I need to combine each of the folowing sentences and improve them( clarity and interest). English is not my first language,i am having harder times understanding this.

1. Every so often, a large group of wales or dolphins will throw itself upon shore. The whales strand themselves for no apparent reason.

2. Pilot whales are one species of marine mammal that frequently strand as a group. White-sided dolphins and false killer whales are two others.

3. All three species travel in groups. They are highly social.

4. Humans sometimes manage to discourage whales from running around. Then the animals simply try again later.

5. Individual mammals who beach themselves are often sick. Groups that run around are usually healthy.

6. Stranding almost invariably ends in daeth for these mammals. Why do they do it?

Thanks for help!

1. Every so often, a large group of wales or dolphins will throw itself upon shore. The whales strand themselves for no apparent reason.

Every so often, a large group of whales or dolphins will strand themselves upon shore for no apparent reason.

As you can see, the object is to make one sentence out of two sentences. I also took out a few words to make the sentence easier to understand.

Please try the other sentences yourself. Doing this exercise is a good way of improving your English.

We'll be happy to comment on your answers.

Pilot whales are one species of marine mammal that frequently strand as a group. White-sided dolphins and false killer whales are two others. I am not sure on this one..

These three species are highly social and they travel in groups.

After human manage to discourage whales from running around,they simply try again later.

Individual mammals who beach themselves are often sick, however groups that run around are usually healthy.

Stranding almost invariably ends in daeth for these mammals. Why do they do it? I don't know this one..

Pilot whales are one species of marine mammal that frequently strand as a group. White-sided dolphins and false killer whales are two others. I am not sure on this one.

Make this all one sentence. How can you do this?

These three species are highly social and they travel in groups.
Good.

After human manage to discourage whales from running around,they simply try again later.
Use "humans" and clarify "they." (That is, who are "they"? Humans or whales?

Individual mammals who beach themselves are often sick, however groups that run around are usually healthy.
Not bad, but put a semicolon (;) after "sick" and a comma after "however."

Stranding almost invariably ends in daeth for these mammals. Why do they do it? I don't know this one..
Here's a suggestion: It's hard to understand why whales strand themselves when it almost invariably ends in death for them.

P.S. Here is an interesting site offering a reason why thos mammals strand themselves:

1. Every so often, a large group of whales or dolphins will purposefully beach themselves on the shore, seemingly without any reason. This intriguing behavior of voluntarily stranding remains a mystery.

Explanation: To improve clarity and interest in the sentence, we can mention that the beaching is intentional. This can capture the reader's attention as they wonder why these marine creatures choose to strand themselves.

2. Pilot whales, white-sided dolphins, and false killer whales are three distinct species of marine mammals that often strand together as a cohesive group. This collective behavior adds to their uniqueness and raises questions about their social dynamics.

Explanation: By specifying that there are three different species involved, we emphasize the diversity within the phenomenon of stranding. Additionally, highlighting the cohesive nature of these groups adds to the interest by creating curiosity about their social interactions.

3. All three species - pilot whales, white-sided dolphins, and false killer whales - exhibit highly social behavior, preferring to travel in close-knit groups. This sociable nature adds an intriguing aspect to their stranding behavior.

Explanation: By emphasizing the social behavior of these species, we create a link between their tendency to strand and their desire to stay together. This adds depth to the explanation and makes it more interesting for the reader.

4. In certain instances, humans have been successful in deterring whales from repeatedly beaching themselves, but often, these determined animals will persist and make subsequent attempts at another time.

Explanation: By clarifying that humans can sometimes discourage whales from beaching themselves, we show that there are efforts to prevent this behavior. However, we also mention the persistent nature of these animals, making it more intriguing for the reader.

5. Individual mammals that find themselves stranded on the beach are often sick or injured, usually indicating an underlying health issue. However, when groups of marine mammals become stranded, it is typically a sign of overall good health within the group.

Explanation: By explaining the difference between stranded individuals and groups, we provide clarity on the varying health conditions. This adds interest as it shows that healthy groups are more likely to run around on the beach, contrary to the assumption that stranded animals are always sick.

6. Unfortunately, stranding events almost always result in death for these mammals, leaving us with the question: Why do they engage in this behavior that seems to have such dire consequences?

Explanation: By expressing the tragic outcome of stranding events, we evoke a sense of concern and intrigue. Additionally, by posing the question of why these mammals persist in such behavior, we engage the reader in contemplating the unknown motivations behind their actions.
