Dictyota dichotoma is a common brown alga with repeatedly forked, flat, olive-green to golden-brown fronds forming broad, fan-like thalli. It inhabits intertidal and shallow subtidal rocky shores of temperate to tropical seas worldwide. This photosynthetic macroalga anchors to rock via a holdfast and can reproduce both sexually and asexually.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
