu anemone, delicate sea anemone [1] or white sand anemone, is a species of sea anemone in the family Stichodactylidae. [2]

Description

This anemone has stout, sparse tentacles, almost always under 40mm in length, usually tipped with magenta colouration. These tentacles vary in length, even among a single radial row. [1]

The column has a pale cream or yellow colouration, with patches of deep yellow or orange sometimes present. It remains buried in sediment up to the level of the oral disc. [1] The oral disc grows to a maximum diameter of 200 mm, is brown or purplish, possibly with a white, radial pattern. It may sometimes be bright green, but this is rare. [1]

This species is similar in appearance to Macrodactyla doreensis , Heteractis aurora , and Heteractis crispa . These species are also found burrowed into the sediment, and share the same red or yellow blotches. H. malu is primarily distinguished by its short sparse tentacles. [1]

Distribution

Heteractis malu occurs in scattered areas ranging from Japan in the north, to Australia in the south, east to the islands of Hawaii and west to Sumatra. [1]

The only anemonefish associated with this species is Clark's anemonefish (Amphiprion clarkii). [1] Sexually mature fish are rarely associated with H. malu, however the reason for this is unknown. [1] The relationship between anemonefish and their host sea anemones is highly nested in structure. The anemonefish is the active partner in establishing the interaction. [3] As the single hosted anemonefish, A. clarkii, [1] is the extreme generalist, it may be that H. malu is a marginal host tolerated only by the least selective fish and only when no other host is available.

Amphiprioninae Subfamily of fishes

Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild, they all form symbiotic mutualisms with sea anemones. Depending on species, anemonefish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 17 cm (6.7 in), while the smallest barely achieve 7–8 cm (2.8–3.1 in).

Clarks anemonefish Species of fish

Amphiprion clarkii, known commonly as Clark's anemonefish and yellowtail clownfish, is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes.

<i>Heteractis magnifica</i> Species of sea anemone

Heteractis magnifica, also known by the common names magnificent sea anemone or Ritteri anemone, is a species of sea anemone belonging to the Stichodactylidae family native to the Indo-Pacific area.

Orange skunk clownfish Species of fish

Amphiprion sandaracinos, also known as the orange skunk clownfish or orange anemonefish, is a species of anemonefish that is distinguished by its broad white stripe along the dorsal ridge. 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.

Sebae anemone Species of sea anemone

The sebae anemone, also known as leathery sea anemone, long tentacle anemone, or purple tip anemone, is a species of sea anemone belonging to the family Stichodactylidae and native to the Indo-Pacific area.

Bubble-tip anemone Species of sea anemone

Bubble-tip anemone is a species of sea anemone in the family Actiniidae. Like several anemone species, E. quadricolor can support several anemonefish species, and displays two growth types based on where they live in the water column, one of which gives it the common name, due to the bulbous tips on its tentacles.

Orange-fin anemonefish Species of fish

The orange-fin anemonefish is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes, found in the Western Pacific north of the Great Barrier Reef from the surface to 20 m, to include the Pacific Ocean between Queensland, Australia, and New Guinea to the Marshall and Tuamotus Islands. It can grow to 17 cm in length.

Saddleback clownfish Species of fish

Amphiprion polymnus, also known as the saddleback clownfish or yellowfin anemonefish, is a black and white species of anemonefish with a distinctive saddle. 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.

<i>Amphiprion akindynos</i> Species of fish

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. 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. The fish's natural diet includes zooplankton.

Red Sea clownfish Species of fish

Amphiprion bicinctus, meaning "both sawlike with two stripes," commonly known as the Red Sea or two-bandedanemonefish is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes. Like other species of the genus, the fish feeds on algae and zooplankton in the wild.

Pink skunk clownfish Species of fish

Amphiprion perideraion also known as the pink skunk clownfish or pink anemonefish, is a species of anemonefish from the skunk complex that is widespread from northern Australia through the Malay Archipelago and Melanesia. Like all anemonefishes, it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host. 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 nonbreeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male changes to female if the sole breeding female dies, with the largest nonbreeder becoming the breeding male.

The three-band anemonefish is a species of anemonefish endemic to the Marshall Islands in the western part of the Pacific Ocean. Like all anemonefishes, it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of its host. 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 nonbreeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male changes to female if the sole breeding female dies, with the largest nonbreeder becoming the breeding male.

<i>Stichodactyla mertensii</i> Species of sea anemone

Stichodactyla mertensii, commonly known as Mertens' carpet sea anemone, is a species of sea anemones in the family Stichodactylidae.

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.
