Mengapa Hiu Selalu Bisa Menemukan Mangsanya?

Ilustrasi/bbc.com
Kita tahu ikan hiu adalah hewan berbahaya. Tapi ternyata mereka lebih berbahaya dari yang mungkin kita bayangkan. Ikan hiu memiliki kemampuan yang memungkinkannya menemukan mangsa, meski si mangsa bersembunyi di tempat paling terpencil sekalipun.

Di lautan, hewan-hewan yang menjadi calon mangsa ikan hiu kadang masuk ke celah-celah karang, dengan harapan bisa selamat. Tetapi, hiu memiliki sel-sel istimewa dalam otaknya, yang sangat sensitif terhadap medan listrik yang terdapat pada tubuh makhluk lainnya. 

Karena hal itulah, hiu selalu dapat menemukan ikan lain yang bahkan bersembunyi di bawah pasir, karena hiu dapat menangkap sinyal listrik yang dipancarkan dari urat-urat tubuh mereka.

Hmm... ada yang mau menambahkan?

Spinning the wheels of change in Bali

With Bali’s Mount Batur looming in the distance, a car comes to a stop in front of a house in a village in Kintamani. “We are here,” says I Wayan Karmen as he clambered onto his wheelchair.  Karmen is here to meet a fellow wheelchair user as part of Yayasan Cahaya Mutiara Ubud’s (CMU) outreach, a foundation established by Persons with Disabilities (PWDs) to help other PWDs. “We usually go visit them to see what their conditions are like,” says Karmen, who is Secretary of CMU. “Because of their physical condition, they're shy and feel inferior compared to others. We want to build confidence in each PWD.” An estimated nine per cent of Indonesia’s population have some form of disability. PWDs continue to face challenges in accessing basic services such as education, social protection including health insurance, and have trouble finding employment. In Bali, one of the main obstacles faced by PWDs is a lack of accessibility, with few ramps and other mobility aids in public spaces like s

Mengapa Fosil Dinosaurus Tidak Ditemukan di Indonesia?

Ilustrasi/pixabay.com Kita sering membaca berita penemuan fosil-fosil dinosaurus di banyak negara, tapi kita belum pernah menemukan berita tentang penemuan fosil dinosaurus di Indonesia. Nyatanya, dari dulu sampai sekarang, belum pernah ada fosil dinosaurus yang ditemukan di Indonesia. Mengapa? Karena dinosaurus hidup di masa mesozoik. Pada masa tersebut, benua-benua yang ada sekarang masih menyatu dalam satu daratan superbenua yang disebut Pangea. Kepulauan Indonesia, sebagaimana yang kita kenal sekarang, pada masa itu belum terbentuk. Karenanya kita tidak menemukan fosil dinosaurus di Indonesia. Dinosaurus punah pada masa sekitar 65 juta tahun yang lalu. Sementara daratan Indonesia baru berumur sekitar 30 juta tahun.  Fosil hewan yang mungkin ditemukan di Indonesia hanyalah hewan-hewan purba berumur 10 sampai 20 juta tahun lalu, seperti gajah purba, mamalia purba, atau manusia purba yang ditemukan di Sangiran. Tapi usia fosil manusia purba tentu masih lebih muda dibandingkan yang lai

Our better lives and environment

  "Tourism in Ulu Geroh started in the late 90s, when some researchers from Malaysia Nature Society visited us and explained that the presence of the Rafflesia flower could turn Ulu Geroh into a tourism attraction and provide an additional source of income. We villagers had a meeting and subsequently formed SEMAI. The acronym is not only the name of our tribe; its meaning reflects our eco-friendly lifestyle and philosophy. In the early 2000s, I got involved in eco-tourism activities as a guide. Ulu Geroh has one of the highest concentrations of Rafflesia in the world, as well as the Rajah Brooke birdwing butterfly, so these are our top two tourism products.  When we have big groups, I bring in guides from other villages to help out. The biggest group we’ve handled so far consisted of 130 people from China – I had to hire 30 guides to take them on the trails! Daytrippers usually come just to see the Rafflesia flower, but we started offering homestays after a corporate sponsor funde
