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 ...
Digging deep burrows in soft sediments allows the fish to thermoregulate, [14] avoid marine predators during the high tide when the fish and burrow are submerged, [15] and lay their eggs. [16] When the burrow is submerged, several mudskipper species maintain an air pocket inside it, which allows them to breathe in conditions of very low oxygen ...
The sauger (Sander canadensis) is a freshwater perciform fish of the family Percidae that resembles its close relative, the walleye. The species is a member of the largest vertebrate order, the Perciformes. [3] It is the most migratory percid species in North America. [4]
Filefish spawn at bottom sites prepared and guarded by the males; both he and the female may guard the brood, or the male alone, depending on the species. The young filefish are pelagic; that is, they frequent open water. Sargassum provides a safe retreat for

These fish can rapidly change appearance to a high contrast color pattern with a much darker background and many light colored spots [2] With a maximum length of around 18 inches, they are smaller than the scrawled filefish which is also found in their range. The American whitespotted filefish is often seen in pairs.
The result is a spiny ball that is up to 3-4 times the resting volume of the fish, making them not easily ingested by their predators. [9] The spinues defend Arothron meleagris by deterring predation attempts, reducing capture success or making it difficult for the predator to ingest the fish. [10]
