Hematophagy (sometimes spelled haematophagy or hematophagia) is the practice by certain animals of feeding on blood (from the Greek words αἷμα haima "blood" and φαγεῖν phagein "to eat"). Since blood is a fluid tissue rich in nutritious proteins and lipids that can be taken without great effort, hematophagy is a preferred form of ...

吸血 （Hematophagy ，来自 希腊文， haima “血”， phagein “去吃”）是某些特定 动物 取食 血液 的一种行为。 由于血液是一种富含营养 蛋白 和 脂质 而不需要花费过多努力获得的液体组织，因此特别是在一些小动物例如 蠕虫 和 节肢动物 中，吸血 演化 为一种取食偏好。 一些 肠道线虫，例如 Ancylostomids 以吸取肠道中毛细血管的血液为生；还有75%的 水蛭 种类，例如药用水蛭 Hirudo medicinalis，一种自由活动的蠕虫，也是著名的吸血者。 还有一些 鱼形动物，例如 七鳃鳗； …

Hematophagy, an almost exclusive and obligatory habit in Triatominae at all their development stages and both sexes, appears as the key feature of their biology, by which much of their behavior and their microevolution is explained. Even if the transmission of the parasite is due to the contact of insect dejection on the host skin, hematophagy ...

2018年1月25日 · Hematophagy (also known as sanguinivory) is the practice by some animals of feeding on the blood of other vertebrate animals (or in some cases the hemolymph of invertebrate animals). The first known hematophages (blood feeders) were the protomosquitoes, of which there is fossil evidence from 220 million years ago (Schutt 2008 ).

2018年1月17日 · Heme and iron are essential molecules for many physiological processes and yet have the ability to cause oxidative damage such as lipid peroxidation, protein degradation, and ultimately cell death if not controlled.

2023年5月31日 · The practice of feasting on blood is known to science as hematophagy. Since blood is a tasty, nutritious meal replete with proteins and lipids, scientists have learned that this phenomenon has likely evolved repeatedly and independently across all branches of evolution in mammals, birds, insects, worms, fish and more.

Hematophagy in insects contributes principally to reproductive success and has required substantial evolutionary adaptation to accommodate behavior, digestion, iron detoxification, proteins and lipid transport and water management, among other demands.

2009年5月24日 · Hematophagy (sometimes spelled haematophagy) is the habit of certain animals of feeding on blood (from the Greek words, haima, blood, and phagein, eat). Since blood is a fluid tissue rich in nutritious proteins and lipids and can be taken without enormous effort, hematophagy has evolved as a preferred form of feeding in many small animals, such ...

2020年7月17日 · Hematophagy, or the habit of blood-feeding, is a widespread feeding behavior, being found in several groups like insects, fishes, mammals, and birds . Several of these hematophagous species are able to transmit viruses, bacteria, and parasites during the blood-feeding behavior, which are harmful to the host, causing huge economic loss and ...
