Dwarf sperm whale: The 'pint-size whales' that gush gallons of intestinal fluid when surprised

QUICK FACTS Name: Dwarf sperm whale (Kogia sima) Where it lives: Tropical and temperate waters around the world. What it eats: Deep-sea squid, octopuses, crustaceans and fish. Dwarf sperm whales have an unusual way to protect themselves if they come under attack. When they feel threatened, these tiny whales release their intestinal fluid, turning the water red. Growing up to 8 feet 10 inches (2.7 meters) long, they are the smallest species of whale. They are even smaller than some dolphins, such as Risso's dolphins (Grampus griseus) which can reach 13 feet (4 meters) and bottlenose dolphins (Tursiops truncatus), which grow to around 12 feet (3.8 meters). These animals look so similar to pygmy sperm whales (Kogia breviceps) that it's challenging to tell the two apart. They were even believed to be the same species until 1966. At the surface, they don't usually approach boats, which makes them very hard to study. The life of these toothed whales is typically unhurried. According to the Whale and Dolphin Conservation, they tend to travel at a steady pace, and drift gently back under the water when they're ready to go back to deeper waters. They only dive suddenly when they're startled. If this happens, they also release their intestinal fluid, potentially in defense or as a reaction to feeling nervous — like a squid releasing ink. Related: Sperm whales drop giant poop bombs to save themselves from orca attack No other whales, except pygmy sperm whales, use this tactic to escape from danger. "Each dwarf sperm whale has a sac filled with dark liquid in its intestine," representatives from the National Oceanic and Atmospheric Administration Fisheries wrote. "The whale can release more than three gallons [11 liters] of dark, reddish-brown liquid — or ink — from this sac." This cloud darkens the water, making it harder for the predator to see, which helps the tiny whale to make its getaway. Their predators include large sharks and orcas (orcinus orca), and these pint-size whales are also threatened by entanglement, vessel strikes, and pollution.

Although little is known about their social behaviors, they are usually seen in small pods of no more than 16 whales. They prefer deep waters and can dive to over 1,000 feet (300 meters) to find food. They eat a variety of deep-sea squid, octopus, crabs, and fish — using echolocation to track down their prey. They are often found near continental shelves where they have access to lots of their food sources.

Kayakers and paddleboarders 'unknowingly' disturbing sea life
Researchers have warned kayakers and paddleboarders may be unknowingly disturbing whales, dolphins and seals in Scottish waters. Heriot-Watt University, with support from the Whale and Dolphin Conservation, has documented hundreds of interactions between vessels and marine study included more than 400 hours of land-based observations across five marine regions, including protected areas. Researchers said disturbances caused by kayaks and paddleboards were recorded in the Moray Firth, Clyde, Forth and Tay. The study suggested disturbances from fast-moving craft such as speedboats also occurred in every area. Dr Emily Hague, of Heriot-Watt University, said: "The truth is that all of Scotland's coastline is important habitat for marine mammals."Whether you're paddling off the coast of Fife or sailing around Skye, you're likely sharing the water with sensitive species."We want people to enjoy Scotland's waters, but to do so responsibly by keeping up to date on how best to respond should you spot marine wildlife."She added: "With a little more awareness and a few small changes, we can all help ensure that sharing the sea doesn't come at a cost to the animals that call it home." What is the advice? NatureScot's Scottish Marine Wildlife Watching Code advises people to:Keep a distance of at least 100m (328ft) from marine mammalsAvoid sudden changes in direction, speed or noise - especially in engine-powered boatsAvoid surrounding animalsLimit encounters to 15 minutes and move on if animals show any signs of disturbanceAvoid using fast moving craft for wildlife watching due to their speed, noise and collision riskGive seals on land a wide berth

All flipper, no flop — the best places to see whales in Scotland
With humpbacks and orcas, minkes and even sperm whales, Scotland is one of the best places to see these majestic creatures this side of a flight to southern California — with basking sharks, porpoises and the world's largest bottlenose dolphins a spectacular bonus. Lisa Drewe, the author of Islandeering, picks out five of her favourite places to see them from land. At the tip of the Eye peninsula, near Stornoway, Tiumpan Head Lighthouse offers front-row views across the Minch. Below it, the strait's deep waters attract whales, dolphins and porpoises, making it one of the UK's best land-based locations for spotting them. Look out for distinctive grey-and-white Risso's dolphins and fin whales, or join the Whale and Dolphin Conservation's Shorewatch team for expert-led sightings. Coll's wild waters are a summer hotspot for basking sharks, the world's second-largest fish; they're often spotted gliding through the shallows with gaping mouths. From the ferry port at Arinagour you can enjoy stunning views over Mull and the Treshnish Isles, while coastal walks reveal harbour porpoises and bottlenose dolphins. Keep watch from the shore or ferry — minke whales and common dolphins thrive around this quiet, wildlife-rich island. On Mull's rugged north coast, the Glengorm estate enjoys sweeping views across the Hebridean Sea, where minke whales, bottlenose dolphins and basking sharks ply the waters. The castle at the estate's heart watches over wonderfully wild landscapes, while the shoreline is a prime spot for marine life. Join the Hebridean Whale & Dolphin Trust rangers every Thursday for a guided whale watch before warming up in the café, or exploring the coastal trails. • Never mind the Med, I'm longing to be back on Mull Shetland's southernmost point is a prime spot for orca-watching, thanks to the semi-resident orca pods. From the towering cliffs here are panoramic views over seas where minke whales and porpoises also hunt. The lighthouse above has a welcome café, and a base to explore one of the most accessible seabird and puffin colonies in Britain. Expert advice is available from the on-site Whale and Dolphin Conservation Shorewatch team, or check the Shetland Orca & Cetacean Sightings Facebook page. • Sumburgh Head lighthouse review — like stepping into Springwatch The Deerness peninsula, on mainland Orkney's wild eastern edge, is a prime spot to watch dolphins and porpoises. Harbour porpoises are often seen gliding through the waves, while white-beaked, white-sided and Risso's dolphins also patrol these rich waters. Dramatic cliffs offer sweeping views of the North Sea, and there is a fabulous coast walk to the Brough of Deerness, a rocky outcrop that was once home to a Viking settlement.
