9 Geoduck

Holding the Geoduck in two arms.

The geoduck is the most important burrowing bivalve. It is likely one of the longest dwelling animals on the earth that belongs to the household Hiatellidae.

The geoducks can attain their full dimension at about 15 years outdated. These filter feeders primarily eat phytoplankton, pelagic crustaceans, and fish larvae. Apart from, the predators of those aquatic species embody sea otters, dogfish, and starfish. They’ve a really lengthy lifespan, with particular person species identified to achieve ages over 160 years outdated. Apart from people, the best risk to those geoducks comes from crabs, starfish, flatfish, and moon snails.

3 Ocean quahog

ocean quahog
Meet the world’s one of many oldest dwelling animals, the ocean quahog.

Ocean quahog is edible clam species that belongs to the Arcticidae household. They signify commercially exploited longest dwelling species of a bivalve mollusk. Some collected these oldest dwelling clams can attain an age of greater than 400 years.

2 Greenland Shark

greenland Shark
Greenland Shark encountered through the Northeast U.S. Canyons Expedition.

Like all sharks, the Greenland shark belongs to the household Somniosidae and may attain about 200 years, making it the longest-living animal. Different names of the species are the gurry shark, gray shark. Though one specimen lived as many as 512 years, making it the longest dwelling vertebrate on the earth.

1 Glass Sponges

glass sponges
A golden crab contemplates a spectacular glass sponge.

Glass sponges are animals within the class Hexactinellida generally discovered within the deep ocean, native to the East China Sea and the Southern Ocean. This deep-sea sponge has a spun glass look and has skeletons of siliceous spicules with a particular triaxonic symmetry often known as Hexactinellid sponges.

They inhabit nearly all of the world’s oceans, however these longest dwelling animals are frequent in Antarctic and Northern Pacific waters. These basic glass-like particles of their tissues, often known as spicules, are made up of silica. Their skeleton entraps a selected shrimp species inside for all times and supplies protection towards many predators and numerous chemical substances.

The glass sponges eat small micro organism and plankton from the encircling water. Intricate skeletons of those sponges provide safety for a lot of different animals. Extra-or-less cup-shaped, these sponges have a symmetrical physique with a big central cavity. Some species of those sponges produce spicules that fuse to construct reefs or bioherms. 

We will discover the colour of those bioherms pale in colour, starting from white to orange. Euplectella, one of many sponge species, is called the Venus flower basket as a result of they construct their skeleton that entraps shrimp inside. This sponge homes double shrimp-like small Stenopodidea, a male and a feminine, who lives contained in the sponge.

The crustaceans breed, and when its tiny offspring, it escapes to discover a new Venus flower basket of its personal. It could actually survive for greater than 10000 years. Thus, it wins the title of the world’s longest-living animals. 

  • Scientific Identify: Hexactinellida
  • Common grownup size:32 cm
