Although at the surface the ocean can appear calm and quiet, in fact there is an enormous amount of life activity taking place, particularly at certain times of the year. Reproductive strategies abound in the ocean where we have fission, budding, eggs hatching externally, eggs hatching internally, live births, some marine animals are born in freshwater, some are born on land, etc. The marine environment creates unique challenges to the cycle of life, some that have been met with amazing adaptability.

Because of the complexity of marine life, research on marine life cycles is important because it helps document how marine organisms cope with abiotic factors in the marine environment such as ocean currents, tides, light, temperature, and the many other abiotic factors that influence life cycles. For example, habitat plays an important role in the life cycle of many marine organisms. Some select different habitats for different stages of life such as breeding, nesting, juvenile development, and maturity. Tracking migratory marine life through its life cycle is used to understand how a given species survives in its changing environment.

Sharks  seemingly are the only animals that never get sick and are immune to every known disease including cancer.

Seahorses have a single mate for life. Every morning, they come together, dance, change their color, twirl around with linked tails and then separate for the rest of the day.

While mating, seahorses utter musical sounds.

Beluga whales are called sea canaries.

Beluga whales have a large forehead, a sign of their high intelligence. Beluga whales are, in fact, the smartest animals on earth.

The in charge beluga is called a mermistress, she disciplines the young belugas, often eating those that are disobedient.

Beluga whales like to sing and are always making new sounds.

Walrus’ walk on their teeth.

Walrus’ change colour when they go in the water.

Sea cucumbers are echinoderms—like starfish and sea urchins. There are some 1,250 known species, and many of these animals are indeed shaped like soft-bodied cucumbers. All sea cucumbers are ocean dwellers, though some inhabit the shallows and others live in the deep ocean. They live on or near the ocean floor—sometimes partially buried beneath it.

Sea cucumbers feed on tiny particles like algae, minute aquatic animals, or waste materials, which they gather in with 8 to 30 tube feet that look like tentacles surrounding their mouths. The animals break down these particles into even smaller pieces, which become fodder for bacteria, and thus recycle them back into the ocean ecosystem. Earthworms perform a similar function in terrestrial ecosystems.

Sea cucumbers, particularly eggs and young larvae, are prey for fish and other marine animals. They are also enjoyed by humans, especially in Asia, and some species are farmed as delicacies.

When threatened, some sea cucumbers discharge sticky threads to ensnare their enemies. Others can mutilate their own bodies as a defense mechanism. They violently contract their muscles and jettison some of their internal organs out of their anus. The missing body parts are quickly regenerated.

Sea cucumbers can breed sexually or asexually. Sexual reproduction is more typical, but the process is not very intimate. The animals release both eggs and sperm into the water and fertilization occurs when they meet. There must be many individuals in a sea cucumber population for this reproductive method to be successful. Indeed, many parts of the deep ocean host large herds of these ancient animals, grazing on the microscopic bounty of marine waters.
With their expressive eyes, furry appearance and natural curiousity, seals have a wide appeal. Seals are divided into two families, the Phocidae, the earless or ‘true’ seals (e.g., harbor or common seals), and the Otariidae, the eared seals (e.g., fur seals and sea lions). This article contains facts about both earless and eared seals.
1. Seals are carnivores.
Seals are in the order Carnivora and suborder Pinnipedia, along with sea lions and walruses. “Pinnipedia” means “fin foot” or “winged foot” in Latin. Seals are divided into two families, the Phocidae, the earless or ‘true’ seals (e.g., harbor or common seals), and the Otariidae, the eared seals (e.g., fur seals and sea lions).
2. Seals evolved from land animals.
Seals are thought to have evolved from bear- or otter-like ancestors who lived on land.
3. Seals are mammals.
Seals do spend lots of time in the water, but they breed, give birth to live young and nurse their young on shore.
4. There are many kinds of seals.
There are 32 species of seals. The largest is the southern elephant seal, which can grow up to about 13 feet in length and more than 2 tons in weight. The smallest species is the Galapagos fur seal, which grows to up to about 4 feet long and 65 pounds.
5. Seals are distributed throughout the world.
Seals are found from polar to tropical waters. In the U.S., the most well-known (and watched) concentrations of seals are in California and New England.
6. Seals insulate themselves using a thick fur coat and layer of blubber.
Seals are insulated from cold water by their fur coat and by a thick layer of blubber. In polar environments, seals restrict blood flow to their skin surface to keep from releasing internal body heat to the ice. In warm environments, the reverse is true. Blood is sent toward the extremities, allowing heat to release into the environment and letting the seal cool its internal temperature.
7. Seals detect prey with their whiskers.
The diet of seals is varied depending on the species, but most eat primarily fish and squid. Seals find prey by detecting prey vibrations using their whiskers (vibrissae). For more information, view this article: Seals Use Whiskers for Hunting)
8. Seals can dive underwater deeply and for extended periods.
Seals can dive deeply and for extended periods (up to 2 hours for some species) because they have a higher concentration of hemoglobin in their blood and their large amounts of myoglobin in their muscles (both hemoglobin and myoglobin are oxygen-carrying compounds). Therefore, when diving or swimming, they can store oxygen in their blood and muscles and dive for longer periods than we can. Like cetaceans, they conserve oxygen when diving by restricting blood flow to only vital organs and slowing their heart rates by about 50-80%. In a study of northern elephant seals, the seal’s heart rate went from about 112 beats per minute at rest to 20-50 beats per minute when diving.
