The yellow jumping spider is native to Ecuador and belongs to
the subfamily Amycinae. It’s body is so transparent you can actually see the retinas of the primary eyes moving when it’s tracking prey. Jumping spiders are known for their excellent vision, which aid in hunting, courtship, and general navigation.

Shark Week Countdown Challenge Day 4: Blacktip reef shark!
The blacktip reef shark hangs out in the shallow tropical waters of the Indian and Pacific oceans. It’s a small shark (~5ft) that makes small areas of a reef it’s home, feeding on the reef’s inhabitants.
Females give birth to live young, which are often seen in very shallow waters such as near beaches and shallow coral outcrops. These sharks pose very little risk to humans, being very shy and elusive. No one has ever been seriously injured by this species.
Blacktips are at some risk from fisheries pressure. They are listed by the IUCN as ‘near threatened’ due to declining populations in most of their range.

Rainbow roses

A pretty nifty DIY technique to make your own rainbow roses, and also a good introductory experiment for kids to show how plants transport water through capillaries in the stem.
