what help fish regulate how close they swim to the bottom
water pressure that the fish can endure
The bottom fin on a fish acts like a keel on a boat. It helps keep the fish right side up in the water.
Fish and reptiles both regulate their body temperature behaviorally by going to areas where the temperature fits their biochemical needs, eg. sunning on rocks to raise temperature, etc. Some fish and reptiles also hibernate when temperatures get too cold.
my fish also does that. Is your fish a male or female? If it is a female it is probably pregnant. Hope that helps!
Thiamine (B1)
they sherwim to the bottom of the lake or sea close one eye while the other watches for preditors.
No, the Swai Fish is not a bottom feeder fish, but they do have a vegetarian diet.
Most fish can't regulate their body temperature and will simply be (very close to) the temperature of the surrounding water. Some sharks can maintain an internal temperature a little higher than ambient water temperature.
The pelvic fin is in the bottom; toward the front side of the middle. The pectoral fin is on the bottom, in the front. The pectoral fin helps control the direction the perch moves. The pelvic fin also controls the direction it moves. The anal fin is in the bottom back side and helps the fish balance. The dorsal fins are on top, one in the middle one it the back and stabalize the fish and aid in sharp turns. The caudal fin, or the tail, is in the back and helps to propel the fish through the water.
This just simply means that the fish are bottom dwellers.
Being the fastest fish, it is probably technically endothermic, like its close relative the swordfish, and several very fast, carnivorous fish and sharks. Many similar fish and sharks can at least regulate the temperature of their brain and eyes. Being warmer improves nervous system and muscular performance, and helps fish swim faster and hunt more effectively. But this is obviously not the same as being "warm-blooded", which is why biologists don't like to use two overly-broad categories.
they eay fish and if they can remains of a dead animal.
