1. The smallest sea crab - pea crab
The pea crab is a small crab that lives in shallow seas. Measuring only 3.8–4.2 millimeters long, it's about the size of a grain of rice. It can be called the dwarf of crabs. It is the smallest crab in the world. It also resembles a red bean, hence its name.
2. The heaviest sea crab – Australian king crab
The Australian king crab is the heaviest crab in the world. Its scientific name is giant king crab. It has long lived on the shore of the Bass Strait in Australia. The heaviest individual weighed more than 72 kilograms. It is also the largest known crab in the world. Its shell alone is almost the size of a washbasin. When the crab legs are fully extended, the length reaches 1.5 meters and the width is almost the size of an adult's outstretched arms.
3. The longest jellyfish – Arctic jellyfish
The Arctic lion's mane jellyfish is a very primitive coelenterate, and also one of the largest jellyfish species. It washed ashore on a Massachusetts beach in 1965. Its bell diameter was 2.3 meters, its tentacles were 36.58 meters long, and when its tentacles were stretched out, the length from tip to tip of one tentacle was 74 meters. Therefore, the Arctic lion's mane jellyfish can be considered the longest animal in the world.

It is native to East Africa. It prefers to live in dark, damp, loose, humus-rich environments. White jade snails are hermaphroditic. As long as the temperature and humidity are suitable, they can reproduce year-round. White jade snails have high comprehensive utilization value. The largest white jade snails can reach 30 cm in length, with a shell height of 15.4 cm and a diameter of 8 cm.
5. The largest snail – the crown snail
The Triton's Crown Conch is one of the four famous conches (the other three being the French Conch, the Phoenix Conch, and the Nautilus). It is highly ornamental and has significant collectible value, with distinct regional characteristics. It is a voracious bivalve that prefers damp, low-lying areas. Its name, Triton's Crown Conch, comes from its round shape with stripes in the middle and horns along the edges. Triton's Crown Conch is a large, precious conch, reaching up to 30cm in length and height.
