Dead Sea-Monkeys generally sink to the bottom of their tank and begin to decompose. If a Sea-Monkey is not moving at the bottom of the tank, the creature is probably dead. Dead Sea-Monkeys change color from their normal translucent to black as they decompose.

"No animal lives forever, but these red sea urchins appear to be practically immortal," said Thomas Ebert, a marine zoologist at OSU. "They can die from attacks by predators, specific diseases or being harvested by fishermen. But even then they show very few signs of age.

Generally, they are not reef safe. The shrimp, starfish, and any clean up crew (snails/hermit crabs) will become food. It will probably pick on the angel too. Also, juvenile triggers do not fare well in aquariums and 90 gal is small for this fish.

The tiny vaquita porpoise will likely go extinct in the next few years, as less than 30 are left in the world. Discovered in 1958, the vaquita is the world's rarest marine mammal and could go extinct any day, according to the World Wildlife Foundation.

However, despite seeming common, they are actually Endangered (last assessed for the IUCN Red List in 2014). The Galápagos sea lion population declined by 60-65% from 1978 to 2001, and since then there has been no evidence of either decline or increase.

Koalas are considered vulnerable to extinction—just a step above endangered—and reports indicate that between 350 and a thousand koalas have been found dead so far in fire-devastated zones of northern New South Wales. But, experts say, we are not looking at the death of a species—yet.

Sea-Monkeys are a hybrid breed of brine shrimp called Artemia NYOS invented in 1957 by Harold von Braunhut. ... Pour the dust (which is actually brine shrimp eggs) in a tank of purified water, and the Sea-Monkeys spring to life. They grow steadily over the next few weeks, feeding on a diet of yeast and spirulina.

In my opinion there is no doubt that marine mammals should NOT be held in captivity. ... Many tanks have water full of chemicals and bacteria; this results in blindness and many skin problems in dolphins and other marine mammals. Marine mammals in captivity die from pneumonia, ulcers and other stress-related diseases.

Some affected whale populations are set to die out within a generation. The PCBs that whales, dolphins and porpoises absorb from their food end up being stored mainly in their fatty tissue (blubber). The levels of PCBs in an animal's blubber will build up over time as it consumes more and more contaminated fish.

Fish, seabirds, sea turtles, and marine mammals can become entangled in or ingest plastic debris, causing suffocation, starvation, and drowning. ... A recent study found that sea turtles that ingest just 14 pieces of plastic have an increased risk of death.

Parrotlets are near and dear to my heart. I do not believe they can die from loneliness. So don't beat yourself up in to thinking you were the reason your bird died. Birds have survival instinct and they are notorious at masking illness, and some die suddenly without warning.

Populations of short-nosed sea snakes are declining at rates of around 90 per cent; however, the demise of the species has not been attributed to one particular cause. Global warming has certainly affected the species' habitat, with coral bleaching occurring in reefs due to the warming of the ocean.

Hold the sand dollar gently in the palm of your hand and observe the spines. If they are moving, it is still alive. The animals lose these spines soon after they die. The dead sand dollar on the left has started to fade.

Like female seahorses, female Sea-Monkeys can fertilize their own eggs, a process called parthenogenesis. Even though some of your pets will become stuck together for prolonged periods, females don't have to mate to become pregnant. Females develop a sac in the front when they're pregnant.

There are none in captivity. Unlike their close relatives, beluga whales, narwhals do not thrive in captivity. In the '60s and '70s, several attempts at capturing and keeping narwhals resulted in all of the animals dying within several months. In fact, all narwhals kept in captivity have died.
