The tripod fish or tripod spiderfish, Bathypterois grallator, is a deep-sea benthic fish in the family Ipnopidae found at lower latitudes. It is now relatively well known from photographs and submersible observations, and seems to prefer to perch on the ooze using very elongated fin rays in the tail and two pelvic fins to stand, facing upstream with the pectoral fins turned forward so the ...
The silverfish is a nocturnal insect typically 13–25 mm (0.5–1.0 in) long. [3] Its abdomen tapers at the end, giving it a fish-like appearance. [4] The newly hatched are whitish, but develop a greyish hue and metallic sheen as they get older. [5] It has two long cerci and one terminal filament at the tip of the abdomen between the cerci.
Bathypterois dubius [1]. Bathypterois is a genus of deepsea tripod fishes.They are a diverse genus that belong to the greater family Ipnopidae and order Aulopiformes.They are distinguished by having two elongated pelvic fins and an elongated caudal fin, which allow them to move and stand on the ocean floor, much like a tripod, hence the common name.

Researchers believe they've recorded potentially the first-ever sighting of an adult abyssal fish, Melanocetus johnsonii, in broad daylight.. Normally found at depths between 200 and 2,000 meters ...
Their movement has been described as "fish-like" as if they were swimming. Most extant species have a body length less than 2 centimetres (0.79 in) long, though Carboniferous fossils about 6 cm long are known. [5] Zygentoma have dorsiventrally flattened bodies, generally elongated or oval in outline. Their antennae are slender and
Anomalopidae (lanterneye fishes or flashlight fishes) are a family of fish distinguished by bioluminescent organs located underneath their eyes, for which they are named. These light organs contain luminous bacteria and can be "shut off" by the fish using either a dark lid or by being drawn into a pouch. They are used to communicate, attract ...
The six segments of the abdomen each bear a pair of pleopods, while the thoracic appendages are either walking legs or maxillipeds. The head segments bear various mouthparts and two pairs of antennae. The first antennae, or antennules, are held on a long flexible stalk, and are used for sensing the environment. The second antennae are the ...
They often have long filamentous antennae, though in male fishflies they are characteristically feathered. Ocelli are present; the fourth tarsal segment is cylinder-shaped. The four large wings are translucent, smoky grey, or mixed, and the anterior pair is slightly longer than the posterior one. Their aquatic larvae are used as fish bait and ...
