The race of Cabira (one of Chilled's henchmen) is a race of fish-like humanoids from Dragon Ball; The Fish People from the radio broadcast Alexei Sayle and the Fish People; The Fishmen are a race of fish-like humans from the anime One Piece. They are modeled after different aquatic lifeforms. The Fishmen can breed with Giants to create Wotans.
When they swim, water flows into the mouth and across the gills. Because these sharks rely on this technique, they must keep swimming in order to respire. Bony fish use countercurrent flow to maximize the intake of oxygen that can diffuse through the gill. Countercurrent flow occurs when deoxygenated blood moves through the gill in one ...
H. littorale is armor-plated and dorso-ventrally compressed. [2] The fish will grow in length up to 24.0 centimetres (9.4 in) TL. [3]Males grow to a larger average and maximum size than females and, during the reproductive season, develop fat deposits in the pectoral fin and an elongated recurved pectoral spine that often assumes a reddish colour.
The majority of amphibians — except the order Gymnophiona , which are mainly terrestrial burrowers — have a fully aquatic larval form known as tadpoles, but those from the order Anura (frogs and toads) and some of the order Urodela (salamanders) will metamorphosize into lung-bearing and sometimes skin-breathing terrestrial adults, and most ...
Adult mummichogs tolerate low oxygen levels down to 1 mg/L, at which they resort to aquatic surface respiration (breathing in the surface layer of water, richer in oxygen because of contact with air) to survive. [30] [31] They can even survive for a few hours in moist air outside of water, breathing air directly. [32]
Mudskippers are any of the 23 extant species of amphibious fish from the subfamily Oxudercinae of the goby family Oxudercidae. [2] They are known for their unusual body shapes, preferences for semiaquatic habitats, limited terrestrial locomotion and jumping, and the ability to survive prolonged periods of time both in and out of water.
Most fish species spawn eggs that are fertilized externally, typically with the male inseminating the eggs after the female lays them. These eggs do not have a shell and would dry out in the air. Even air-breathing amphibians lay their eggs in water, or in protective foam as with the Coast foam-nest treefrog, Chiromantis xerampelina.
These fish are best kept with live or frozen feed and they easily outgrow the tank within eight to ten months. An aquarium with the minimum diameter of 6 by 3.5 feet (1.8 by 1.1 m) and 300 US gallons (1,100 L; 250 imp gal) is suggested as a bare minimum but 400–800 US gallons (1,500–3,000 L; 330–670 imp gal) is the best way to go.
