Once the whales were dead, the tide gradually washed them to shore. "They feed at this massive depth and they have no competition, so anything that disturbs them is really going to concern them.". It is not entirely random. "My own professional opinion is that it didn't initiate it.". Some deep-sea fish, like the orange roughy, live to be 175 years old, according to the book Sexuality in Fishes. Once the body comes to rest, biologists refer to this as a whale fall. What happens to whales when they die of old age in the ocean? Ten years later, a group of marine biologists came across another one, again by chance. In 2014 they reported that the fossils represented four separate mass strandings of baleen whales, which happened at intervals over 5 million years ago. A single whale carcass can support a whole community of small invertebrates, such as crabs and worms that feed on the oil-rich bones and tissues. Lonny Lundsten of the Monterey Bay Aquarium Research Institute in Moss Landing, California and his colleagues sank five carcasses and tracked them. It was the biggest stranding in the area in over a decade, according to local conservation teams. Surfacing too quickly could also give them the bends, in which bubbles of gas form in their blood due to the rapid changes in pressure.

And male killer whales can live to be 50 – 60 years old, but usually live until around their 30’s. For example, in the UK there was a 25% increase between 1990 and 2010, according to the UK Cetacean Strandings Investigation Programme. Once they were stuck in shallow water, the whales would tire quickly. r/teenagers is the biggest community forum run by teenagers for teenagers. Do they float, or sink to the bottom? Human activity-related causes of death like entanglement , ship strike , pollution , all pose very serious threats to cetaceans and combined cause hundreds of thousands of deaths per year.

For example, 14 humpback whales died and then stranded due to these toxins in Cape Cod, Massachusetts over a five-week period in 1987. They found that the species living on them became more diverse over the years, eventually including bone-eating worms, deep-sea crabs and multi-coloured pom-pom anemones (pictured below). Studies have revealed parasitism to be the leading cause of stranding in cetaceans. There are a number of ways that whales can meet the end of their lives. If there were blooms in the sea, the whales may have eaten poisonous algae, or eaten prey that had eaten the algae. Like Farewell Spit, something about this area prompted repeated strandings. ", Some coastlines get more strandings than others.

As you can see from this example a whales environment and social structure can be detrimental in determining its longevity. Pyenson says strandings of baleen whales were probably more frequent a few hundred years ago, and even more common in the more distant past.

But what happens next?

That's simply because marine life was much more abundant in the past than it is today.

As fascinating as the mysterious lives of cetaceans are, some of the most incredible biological processes begin after life ends. According to the final report into the stranding, "the information available does not permit definitive conclusions to be drawn".
