Which is the largest alga on earth?
Biologists used the world’s largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants.
It is a single cell that can grow to a length of six to twelve inches.
What is the fastest growing seaweed?
Fastest growing seaweed
- Giant kelp (Macrocystis pyrifera) – 61 cm (24 in.) per day, northeastern Pacific. Although giant kelp plants are perennial, each frond survives for about 6-9 months.
- Bull kelp (Nereocystis leutkeana) – 15 cm (6 in.) per day, northeastern Pacific.
- Caulerpa taxifolia, a.k.a. Killer weed – 8 cm (3 in.)
What’s the fastest growing fish in the ocean?
Mahi Mahi, sometimes known as Dorado or Dolphin, are some of the fastest growing fish in the ocean. Mahi Mahi can spawn every two to three days at the early age of four to five months old.
What do macrocystis pyrifera eat?
Sea otters play a particularly important role in the health or the bay’s kelp forests; without them, sea urchins—which normally eat pieces of kelp that fall to the seafloor—will feed on the stipes of giant kelp plants and can completely destroy a kelp bed.
Which is largest cell?
The largest cells found in nature are ostrich eggs. Before fertilization, the entire interior of the egg consists of a single cell, which can weigh up to 5 pounds. The largest single-celled organism is an animal called Syringammina fragilissima, which can grow to a width of 4 inches.
What is the longest cell?
The longest cells in the human body are neurons. Neurons are cells within the nervous system and carry messages throughout the body. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot.
What is the largest seaweed?

Which fish grows the fastest?
Several species of edible fish can be successfully grown in freshwater ponds. The fastest growing of these are catfish, tilapia and carp.
What is the fastest reproducing fish?
The Easiest Freshwater Fish to Breed in an Aquarium
- Platies. Another livebearer, platies are nearly as easy as guppies to breed.

- Kribensis Cichlids.
- Zebra Danios.
Do people eat dolphin?
Dolphin meat is high in mercury, and may pose a health danger to humans when consumed. Ringed seals were once the main food staple for the Inuit.
How long do mahi mahi live?
They are a relatively short lived species, with a life span of only four or five years. Mahi-mahi are among the fastest growing fish, with a minimum population doubling time under 15 months. This makes them resilient to fishing pressure. However, their current vulnerability is moderate to high.
Which is the largest of all habitat?
The oceans cover 71% of the surface of the Earth, so seafloor provides the largest area for those species that move about on or are rooted to our planet’s surface – a reasonable justification for the “largest habitat on Earth”.
What eats kelp in the ocean?
Many species of fish and marine mammals inhabit kelp forests for protection and food. Sea urchins will often completely remove kelp plants by eating through their holdfasts. Other invertebrates found in kelp forests are sea stars, anemones, crabs, and jellyfish.
What animals eat coral?
When corals are babies floating in the plankton, they can be eaten by many animals. They are less tasty once they settle down and secrete a skeleton, but some fish, worms, snails and sea stars prey on adult corals. Crown-of-thorns sea stars are particularly voracious predators in many parts of the Pacific Ocean.
