Fishes with a leptocephalus larval stage include the most familiar eels such as the conger, moray eel, and garden eel as well as members of the family Anguillidae. Glass eel is a developmental stage from the end of metamorphosis in the leptocephalus to the beginning of pigmentation. Leptocephalus larva undergoes metamorphosis and enters a stage called as glass eels, before entering freshwater. It has the shape of an adult eel, with small size and without any pigmentation. Following this stage the young eels are called “elvers”. You may be interested in Whale Falls and Whale fall communities .

It is the world’s largest nocturnal primate, and is characterized by its unusual method of finding food; it taps on trees to find grubs, then gnaws holes in the wood using its forward slanting incisors to create a small hole in which it inserts its narrow middle finger to pull the grubs out. This foraging method is called percussive foraging, and takes up 5–41% of foraging time. The only other animal species known to find food in this way is the striped possum. From an ecological point of view the aye-aye fills the niche of a woodpecker, as it is capable of penetrating wood to extract the invertebrates within. The aye-aye is the only extant member of the genus Daubentonia and family Daubentoniidae. It is currently classified as Enda
