Party seeking coconut crab (Birgus festivus)
The party seeking coconut crab is a lively and highly social animal. Due to its pelagic larval stage it has spread to all tropical areas where it hangs around at beach parties and in hotel bars, preforming tap dance and begging for pina colada. As the animal is not known to spread any disease this rather annoying behavior is mostly tolerated.
