Life has been busy and stressful and very very strange but at least pathology can always be depended on - please enjoy this weird and invasive mammary carcinoma from a dog.

January was challenging and hectic, but February has been pleasant so far.

The Summer Games are here, so let’s meet the gold medal champion for fastest shark in the sea: the shortfin mako shark (Isurus oxyrinchus)! This agile predator fish is one of the world’s fastest swimmers, able to reach a top speed of over 40 mph (64.3 kmh). For perspective, the current 100m freestyle world record holder swam at an overall speed of 4.7 mph (2.9 km/h). A model of this shark can be found in the Museum's Hall of Biodiversity.

What has no heart and no brain? No, it’s not your ex… it’s the barrel jellyfish (Rhizostoma pulmo). Also known as the dustbin-lid jellyfish (yes, really), this species can reach an impressive 35 in (90 cm) in diameter and can weigh up to 77 lbs (35 kg)! Like other jellies, this critter relies on its nervous system to function.
