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 purpose of using RNA FISH is to detect target mRNA transcripts in cells, tissue sections, or even whole-mounts. [10] The process is done in 3 main procedures: tissue preparation (pre-hybridization), hybridization, and washing (post-hybridization). The tissue preparation starts by collecting the appropriate tissue sections to perform RNA FISH.
Fish with low inbreeding showed almost twice the aggressive pursuit in defending territory than fish with medium inbreeding, and furthermore had a higher specific growth rate. A significant effect of inbreeding depression on juvenile survival was also found, but only in high-density competitive environments, suggesting that intra-specific ...
Reproduction mount of a rhinoceros made of fiberglass. Some methods of creating a trophy mount do not involve preserving the actual body of the animal. Instead, detailed photos and measurements are taken of the animal so a taxidermist can create an exact replica in resin or fiberglass that can be displayed in place of the real animal. No ...
The swimming movements of these fish mainly consist of short, dart-like movements. [7] Their body coloration varies from warm brown to gray with a blotchy appearance. [8] Male sarcastic fringeheads are distinguished by their extremely wide mouth gape, which, when open, may be as much as four times its size when closed.

The gills of most teleost fish help to eliminate ammonia from the body, and fish live surrounded by water, but most still have a distinct bladder for storing waste fluid. The urinary bladder of teleosts is permeable to water, though this is less true for freshwater dwelling species than saltwater species.
The term "mackerel" is also used as a modifier in the common names of other fish, sometimes indicating the fish has vertical stripes similar to a scombroid mackerel: Mackerel icefish—Champsocephalus gunnari; Mackerel pike—Cololabis saira; Mackerel scad—Decapterus macarellus; Mackerel shark—several species; Shortfin mako shark—Isurus ...
