How do bugs move without muscles?
In a study published today in the journal Current Biology, the researchers show that the structure of some insect leg joints causes the legs to move even in the absence of muscles. So-called ‘passive joint forces’ serve to return the limb back towards a preferred resting position.
Do insects have blood?
A: Insects have blood, but it’s not like our blood. Our blood is red because it has hemoglobin, which is used to carry oxygen to where it is needed in the body. Insects get oxygen from a complex system of air tubes that connect to the outside through openings called spiracles.

What is the movement of fish called?
Fish swim by flexing their bodies and tail back and forth. Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side.

Does dragging a fish backwards kill it?
Knowing what you now know about fish, gills, and all the amazing wonder that fish are, you could be wondering can fish suffocate if they are pulled backwards through the water. The simple answer is yes, they can. Their gills can’t gain access this way as easily.
What fish can’t swim backwards?
Moving forward: Sharks are the only fish that can’t swim backwards — and if you pull a shark backward by its tail, it will die.
Is it bad if fish swim backwards?
This is because of the way the gills of fish work. The gills require water to move in the correct direction in order to enable a fish to obtain oxygen. When fish swim backward, the water does not reach the gills in the right direction, causing a fish to suffocate and tire out.
Is it normal for fish to swim backwards?
Can fish swim backwards? – The vast majority of fish swim forwards but most have the ability to swim backwards as well. Commonly the fish that swim backward are species such as the eel who use anguilliform (eel-like) locomotion to move their elongated bodies. Gobies are a perfect example of this.
What British fish can swim backwards?
Catfish, a non-native species in UK, has a whopping 27,000 taste buds compared to just 7,000 in humans. The eel is the only UK freshwater fish that can swim backwards.

Why do angelfish swim backwards?
The impaired buoyancy in fish is caused by a malfunction of their swim bladder. When affected by Swim Bladder Disorder fish will often lose the ability to properly swim. They will float uncontrollably to the top of the aquarium, turned upside down, while still being alive.
Does swim bladder kill fish?
The fish’s internal organs can press against the swim bladder and make it difficult for it to function properly. If you have a fancy goldfish or a betta fish, you’ll need to monitor it carefully for signs of swim bladder disorder. Left untreated it can lead to death.
