Spanish Mackerel ( Scomberomorus sp.) (?)
Tanah Merah, 10th April 2016
A bag of fish parts was found on the beach. Further inspection revealed that the contents comprised various parts of Spanish Mackerel. Whether these pieces of fish were purchased at the market, or came from a fish caught in Singapore waters is unknown. It’s also not known why these were dumped on the shore, although there is a possibility that these were intended as bait for some other marine creature.
Four species of Spanish Mackerel have been documented in the waters around Singapore and Malaysia, and these remains may represent any of these species:
Indo-Pacific King Mackerel (
Narrow-barred Spanish Mackerel (
Korean Seerfish (
Streaked Spanish Mackerel (
Another possible candidate is the Double-lined Mackerel (
Coastal Horseshoe Crab ( Tachypleus gigas)
Tanah Merah, 11th April 2016
This Coastal Horseshoe Crab had been entangled and killed in a discarded fishing net.
As we walked back to weigh the trash collected, we find a decaying Sea Turtle on the beach.
Second time seeing a dead Sea Turtle for me. I still haven’t seen one alive in the wild yet.
