What is the smallest creature on land?
Also known as the white-toothed pygmy shrew or Suncus etruscus, the Etruscan shrew is the smallest mammal by weight alive today. At 36–52mm long, excluding tail, it’s larger than Kitti’s hog-nosed bat. However, individuals can weigh as little as 1.5g, meaning the Etruscan shrew takes the crown.
Who is the smallest animal in the room?
Etruscan Shrew The Etruscan shrew (Suncus etruscus), also known as the Etruscan Pygmy Shrew and the White-toothed Pygmy Shrew, weighs only 0.04–0.1 oz (1.2–2.7 g).
What are 3 ways animals disperse seeds?
Wind, water, gravity, ballistic (where the seeds are ejected by forceful and often explosive mechanisms) and animals are the main ways seeds are dispersed. For many different plant species, dispersal increases chances of survival as the seeds are transported to more favourable environments for growth.
Do bees disperse seeds?
Bees in particular provide an essential mutualistic service to plants: pollination of their flowers. They can also act as seed dispersers for plants, a rare seed dispersal mutualism termed melittochory. One group of known bee seed dispersers are stingless bees (Apidae: Meliponini).
How do sunflower seeds disperse?
Birds and animals love the seeds but often drop them when carrying them. Other animals horde them, burying them underground and effectively planting a seed to germinate the following spring. While many plants disperse seeds through fruit, this is uncommon among the sunflower family.

What is the most loved animal in the world 2021?
The big cat narrowly beat dogs, traditionally man’s best friend, in the poll carried out in 73 countries. TIGERS are voted the world’s favourite animal in a survey published today. The big cat narrowly beat dogs, traditionally man’s best friend, in the poll carried out in 73 countries.
Do ants move seeds?
Ants carry elaiosome-bearing seeds commonly known as “diaspores” to their nest, thus causing seed displacement. Inside the nest, the elaiosome is removed, fed to larvae, and the bare seed is discarded into a refuse pile inside or outside the nest (Servigne and Detrain, 2008).
How do plants pollinate?
Pollen from a flower’s anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.
How do sunflowers reproduce?
Sperm Meet Egg Once the pollen is forced down the stigma, it releases sperm into the stigma. An available egg receives the sperm, and the egg is fertilized with a meat-bearing seed. The pollen/sperm can belong to the original plant or may come from another sunflower.
What flower is dispersed by wind?
Wind dispersal Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have ‘winged’ seeds. They don’t float away but flutter to the ground.
What is the most loved pet?

What is the difference between pteridophytes progenetica and micromegethes progenetica?
P. progenetica (the specific name refers to the truncated development of the adult fish) is found in Sumatra and Bintan in Indonesia, while P. micromegethes (the specific name means small in size in Greek) hails from Sarawak. The former, with females maturing at just 7.
What is the function of the pelvic fin in Paedocypris?
The authors suggest that this is an adaptation for reproductive advantage. The pelvic fin could form a clasping device in conjunction with the prepelvic keratinised pad. Or it may be used to grab females during mating. Another hypothesis is that Paedocypris uses the pelvic girdle and fin to manipulate spawned eggs onto suitable substrates.
Is Paedocypris the smallest vertebrate?
