Marine animals-Sea cucumber

1) When a sea cucumber encounters a hostile attack and cannot escape, it can use the method of splitting to escape, and its internal organs are quickly thrown out of the anus.

Sea cucumbers whose internal organs have been discarded can still be alive.

Marine animals-Squid

Its body color changes, mostly due to fear and excitement. During the breeding season, female squid use colorful colors to express their love for the opposite sex. They often paint stripes on their torsos, as if they were wearing beautiful pajamas. Among marine creatures, squids swim the fastest. It relies on the reaction force of the water spray from the funnel tube on its belly to move forward rapidly, and can jump out of the water to a height of 7 to 10 meters. The squid has ink hidden in its belly, which is rare in the animal kingdom. The ink sac is in the belly of the squid.

When a squid suddenly encounters a powerful enemy, it uses this special defensive weapon to save itself from danger.
