What is the periodic round trips from breeding and non-breeding areas by birds?
The periodic round trips from breeding to non-breeding areas by birds is known as migration. Birds migrate to take advantage of better food sources, milder climates, and opportunities for breeding and raising young. Migration patterns can vary widely among bird species, with some traveling short distances and others undertaking long journeys spanning continents.
What is the binomial name of the Leech?

eg. Hirudo medicinalis is the binomial name of the European common leech.
What allows angler fish to live so deep?
Anglerfish have large, efficient gills that allow them to extract oxygen from the deep-sea environment. They also have slime-producing cells on their skin that help reduce friction and increase buoyancy. Additionally, their slow metabolism and efficient energy use help them survive in the nutrient-poor deep-sea conditions.
What are Wild rabbits feeding habits?
Wild rabbits are herbivores that mainly feed on grasses, clover, and other leafy plants. They also consume bark, twigs, and buds. Their diet is high in fiber to aid in digestion, and they are known to graze for several hours a day.
Aristotle is often credited as the "father of zoology" for his extensive studies and classification of animals in ancient Greece. His work laid the foundation for the field of zoology as we know it today.

Why does a hermit crab live in a snail shell?
A: Like turtles, snails are attached to their shells. They cannot leave their shells and live. If the body is out of the shell totally, the snail is dead. A few people have sworn their snail was alive, out of the shell, driving around. It must have been the current in the tank making their body appear to move. Snails cannot live out of their shells.

Moon jellyfish have behavioral adaptations such as vertical migration to follow food sources, pulsing movements to propel themselves through the water, and the ability to orient themselves using light to stay near the surface where they can feed efficiently. They also exhibit phototaxis, moving towards light sources for feeding and reproduction.
What is an antonym for mutualism?
Mutualism is the interaction between two species that is beneficial to both. Therefore the antonym would be competition, which is an interaction where both species are harmed.

Earth's climate cooled, which caused ice ages. Thick glaciers formed. The level of the ocean fell by more than 100 meters. Then the climate began to warm. Continental glaciers melted. Mammals became common.
What are the influences of genes on personalities of twins?
Identical twins are a useful tool in study of effet of genes and environment on genetic traits including human behaviors.This study is done by keeping identical twins in same environment and in different environments. Experiment performed by this technique indicate that genes have 66% effect on behaviors etc. while environment have 33% effect.This is called concordance.Identical twins show similar behavior (66%) even if reared apart in different environments which is due to same genes.
Some animals that cannot jump include snakes, slugs, and ants. These animals have evolved other forms of locomotion that are more suitable for their environment and lifestyle.

Why do bats and other animals sleep in daytime and are very active during nighttime?
Bats and other animals are nocturnal, meaning they are specially adapted to be active during nighttime because it offers them advantages such as reduced competition for resources and decreased predation risk. They have evolved to have heightened senses, such as superior night vision or echolocation, which help them navigate and hunt more effectively in the dark.
What is a reintroduction program?
A reintroduction program is a structured process that aims to release captive animals back into their natural habitat in order to restore or establish a sustainable population. These programs typically involve careful planning, monitoring, and evaluation to ensure the success and well-being of the reintroduced animals.
