The ocellated icefish (Chionodraco rastrospinosus) is a fish of the family Channichthyidae. [3] [4] It lives in the cold waters off Antarctica and is known for having transparent haemoglobin-free blood. [5] [6] C. rastrospinosus live in the Southern Ocean up to a depth of 1 km. They are most commonly found on the seabed at 200–400 m.
Chionodraco icefishes are predatory, feeding on other fish species and on krill. They have a long post larval pelagic phase. [3] In common with many other channichthyid fishes, reproduction in Chionodraco hamatus involves laying eggs in a nest and parental guarding.
All icefish are believed to be piscivorous, but can also feed on krill. [10] Icefish are typically ambush predators; thus, they can survive long periods between feeding, and often consume fish up to 50% of their own body length. Maximum body lengths of 25–50 cm (9.8–19.7 in) have been recorded in these species.
Ocellated Icefish. On February 12, 2013, the ocellated icefish (Chionodraco rastrospinosus) spawned in captivity for the first time on record. About 500 eggs, each with a diameter of about 4.5 mm, were laid.
The ocellate soapfish has a body which is moderately elongate with a depth which is less than the length of the head. [8] The body is dull yellowish-brown body and it has similarly coloured fins with a single dark, ocellate (eye-like) spot on the gill cover and a dark brown spot on either side of the chin. [8]
The spiny icefish is native to the Southern Ocean where it occurs in a circum-Antarctic distribution, with the northernmost records from the South Orkney Islands. [5] It is a benthopelagic species which lives at depths of up to 800 m (2620 ft), [1] however, it is common in the shallower waters of the continental shelf, especially on banks less than 250 m (820 ft) deep.
The ocellated dragonet or scooter dragonet (Neosynchiropus ocellatus) is a species of tropical marine fish in the family Callionymidae. It is native to the southwest Pacific Ocean from southern Japan to the Marquesan Islands .
Takifugu ocellatus, [1] sometimes known as the ocellated puffer or the orange-saddle puffer, is a species of anadromous pufferfish in the family Tetraodontidae. It is native to China and Vietnam . Juveniles of the species occur in brackish and freshwater environments, but adults are marine.
