Giant scolopendra - how poisonous millipedes live and eat
Content:
One of the most dangerous and repulsive animals on Earth is a giant scolopendra. She is extremely fast, secretive and aggressive. The predator attacks not only insects, rodents, birds and lizards become its prey. Skolopendra agility is evidenced by cases when they climbed the cave ceiling to catch a bat. Holding the prey with the forelimbs, the animal clung to the surface with just a few hind legs.
Appearance and habitat
The Latin name for the representative of the leg-footed centipedes is Scolopendra gigantean. They live in South America, on the islands of Jamaica, Haiti, Trinidad. The places where scolopendras live are tropical and subtropical moist forests. The body of the carnivore consists of 21-23 segments, each with a pair of legs. The average length of the giant is 30-35 cm, but cases of the capture of an arthropod 45 cm long are known.
Millipedes have a lifespan of 3-7 years. When they grow, they molt several times, dropping the chitin exoskeleton. Before molting, the scolopendra does not hunt for several days. The shell cracks, starting from the head, and the centipede creeps out of it, becoming 1.5 cm longer.
Interesting fact. Mavericks by nature, scolopendras in nature rarely conflict with each other. If the males bite each other in fights, then in half the cases this leads to death. In captivity, adult offspring from hunger are young offspring, cannibalism is not observed at large.
A giant scolopendra captures the prey by the front pair of limbs, transformed into the maxilla with claws and poisonous glands. The hind legs are longer, they repel the animal when moving. Each limb 25 mm, at the end of a sharp claw. Their eyesight is poor, so the scolopendras do not think long before the attack, preferring to immobilize everything suspicious with poison.
Scolopendra looks like all millipedes - a segmented body with many moving limbs. On a flat head, a pair of jointed antennae is noticeable. At their base are simple eyes. Its coloring is all kinds of bright colors, their shades and combinations. There are black, red, orange, blue, yellow and purple millipedes. Due to their unusual appearance, they are a welcome acquisition for collectors. Many people keep scolopendra in the terrarium.
Lifestyle
How does scolopendra attack
Animals go hunting at night, preferring to wait out the heat of the day in the shelter. What does scolopendra eat? She is a predator, so in her diet only caught prey. Invertebrates and small animals cannot be saved from a swift throw and paralyzing poison. Young individuals feed on insects, adults attack all who do not exceed the size of the scolopendra itself. It can be a small snake, a bird or a lizard.
Attention. The poison of a giant tropical scolopendra is dangerous for humans. It causes numbness and temporary paralysis. By pain, it is equivalent to a bite of 20 bees.
The millipede eats the victim for several hours, biting off pieces from lively but paralyzed prey. Its primitive digestive system, therefore, it takes a long time to saturate. After the meal, the animal is washed, passing through the jaw alternately antennae and legs.
Breeding
The breeding season falls at the end of spring - the beginning of summer. The male leaves a spermatophore - a bag with a seed, and the female creeps through it, picking up sperm. To lay eggs, the female digs a mink. This unpleasant animal is a caring mother. She guards the eggs and the babies that appear, clasping them with their feet. In one clutch there are up to 100 millipedes. Mother violently attacks everyone who approaches the shelter. She not only protects the eggs, but also cleans them so that they do not mold. Small scolopendras are white, their bodies are soft.
The family does not stay together for long, the scolopendra soon creeps away. Offspring are growing rapidly, experiencing several molts. The millipedes' body darkens, but the color will change until they reach maturity. Cases when larger individuals eat smaller ones are common.
Varieties of Scolopendras
Among the many families of leg-footed millipedes, tropical scolopendras are distinguished by a variety of species, large sizes and special danger. They are capable of causing significant harm not only to animals, but also to humans. European species are much smaller in size, their length does not exceed 8-14 cm.
