why are captive orca fins bent?
242102
All captive adult male orcas have collapsed dorsal fins, likely because they have no space in which to swim freely and are fed an unnatural diet of thawed dead fish. SeaWorld claims that this condition is common—however, in the wild, it rarely ever happens and is a sign of an injured or unhealthy orca.

Orcas are black and white for a reason; their coloring helps to camouflage them by obscuring their outline in the water.

Orcas are highly intelligent, social mammals. Largest of the dolphins, the orca, is a highly successful predator, feeding on fish, seals, and sometimes whales.

But it's not only orcas who suffer at the marine abusement park – several other species of animals are confined to filthy, cramped tanks and exploited in the name of entertainment, too. Orcas are actually a type of dolphin, and 41 of them have died at SeaWorld so far.

A upside-down swimming is a common problem in goldfish and the cause is a disorder of the swim bladder. This specialised organ enables a fish to modify its buoyancy so it can dive or surface according to its needs.

Orcas are most definitely not safe to swim with. A lot of people don't understand the dangers of swimming with orcas, in the wild or in captivity, they are extremely unpredictable. No marine facilities are allowed to condone marine biologists to swim with orcas in North America.

Male orcas are much larger and heavier than females, growing as long as 32 feet and weighing 11 tons, while females grow up to 28 feet in length but tip the scales at 7 tons. The size of the dorsal fin is also a strong indication of gender. ... The flippers of adult males are also longer and broader than those of females.

Pectoral fins originate behind the head and extend outwards. These fins are used for steering during swimming and help to provide the shark with lift. Pelvic fins are found near the claoca and are also stabilizers. In males they have a secondary function as they are modified into copulatory organs called claspers.

The swim bladder is a gas-filled sac that helps keep bony fish buoyant! They have paired pectoral and pelvic fins, and all but a few species have bones in their fins. They also have dorsal, anal, and caudal fins. Bony fish also have an operculum.

You should avoid keeping them with long-finned fish such as Sailfin Molly fish or Elephant Ear Guppies – your Danios will nip at the tail fins of these fish. This fin nipping behavior can be a sign that either, the tank is too small, or, the Zebra Danio shoal is too small.

It could cost a lot to repair if the damage was serious enough. This is the exact reason why tails are docked as well. The Doberman tail is particularly thinner and susceptible to painful breaking or damage just from every day wear/use. Docking the tail prevents later on serious injury or damage.

They also have long, lean, curved necks and black-tipped bills with a distinctive downward bend. Their bent bills allow them to feed on small organisms—plankton, tiny fish, fly larvae, and the like. In muddy flats or shallow water, they use their long legs and webbed feet to stir up the bottom.

Both water and fat are almost incompressible. To avoid the problem of pressure, many animals that live very deep in the ocean do not have any air spaces inside their bodies (e.g. the fish have oil-filled swim bladders or no swim bladders at all). This means the crushing pressure really doesn't affect them.

These markings disappear as they mature. Their needle-like teeth are highly adapted for impaling fish, their main prey. Their teeth are long, narrow, and very sharp with smooth edges, with one and on occasion two smaller cusplets on either side. Sand sharks have a large second dorsal fin.

If fish are swimming slowly or with clamped fins, gasping at the surface, listless, not eating, or if their gills are purplish rather than bright pink-red they are not getting enough oxygen. Check your water's pH, nitrates and ammonia levels.

Movement. Seahorses are poor swimmers. They rely on their dorsal fin beating at 30-70 times per second to propel it along. Pectoral fins either side of the head help with stability and steering.

Enhanced Strength: Gang Orca possesses the strength of a killer whale and has shown he is strong enough to overpower a mid-level Nomu. Enhanced Durability: Despite having an innate weakness to extreme heat, Gang Orca was able to endure being trapped inside a spiraling flame prison for several minutes.
