Menschenhai

The largest predatory fish on Earth, great white sharks can reach 6 meters and 2,000 kg, inhabiting cool coastal and offshore waters in all major oceans. Apex predators employing ambush attacks from below, primarily on marine mammals, large fish, and seabirds. Despite their fearsome reputation, unprovoked attacks on humans are extremely rare. Vulnerable, with populations declining from finning, bycatch, and targeted fishing despite legal protections in many jurisdictions.

Biddulphia rhombus is a centric marine diatom with a distinctly bipolar, rhomboid to broadly lanceolate valve shape bearing prominent horn-like elevations. It inhabits coastal planktonic and benthic environments in temperate to warm seas worldwide. This photosynthetic diatom contributes to marine primary production in neritic coastal waters.
