Some female octopuses, like Octopus vulgaris, and certain species of Pacific salmon, such as Chinook salmon, die after giving birth due to intense energy expenditure during reproduction. However, these cases are exceptions. Most animals have evolved strategies for multiple reproductions and ensure their survival beyond the reproductive phase.
European glow worms are beetles that give birth to live young. The female lays eggs in suitable locations, like the ground or rotting vegetation. The hatched larvae feed on small insects. After molting, they become pupae and later hatch into adult beetles.
Labord's chameleons, found in Madagascar, are lizards renowned for their color-changing ability used for camouflage. Their lifespan is approximately four years, with reproduction occurring solely in their last year of life.
The Giant Pacific Octopus is an enormous marine creature inhabiting the Pacific Ocean along the coast of North America, Japan, and Korea. With a potential length of up to 16 feet and a weight of around 600 pounds, it is a formidable presence in the underwater world.
Cecropia moths, one of North America's largest moth species, boast an impressive six-inch wingspan. They derive their name from Cecrops, a mythical figure who was part man and part snake. These moths have a brief adult lifespan of about a week, while their larval stage can extend up to two years.
Ticks are tiny arachnids commonly found in forested areas. They latch onto the skin of animals and feed on their blood. These parasites have the ability to transmit diseases to their hosts, posing a potential threat to their health and well-being, sometimes leading to severe consequences or even death.
Praying mantises are insects known for their unique reproductive behavior. After a female mantis lays her eggs, she typically dies shortly thereafter. The eggs eventually hatch, and the young mantises must survive on their own. Through multiple molts, they gradually mature into adulthood. Once they reach maturity and mate, the cycle of life begins a new.
Longfin eels, found in New Zealand's rivers and lakes, can reach lengths of up to 2 meters and live for up to 50 years. Upon reaching maturity, they migrate back to their birthplace in freshwater to spawn. Following spawning, the female longfin eel dies.
Social spiders, unlike their solitary counterparts, live in large groups and work cooperatively to construct and maintain their webs. After mating and producing offspring, these spiders typically have a short lifespan and die soon thereafter.
Mayflies, short-lived insects, have a lifespan lasting only a few days. Adult females lay eggs near water, which hatch into larvae. The larvae grow and eventually emerge as adult mayflies. These adults have a brief existence, living for a few days solely for mating and reproduction before perishing.
Salmon, remarkable fish, exhibit an incredible upstream migration to spawn. After residing in the open ocean for several years, they return to the freshwater rivers and streams of their birth for reproduction. The female salmon digs a nest in the riverbed gravel to lay her eggs. Once fertilized, she covers them with more gravel, leaving them to incubate.
