Lasiwen

**Lasiwen** atau ***Myotis*** adalah genus kelelawar yang beragam dan tersebar luas dalam keluarga Vespertilionidae. Kata benda " *myotis* " sendiri merupakan konstruksi Neo-Latin, dari bahasa Yunani " *muós* (berarti "tikus") dan " *oûs* " (berarti telinga), yang  harfiah diterjemahkan menjadi "bertelinga tikus".

## Penampilan dan perilaku
Telinga mereka biasanya lebih panjang daripada lebarnya, dengan tragus yang panjang dan berbentuk tombak, itulah nama bahasa Inggris dan zoologi mereka. Spesies dalam genus ini ukurannya bervariasi dari sangat besar hingga sangat kecil untuk kelelawar vesper, dengan sepasang kelenjar susu.

Lasiwen umumnya merupakan hewan pemakan serangga. *M. vivesi*, dan beberapa anggota ekomorf kelelawar pukat *Leuconoe*, memiliki kaki yang relatif besar dengan jari kaki yang panjang, dan mengambil ikan kecil dari permukaan air (mereka juga memangsa serangga).

## Umur panjang
Lasiwen tergolong berumur panjang karena ukurannya; pada tahun 2018, para peneliti mengungkapkan bahwa studi longitudinal tampaknya menunjukkan bahwa telomer *Myotis* tidak menyusut seiring bertambahnya usia, dan bahwa telomerase tampaknya tidak ada dalam metabolisme *Myotis*. 13 spesies kelelawar *Myotis* hidup lebih lama dari 20 tahun dan 4 spesies hidup lebih dari 30 tahun.   Spesies *Myotis* yang paling lama hidup, dan kelelawar yang paling lama hidup secara umum, diperkirakan adalah lasiwen Siberia ( *M. sibiricus* ); satu individu yang ditemukan pada tahun 2005 ditemukan berusia lebih dari 41 tahun pada saat itu.
