There are many ways for benthic animals to move, including swimming, recoiling, shrinking and crawling, floating, and swimming upright. The most common way is the swimming of fish, which uses the contraction of the trunk and tail muscles to twist the body from side to side, compressing the water backwards and causing the body to move forward, plus the swing of the fins to move the water forward.
The hippocampus is a relatively rare upright swimming animal, with its head upwards and its body diagonally standing upright in the water, relying entirely on the dorsal and pectoral fins for movement, and the fan-shaped dorsal fin plays the role of wave propulsion.
This is how the squid moves, sucking water into the gills through holes on the side of the body and funnel in front of it, and then excreting it from the body. This gives you the power to push from behind, allowing you to move forward quickly.
Different animals have a variety of activities that are suitable for themselves, which are different ways of activities evolved according to their own living environment, there is no superiority or inferiority, only suitable or unsuitable.

The activity methods of benthic animals include shrinking crawling, recoiling, swimming, swimming upright or floating, shrinking crawling is mainly sea cucumbers, recoil is mainly squid, upright swimming is seahorses, swimming is mainly fish, and plankton is mainly jellyfish.
Methods of movement of benthic animals
Sea cucumbers crawl mainly by stretching their muscles, and their speed is very slow, advancing about 4 meters per hour.
There are at least 200,000 species of marine life in the world, and they all have their own ways of moving.

Hello, the activities of submarine animals include swimming, recoiling, contraction, crawling, floating, upright swimming, etc., and the most common way is the swimming of fish, using the contraction of the trunk and tail muscles to twist the body from side to side, compressing the water backwards and prompting the body to move forward, plus the swing of the fins to move the water forward. The seahorse is a relatively rare upright swimming animal, its head is upward with a mountain mass, its body is obliquely upright in the water, and it relies entirely on the dorsal orange fin and pectoral fin for movement, and the fan-shaped dorsal fin plays the role of fluctuating propulsion. Do you have any questions that I would like to answer for you?
Characteristics of zebrafish activity.
The thousand-year-old king, the 10,000-year-old tortoise, but in England there is a toad that has lived for 6,000 years.
If it is a bird, it will fly, and if it is running on the ground, it will burrow into water or soil, and if it is trapped, it will signal for rescue.
