☆ Massive shark is struck by boat in rare video footage

CNN —Rare footage captured by a camera strapped to the back of an endangered shark shows the jarring moment it was struck by a boat — prompting the animal to dash into deep waters and rest for hours. It’s not clear whether the massive 23-foot (7-meter) animal, known as a basking shark, ultimately survived the collision. The basking shark is a massive creature, growing up to 40 feet (12 meters) long, and is among the largest fish in the world — second only to the whale shark. But the video and study findings that came out of the incident are timely for the shark research community, noted Dr. Christopher Lowe, the director of the Shark Lab at California State University, Long Beach. Protecting basking sharksMcInturf emphasized that Ireland — and the United Kingdom — have already taken significant steps to help protect endangered basking sharks.

☆ Starfish bodies are really just heads, new research says

CNN —The heads of most animals are easily identifiable, but scientists haven’t been able to say the same for sea stars until now. But new genetic research suggests the opposite — that sea stars are largely heads that lack torsos or tails and likely lost those features evolutionarily over time. There, they go through a process that transforms a bilateral body into a star shape, or pentaradial body. But echinoderms also share a common ancestor with bilateral animals, which adds to the puzzle researchers are trying to solve. Specific molecular markers act like body plan blueprints, directing each cell to the body region where it belongs.

☆ Scientists were 'shocked' to discover that juvenile white sharks regularly venture near swimmers and surfers but don't attack

Juvenile white sharks grow up to become great white sharks, known for being dangerous to humans. Why juvenile white sharks swim near humans so oftenFrom the researchers' drone footage, it may look like juvenile white sharks like to hang around swimmers and surfers. The shallow water near the beaches "is actually the natural habitat the juvenile white sharks use. Why juvenile white sharks don't typically attack humansAlthough great white sharks are infamous for attacking humans, the actual number of attacks is low. However, it doesn't mean the risk of a bite from a juvenile great white is zero — it's just very low.
