## What is the life span of an organism?

Life span, the period of time between the birth and death of an organism.

Which organism have the longest life span?

The quahog’s life-span is usually about 225 years. (Also see “405-Year-Old Clam Called Longest-Lived Animal.”) Some deep-sea fish, like the orange roughy, live to be 175 years old, according to the book Sexuality in Fishes. As far as mammals go, bowhead whales seem to have the most candles on their cake—over 200.

### What animals have life spans?

Greenland sharks are currently the vertebrate species with the longest known lifespan. An examination of 28 specimens in one study published in 2016 determined by radiocarbon dating that the oldest of the animals that they sampled had lived for about 392 ± 120 years (a minimum of 272 years and a maximum of 512 years).

What plant has the shortest lifespan?

If so, the one with the shortest lifespan is probably Arabidopsis (a mustard relative) with a seed-to-seed lifespan of about a month.

#### What is the maximum lifespan of a human?

Now researchers in Singapore, Russia, and the US have taken a different approach to estimate the maximum human lifespan. Using a computer model, they estimate that the limit of human lifespan is about 150 years. While most of us can expect to live to around 80, some people defy expectations and live to be over 100.

What living organism has the shortest lifespan?

Mayfly
Mayfly has the shortest lifespan on Earth — 24 hours or less. Greenland shark lives over 270 years. It’s the longest-living vertebrate.

## Which animal can live the longest?

The longest living mammal is the bowhead whale, which can live up to 200 years. Also known as the Arctic whale, this animal is big, and lives in cold waters so its metabolism is slow. The record age for a bowhead is 211 years.

What animal has 32 brains?

Leech
Leech has 32 brains. A leech’s internal structure is segregated into 32 separate segments, and each of these segments has its own brain. Leech is an annelid. They have segments.

### What is the shortest lifespan?

Mayfly has the shortest lifespan on Earth — 24 hours or less.

Which plant can live for many years?

A perennial plant or simply perennial is a plant that lives more than two years. The term (per- + -ennial, “through the years”) is often used to differentiate a plant from shorter-lived annuals and biennials.

#### Which dog has the shortest lifespan?

Top 10 Dog Breeds With The Shortest Lifespan

• Bullmastiff: 7-8 years.
• Great Dane: 7-8 years.
• Greater Swiss Mountain Dog: 6-8 years.
• Mastiff: 6-8 years.

• Bernese Mountain Dog: 5-7 years.

Can a person live 150 years?

While most of us can expect to live to around 80, some people defy expectations and live to be over 100. In places such as Okinawa, Japan and Sardinia, Italy, there are many centenarians. But a more recent study proposes that the limit to human life span is closer to 150.

## Which is true about the life span of an organism?

Life span – The period from birth to the natural death of an organism represents its life span. life spans of organisms are not necessarily correlated with their sizes. Whatever be the life span, death of every individual organism is a certainty, i.e., no individual is immortal, except single-celled organisms.

What’s the average life span of an animal?

12th Class Biology Origin of Life Life Span Organism Average life span Horse 60 years Elephant 65 years Eagle 90 years Man 60.4 years

### Which is the longest living organism on Earth?

A specific species of black coral, Leiopathes glaberrima, which is technically an animal and one of the longest-living organisms on the planet, grows at an intensely slow rate; a Hawaiian specimen was reported to have an age of 4,265 (±44) years.

How does reproduction affect the life span of an organism?

Figure 1.1 Approximate life spans of some organisms REPRODUCTION IN ORGANISMS Reproduction is defined as a biological process in which an organism gives rise to young ones (offspring) similar to itself. The offspring grow, mature and in turn produce new offspring. Thus, there is a cycle of birth, growth and death.
